What has eight legs, a tail, and is powered by an Arduino Mega? The ClearWalker, of course! This Strandbeest-style walker employs two motors, controlled by individual H-bridge relay modules to traverse forwards, backwards, and slowly rotate to one side or another via a hesitating leg motion. You can see how the electronics (including a bunch of LEDs) were integrated into this build in the video below.
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.
