This project was inspired by a forum member who asked a simple question: Can you interface a Trinket mini microcontroller to the Adafruit RGB LCD Shield. The shield is made to interface with more “classic” Arduino microcontrollers with an Arduino standard shield pin layout. Obviously the shield cannot stack onto Trinket but with four wires, the display shield can hook up to a Trinket project well. This is accomplished as both use the I2C or two-wire bus to communicate. As a further demonstration, the Adafruit I2C based DS1307 real-time clock module is used to display the time and date. The display shield’s buttons allow for changing the hour in case of daylight savings time and toggle the backlight.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
