A simple LED dot matrix clock project based on Arduino Nano (ATmega328), also using a DS3231RTC module and a LDR sensor.

The nano sensor interface presented below is a microcontroller-based universal sensor interface with a power-saver mechanism. The idea, centered around an Arduino Nano (v3) microcontroller, was ...

with the Pretzel board, the other components are also required. LDR is connected to the Arduino based NanoESP Board using breadboard. Also, LDR is used with 10kOhms resistor to form a voltage divider.

The massive quantity of electricity gets used in lights through roadways in India. Still, roadways remain empty for nearly all of the day after at night, with a handful of cars passing during the ...
