![]() Compatible Nano V3.0 - ATmega328 Mini USB Controller Board + Cable For Arduino.Other websites/sources can provide similar products, just ensure the display is the same - and uses the I 2C communications protocol - not SPI. Start by programming the Arduino (ATMEGA328) using the Arduino software - there are hundreds of websites devoted to this topic so I won’t repeat them here. The source code is available from me, send me a message on the forum with your email address and I’ll sent it to you. Next, you will need to connect the display to the Arduino. To make the display fit inside the case, I had to remove the presoldered header pins and replace them with 4 wires. Make sure you leave these wires long enough to give yourself working room 15-20cm long is great. ![]() Connect the SDA (data) to the Arduino pin marked D6.Ĭonnect the SCL (clock) to the Arduino pin marked D7.The display has 4 connections - VCC GND SCL SDA Also use thin stranded flexible wire so you can bend and twist it as needed.Connect the VCC (+5v) to the Arduino pin marked VIN. ![]()
