Persistence of vision or POV in short is commonly found in electronic projects and there are a multitude …
LCD Smartie PCB
If you’ve read my previous post on LCD Smartie, you’ll realise that I made my circuit on a breadboard. I liked it a lot so I decided to make a permanent PCB for it. I’m doing this so that I can practise my soldering too. I will be using a pre-made PCB because it’s quite a simple circuit. This is …
