This post shows how I added an OLED status screen to my Raspberry Pi based Pi-Hole system.
Pi-Hole is a network wide advert blocker that you can run on a Raspberry Pi. It runs well on all Pi models and is an ideal project for older hardware. You can read more about it on the official Pi-Hole site.
Having setup Pi-Hole on a Raspberry Pi B+ I wanted a way to add a display so I could quickly check it was working. So I added a cheap 0.96″ OLED display and a momentary switch. The switch allows the display to show additional detail as required. The LED is there to add a nice coloured glow to the box but of course this optional.
