“Instructables, and the internet, are so full of of barebone arduino projects that I hesitated to post this one. I mean I am not inventing something new here. I have received a good shipment of components from AliExpress yesterday and the first thing I made is one using a 2x8 cm pcb board and it actually came out quite neat. It was a soldering nightmare given the small size of the board and my insistence on having all the pins next to each other, something that I haven’t seen (although I’m sure I haven’t done anything new. someone somewhere must’ve done this before). The total cost came to US $3.7 and it took about one and a half hours to do given the amount of soldering work involved, and while it isn’t the smallest creation out there, it’s a pretty good sized one. So if you are interested to find out how did I manage to do this one, read on, and if you think to yourself “God not another one of those!” I won’t blame you if you navigate away :)”
