Hack Friday started a couple months ago buying a robotic head. It comes with two servo motors and two electric motors. About the same time I bought an Adafruit motor shield to control the head via an Arduino. I have not had time to wire it up with other projects like the Cylon Pumpkin. With Halloween over, I wanted to focus on the robot. Helping was receipt today of another Adafruit order from this past Sunday when they had a 10% off sale for Hack Friday. Just in time!
The head is driven with the motor shield’s two servo outputs and two of the four motor controllers. For now, a potentiometer is read to control the motor and a rotary encoder, interrupt driven, selects which motor to control (could be done with 4 potentiometers possibly better). The motor shield leaves enough Arduino pins free (all analog pins and digital pin 2 which is interrupt controllable). Eventually the head will respond to sensors and possibly talk via an Emic speech board coming from a sale at Make.
Making the hookup much more enjoyable is my new Hakko soldering iron – near instant controlled heat, making the old Radio Shack model seem so 1976.
I’m looking forward to seeing this project up and running (and talking) — it looks great so far!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
