These 12 x 12 character grid clocks are operated with the Arduino Nano Every or a ATMEGA1280 chip and use SK6812 or WS2812 LED-strips to light the characters. These clocks have in my designs a ...

Want to make one for your desk? All it takes is an Arduino Nano R3 or comparable microcontroller, an RGB LED ring with 12 LEDs, a 16×2 LCD, a buzzer, and a momentary push button switch.

This study experimentally examined the energy usage of the ESP32 and Arduino Nano microcontroller boards in active and deep sleep (power-down) modes. Both boards were powered by a continuous 5 V ...

Then, light-pulse splitting is experimentally proven with a capacitor-LED-capacitor construction that is used to simulate the luminescence in NCI mode physically. Finally, we demonstrate light-pulse ...
