The Arduino is kind of like python in the embedded systems world – it’s not very hard to write something running at the extremely low power of 20mA, and there’s a huge wealth of library code one can pull in to power motors, lcd panels, etc. Most beginners of the Arduino would buy a starter kit that includes everything you need to get you need to get running assuming you have a computer and some spare time.
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.
