In this article, you will learn how to run OLEDs by Arduino, and display text, images, and animations on them.
I want to make a CD spot welder for battery packs or other stuff that cannot be soldered.
Project in progress by Westpol
Sketch of transistor tester project from Karl-Heinz Kübbeler, so it's much simpler to study, modify, verify and upload to an Arduino.

Shoot sorry I copied the wrong lines into my original question! The lines that you have included in your previous reply have been uncommented and the lines I originally posted are commented out, which fails to work (the screen remains blank), thanks again for the help and sorry for the confusion!
Hi, thanks for the awesome project! I tried out your preview code Ardutester_more.ino with 2 different SSD1306 OLED displays but unfortunetly could not get anything to show up on the display:( I double checked that the i2c address was correct, and uncommented the lines
#define FOUR_LINE_LCD 0
#define WITH_LCD_ST7565 1327
#define LCD_INTERFACE_MODE 2
#define LCD_I2C_ADDR 0x3d
in makefile.h, is there anything more I am supposed to do in order to enable this display? I'm also using an arduino uno, and tried with and without the arduino uno defined in the makefile.h. Using the serial option, however, displayed the appropriate information for a tested transistor! Thanks!
