Adafruit 0.56" 4-Digit 7-Segment Display with/I2C Backpack h

by uiaad on Wed Jul 31, 2019 11:42 pm

I will try and be as brief as possible, but I bought Adafruit 0.56" 4-Digit 7-Segment Display with/I2C Backpack and NodeMcu ESP8266 to create a youtube subscriber counter ( https://www.instructables.com/id/YouTube-Subscriber-Counter-With-ESP8266-V2/ ). Everything came, soldered up the backpacks programed the Node, hooked everything up and nothing. I mean the Node will output to serial monitor but nothing to the displays.

I then decided to test out each display one by one and opened up the Seven segment time display example as included with one of the adafruit libraries hooked, programmed the Node once more and hooked up the connections and still nothing. Tested both the displays and I have no idea why its not working.

If any one has any ideas i would be very very greatful :)

Post a picture of the display and the soldering. Do you have any other processors you could test the display with?
