It’s just a simple digital clock controlled by Arduino without using any RTC module (Real Time Clock). Every time you switch on this clock you’ve to set it to the present time, just like the analog clocks found in homes.
My aim is to give beginners some understanding on how to work with Arduino using only simple materials and without lots of Incomprehensible codes. So let’s start.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
