Ohm's Law
Analyzing voltage and current in a circuit is a great place to start to understand what that circuit is doing. In this episode of “Adventures in Science,” we introduce the resistor and use it to help demonstrate Ohm’s Law. This interesting law of physics was named after Georg Ohm, and states that the current between two points is directly proportional to the voltage across those two points: I = V/R With a little bit of algebra, we can move the variables around and arrive at the more memorable: V = I x R In the video, we demonstrate voltage and current in a fluid-based circuit, and show how a resistor acts like a piece of steel wool used to restrict the flow of water. We also construct a real circuit using a resistor, measure the voltage and current, and then calculate the resistance using Ohm’s Law. The information in the video was inspired by the following tutorials: Voltage, Current, Resistance, and Ohm's Law: https://learn.sparkfun.com/tutorials/voltage-current-resistance-and-ohms-law?_ga=1.172891943.529458105.1355161158 Resistors: https://learn.sparkfun.com/tutorials/resistors?_ga=1.173546663.529458105.1355161158 How to Use a Multimeter: https://learn.sparkfun.com/tutorials/how-to-use-a-multimeter?_ga=1.173546663.529458105.1355161158 I’ve gotten some good feedback on the previous tutorials, so thank you to everyone who commented! For this video, I put the “intuitive” demo first before touching any math, so hopefully that helps to make things clearer for students. What can be improved for episode 4?

What is Voltage?
Voltage is the electric potential difference between two points and is defined as the work done per unit charge to move a test charge between those two points. But how does all that relate to electricity? In this video, we'll show how electric charges can build up on surfaces, known as "static electricity," and how those charges can be used to define voltage. Obviously, a static electricity demonstration requires the creative use of balloons.

What is Electric Current?
When electric charges move, that's called current! In most circuits, this movement is accomplished by electrons in a conductor. As it turns out, an electron doesn't need to move very far; it can force other electrons in the conductor to move. In the video, we demonstrate moving electric charges with a tube and some metal balls. We also examine conventional current vs. electron flow and how good ol' Ben Franklin can be blamed for that bit of confusion.

Each Teensy 3.6 comes pre-flashed with a bootloader so you can program it using the onboard USB connection; no external programmer needed! You can program for the Teensy in your favorite program editor using C or you can install the Teensyduino add-on for the Arduino IDE and write Arduino sketches for it! The processor on the Teensy also has access to the USB and can emulate any kind of USB device you need it to be, making it great for USB-MIDI and other HID projects. The 32-bit, 180MHz processor brings a few other features to the table as well, such as multiple channels of Direct Memory Access, several high-resolution ADCs and even an I2S digital audio interface! There are also four separate interval timers plus a delay timer! Oh yeah, and all digital pins have interrupt capability and are 3.3V tolerant. All of this functionality is jammed into a 62.3mm x 18.0mm board with all headers on a 0.1" grid so you can slap it on a breadboard and get to work! The Teensy 3.5 (as well as its sibling, the Teensy 3.6) is larger, faster and capable of more complex projects, especially with its onboard micro SD card port. An upgraded ARM Cortex MCU (180MHz from 72MHz), more memory (1M from 256K), as well as more RAM, EEPROM and accessible pins make up the key new features of this “teensy” board. The Teensy 3.6 is slightly scaled up from the Teensy 3.5 but is offered at a higher price point, comparatively.

SparkFun 9DoF Sensor Stick
SparkFun 9DoF Sensor Stick: https://www.sparkfun.com/products/13944 The SparkFun 9DoF Sensor Stick is an easy-to-use 9 Degrees of Freedom IMU. The Sensor Stick deftly utilizes the LSM9DS1 motion-sensing system-in-a-chip, the same IC used in the SparkFun 9DoF IMU Breakout. It houses a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer – nine degrees of freedom (9DoF) in a single IC! The LSM9DS1 is equipped with a digital interface, but even that is flexible. The biggest difference between the two boards, besides the slimmed down 0.9"x0.4" footprint, is the number of broken-out pins, with the Sensor Stick featuring only four for quick setup and ease of use. The onboard LSM9DS1 is one of only a handful of ICs that can measure three key properties of movement – angular velocity, acceleration and heading – in a single IC. By measuring these three properties, you can gain a great deal of knowledge about an object’s movement and orientation. The LSM9DS1 measures each of these movement properties in three dimensions. That means it produces nine pieces of data: acceleration in x/y/z, angular rotation in x/y/z, and magnetic force in x/y/z. Each sensor in the LSM9DS1 supports a wide spectrum of ranges: the accelerometer’s scale can be set to ± 2, 4, 8, or 16g, the gyroscope supports ± 245, 500, and 2000°/s, and the magnetometer has full-scale ranges of ± 4, 8, 12, or 16 gauss.

The scanners have their own onboard memory storage for remembering fingerprints, which means you can move the scanner between projects, and it will still retain its database! To connect to the scanner, you will need a 4-pin JST SH connector. Note that the UART relies on 3.3V TTL signalling, so you will need to use a 3.3V microcontroller/computer or a logic level converter.

