In this guide we will use our Circuit Playground along with some alligator clips and a resistor to explore how we can read digital inputs.
Learn about the basics of digital inputs, floating inputs and using pull up/down resistors, switch bouncing and a look at debouncing, as well as an ‘under the hood’ look at the push buttons on the Circuit Playground.
No soldering required!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
