I’m always on the lookout for cheap electronics on eBay and AliExpress. Following on from my previous tutorial on HD44780 screens, this time, I found a small OLED display.
I bought one of these from eBay for less than £5 plus postage. It is a 0.96″, 128×64 pixel OLED display. These things are really tiny, but useful if you’re after something to display status information. They run from the I2C bus, this one using address 0x3C. This means that all the other addresses are available for you to use to get I2C sensor readings from or to drive other displays. You can even change the address on these displays to allow you to use multiple of the same device.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
