🔧 Enhanced Performance with DIYmall 0: The Ultimate DIY Electronics Tool Review

Inexpensive and beautiful - I have used them in many projects. Note that the default address for Arduino is 0x3C (7-bit. More below). If they're left on all the time, some "burn-in" can occur, which manifests itself in the brightest pixels getting a bit dimmer, but A) they're inexpensive enough to replace occasionally B) they're still reading perfect with branding. In response to some reviews questioning the resolution - I've ordered a few and I can assure you they're all 128x64 - just make…

Most importantly, the hardware works well and the i2c saves a lot of GPIO. However, there are some gotchas in the backing zip file and it can be edited a little, although the instructions are easy to follow. I'm relatively new to Arduino and was able to connect this oLED display to an Arduino Uno R3 and upload a sample sketch using Arduino IDE 1.8.1 almost immediately. Nearly. My review is mostly based on supporting information and libraries downloaded from the link in the product description…

Works well after a little reading. I found that you do NOT need to set up a header file, just initialize the display with display.begin(SSD1306_SWITCHCAPVCC, 0x3C); Works on both Uno and Mega devices Uno PinoutSDA - A4SDL - A5GND - GNDVCC - 5vMega PinoutSDA - 20SDL - 21GND - GNDVCC - 5v Sample code for SSD1306 starts pushing the Uno's memory but Mega has no problem with it, to load the program. Being an OLED, it looks dead until initialization, which can be a little confusing when testing the…
