I'm following along with Shane's build, but doing all the software/firmware in MicroPython. Here's where I am so far:

I've been able to get the mp3 player, the microphone, the accelerometer, the PCA9685 PWM board, the ultrasonic distance sensor, and the TFT display all to work using MicroPython. Next up is leg assembly and working through how to control the motors and react to the sensor values.
