This video is kindly sponsored by https://www.PCBWay.com! Join me as we build a TZXDuino, from PCB through to programming the Arduino!

We go through the whole build, set up the Arduino IDE software with the required libraries and I explain how to program the unit (and where to get the latest firmwares).

🤞 PLEASE HELP MARK FIXES STUFF SURVIVE 🏆: Due to "The Event" my livelihood vanished in a puff of smoke. If you can spare some change to help support the channel it is really appreciated and even the smallest pledge goes a long way in helping make more content and feed my cats (and children).

You can order your own PCB from: pcbway.com/project/shareproject/TZXDuino_Shield_V2.html thanks to Zaxon who has kindly allowed me to host the files on PCBWay. Note that this is for the V2 board, with a motor control socket and the socket fix in the video already taken care of!
