Helena, my lab helper and daughter assists in building a robot based on the Kitronic v2 motor driver board - a board adding this capability to the BBC Microbit. We write some code for it using Python to do the basics - and discuss the board.

Take a look with me at the Robot Cupboard in my lab - a backdrop for many of my videos - and at the robots and projects that lurk within. Some of which have been seen, some haven't yet been shown. In the video: esp8266, logibloks, the uArm based armbot, the maplin robot arm, A Lego Mindstorms NXT robot, Arachnid Labs cards, MIntygeek, Arduino's, Raspberry Pi's and robots.

In the previous live session, I soldered together a recording light on perf-board (https://www.youtube.com/watch?v=r_g3Zb8F69c) - in this video I start testing and troubleshooting it. The plan was to try and talk to it via serial and then WiFi, then clean it up. What happened instead was lots of troubleshooting part by part. In theory it should still have the original code I made, so this is mostly a test of my perfboard design and soldering. I needed to move some of the wires, measured voltages plenty (Thou Shalt Measure Voltages) and found I needed to tie different sets of pins to get more sense. Unfortunately I did not get it fully working - and will probably need to analyse it with the scope. Later testing (After the video) I found that the bootloader is outputting on 76800 - which I didn't try in the video. I suspect there will be more debugging but we now get: "rst cause:1, boot mode:(3,0)" - which may still indicate a GPIO pin at the wrong state (needing to be pulled up or down).
