LED Gumball Machine

Learn how to use serial I2C and SPI buses on your Raspberry Pi using the wiringPi I/O library for C/C++ and spidev/smbus for Python.

Not working as expected? In this tutorial, we will be exploring a few general troubleshooting tips and possible solutions that frequently come up with SparkFun's Technical Support.

Let's have some fun with LEDs! We'll explore LEDs once again with the SparkFun RedBoard Qwiic, making cool effects, and putting those effects to work using a sensor.

The What, How, Why, and When of Field Programmable Gate Arrays, aka FPGAs

Use the Tessel 2 and the Johnny Five Inventors kit to explore the world of JavaScript enabled hardware through 14 awesome experiments!

Sense various environmental conditions such as temperature, humidity, barometric pressure, eCO2 and tVOCs with the CCS811 and BME280 combo breakout board.

Freescale’s MMA8452Q is a smart, low-power, three-axis, capacitive micro-machined accelerometer with 12-bits of resolution. It’s perfect for any project that needs to sense orientation or motion. We’ve taken that accelerometer and stuck it on a Qwiic-Enabled breakout board to make interfacing with the tiny, QFN package a bit easier.

Get started with the Acconeer A111 SDK with a Raspberry Pi! The tiny A111 pulsed coherent radar (PCR) adds high-precision, cutting-edge distance measurement for speed-, material-, motion-, or gesture-sensing projects! We’re not talking about simple ultrasonic, or even infrared sensors here, but 60GHz radar!
