Bob Baddeley returns to continue helping Ben automate his workbench using Alexa and a Raspberry Pi. They’ve already gotten Alexa up and running, talking to a microcontroller over USB. It’s now time to automate everything else in the shop. They’ll use a multimeter and get a reading from it, they’ll go over the network connection to the oscilloscope so that they can change its settings and take screenshots with voice commands. They will interface a Gert Board with the GPIO on the Pi so they can turn bits on and off.
