Electronics prototyping
04/23/2020 at 20:45 • 0 commentsTo plan out the electronics we will start with the following components:
1) 5V 1/64 geared stepperfor pellet dispensing, with Uln2003 stepper driver
3) Micro-servo (note the one in the photo is continuous but we will use a non-continuous one in the final build)
4) 2 BNC input jacks
5) Sharp GP1A57HRJ00F photo-interrupter on Sparkfun breakout board.
5) Adafruit M4 Express to control everything. This microcontroller is really overkill for this project but it has a built in RGB Neopixel which saves us from buying one more part, and it can run either Arduino code or CircuitPython for maximal flexibility!