Electric Power
Power is the rate in which work is done, much like kilometers (or miles) per hour is a rate. The SI unit for power is the Watt, and it’s defined as one joule per second. Whether it takes you three seconds or one second to move 100kg to 1m above the ground, you use the same amount of energy. However, it requires more power to do it in one second. When it comes to electric power, “work done” refers to the ability of the circuit to transform electrical energy into something else, like heat, motion or sound. “Work done” can also refer to transforming some other form of energy into electrical energy, as in a battery, which converts chemical energy to electrical energy. As power is work done per unit time, with a little bit of math we find that electric power is defined as voltage times current: P = V x I. The information in the video was inspired by the following tutorials: Electric Power: https://learn.sparkfun.com/tutorials/electric-power Resistors: https://learn.sparkfun.com/tutorials/resistors

Adventures in Science: How LCD Works
Liquid crystal display (LCD) is a popular flat-panel display technology found in many TVs, computer monitors, smartphones, and tablets. The development of the LCD started with Friedrich Reinitzer experimenting with carrots in the 1880s and discovering that some chemicals can exhibit a “liquid crystal” state. RCA produced the first LCD in 1967, but it didn’t become really usable until scientists in Switzerland figured out how to manipulate the twisted nematic (TN) structure of liquid crystal with electricity. Today, LCDs rely on one of three different types of backlights: reflective, transmissive, and transflective. Most LCDs are transmissive, but reflective screens are still popular in things like calculators. Transflective screens have a backlight but can also be viewed in ambient light. They are, however, expensive and can lose some contrast. SparkFun’s LCDs: https://www.sparkfun.com/categories/76

Pi-Top (Green): https://www.sparkfun.com/products/13896 Pi-Top (Gray): https://www.sparkfun.com/products/13897 Raspberry Pi 3: https://www.sparkfun.com/products/13825 In this video, creative engineer Shawn takes you through the unboxing and setup of the green pi-top! The pi-top is a DIY laptop you build yourself that helps you start learning how to code, create awesome devices and take your knowledge to the next level. This Raspberry Pi powered laptop is an excellent resource to any budding hobbyist, student or intrigued user wanting to learn more about the capabilities of the credit card-sized development board. The only thing this kit doesn’t include is a speaker and its own Raspberry Pi; you’ll need to supply that on your own. We purposefully chose the pi-top without its own RPi due to the fact that most of you already own your own board and may not want to use a different or more expensive one. The gray pi-top comes with a 13.3" HD LCD screen (1366 x 768 resolution), a QWERTY layout keyboard with trackpad, a smart battery pack capable of running the pi-top for 10-12 hours, and a Hub PCB to take care of power management and a host of other functions. Don’t worry about cables or your OS either; everything to hook up each part in the box is included, along with the latest version of the pi-top OS on an 8GB microSD card. Assembly is easy – just plug or snap in all the parts with minimal use of the included tools. All pi-tops come preloaded with CEEDuniverse, a multiplayer online game that teaches you how to code, build circuits and make hardware that interacts with the game in real time. For example, you’ll be mining for resources in CEEDuniverse. However, you must program your mining bot in order to activate your Mining Machine. Speaking of mining, Minecraft comes pre-installed on each laptop as well!

SparkFun MPU-9250
SparkFun IMU Breakout - MPU-9250: https://www.sparkfun.com/products/13762 The SparkFun MPU-9250 IMU Breakout features the latest 9-axis MEMS sensor from InvenSense. Each of these 9DoF breakouts feature an MPU-9250 with a System in Package (SiP) that combines two chips: the MPU-6500, which contains a 3-axis gyroscope as well as a 3-axis accelerometer, and the AK8963, which features a 3-axis magnetometer. This breakout has been designed to be smaller than some of our other offerings to fit in smaller projects. However, if you plan to use a breadboard, or secure the IMU board to a project with something like epoxy, the mounting holes can be easily snapped off. To achieve its smaller size, the MPU-9250 Breakout features PTH pins that have been wrapped around the border of the PCB in three rows of three or four. The top row (J1) is all one needs to get the most functionality out of the IMU. These include the I2C and power interface. The second most likely to be used set of PTHs are found along the bottom (J3). This includes the address pin, the interrupt pin, and the IO voltage supply for easy interface with a more modern 1.8V processor. The third, a non-breadboard-compatible row (J2), is used for features like running other I2C devices as slaves to this one. For prototyping with these connections, throw your connections on top as you would with an Arduino Pro Mini or similar product. The MPU-9250 replaces the popular EOL MPU-9150 and decreases power consumption by 44 percent. According to InvenSense, “Gyro noise performance is 3x better, and compass full-scale range is over 4x better than competitive offerings.” The MPU-9250 uses 16-bit Analog-to-Digital Converters (ADCs) for digitizing all nine axes, making it a very stable 9 Degrees of Freedom board.

Product Showcase   Differential I2C Breakout
I2C is a relatively easy protocol to implement to communicate with one or more devices on a bus. However, it is limited in range and susceptible to electromagnetic interference (EMI). To combat these problems, differential I2C uses a set of differential signals to transmit SCL and SDA information over wires. To get even more distance, you can use twisted pair or shielded cabling. The SparkFun Differential I2C Breakout Board performs this translation for you and provides a set of Qwiic connectors along with an RJ45 to use CAT-5 or CAT-6 cables.
