I recommend a Brachiograph build. It will introduce you to some fundamentals of PWM and inverse kinematics. It is well documented but not cookie-cutter. Using a Raspberry Pi will give you more direct access to running the servos than the microcontroller experience. All the parts are infinitely reusable afterward if you don't want to keep it around. https://www.youtube.com/watch?v=u4Jh1daCl60 https://www.brachiograph.art/ https://github.com/evildmp/BrachioGraph Sample Supply List for $80 budget: Pi Zero with header $20: https://www.adafruit.com/product/6008 Power supply $9: https://www.adafruit.com/product/1995 SD Card $10: https://www.adafruit.com/product/1294 Three hobby servos $18: https://www.adafruit.com/product/169 Breadboard wires $5: https://www.adafruit.com/product/153 Breadboard $5: https://www.adafruit.com/product/
