The Arduino NanoV3 has a small footprint but all the possibilities of larger boards. AliExpress sells them for less than two Euro's (free shipping). Combined with H-bridge IC L293D and a PCB, we have a universal circuit that can control leds, DC motors, steppermotors, relais etc.
In this Thing, we make a LadyBot with two small geared DC motors. By setting the wheels in a different position, she really walks like a bug. A lot of in- and outputs are available for further development like a microphone and a buzzer.
Print in red, paint her head and dots on her back in black. No support needed.
The Arduino sketch shows how to change speed and direction of the two wheels independently.
