In this review, I thought I would combine Adafruit’s 0.56″ 7-segment LED backpack and display and their DS1307 RTC (Real Time Clock) board. The obvious choice for such a combination is to make a simple clock! Both modules are I2C and therefore just require two data pins along with GND and 5V. So, for anyone who has done their own multi-digit 7-segment LED multiplexing wiring up the breadboard becomes beautifully simple.
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.
