Oled Display doesn't work #14

Hi there! Such a great job you are doing here. I really appreciate it. I am just starting on arduino and I am really bad at it. I am just an Electrician. The issue I have is about the Oled Display. The switch foot works great but the screen does not do enything. I've checked the librery and all is ok. Olso I checked the Oled Display with the Elegoo Uno R3 board and it works fine.

The board I have is from AZ-Delivery and the modell is ESP32-WROOM-32

The screen is too from AZ-Delivery and the modell is Oled Display I2C 128X64

I don't know what else to try. I'll aprreciate any sugestion.

Thank you so much.

Justin, awesome work on the Tinderbox.. Appreciate the work and wish I had the knowledge to do this kind of stuff.

I had the same issue as Tranks76 above. Switches work just fine (I did find a discrepancy between the schematic and the code - switches 3 and 4 were 'transposed' - I just flipped the wires) but I got nothing on the display.

Looking at a pinout for the ESP32 DevkitC, I found SCL is pin 22, not 23 as depicted in the schematic. Once I switched the SCL line to pin 22, the display came right up.

Hi Skiddz. I noticed too de discrepancy between the switches and the shcematic. And I did change the 22/23 pins and now the oled it works fine! Thank you so mach! so many time spended looking for the issue.

Hi all, I found the same two errors in the schematic. Buttons 3 and 4 transposed and SCL needs to be on GPIO22 as is standard. I hope the schematic is updated one day.
