An Arduino drives the switch-mode power supply, offering dimming thanks to PWM, and the ability to automatically switch the light on and off using an RTC chip with a battery backup. The sketch ...

The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.

While the main supply can power the RTC, you may need to use a separate supply for this device to ensure it functions as intended even when the Arduino is turned off or disconnected from the main ...

a real-time clock (RTC) that provides accurate date and time, and a voltage-dependant temperature sensor. The Arduino Nano and Raspberry Pi Pico have distinct pin configurations. The Nano includes ...
