So, in the last batch of Electrocards I assembled, one of the displays had a very poor brightness. A fun project to see if I would be able to debug this issues.
Now that the hardware part of my Electrocard is done, it’s time to start working on the software side of my electronic business card.
If you you are a tinkerer that likes to play around with Arduino’s and electronics, you’ve probably played around with a 4 pin I2C OLED display more than once. To step up my game, I thought it would be fun to give myself a little challenge and try out a barebone OLED screen without the convenient breakout board.
