The availability of cheap, high-efficiency LED modules helps add ... consisting of an Arduino Nano, linear regulator, power MOSFET and control switch, with a few discretes thrown in.

This is a where a Power Mosfet comes in. With the help of the Power Mosfet, we can use the low voltage output from the Arduino ports to control high voltage/current loads -the popular “12V LED strips” ...

Now is the time to see the sample code (Arduino Uno/Nano Sketch)… To summarize, infrared close proximity sensors are an effective alternative to some other electronic sensors and mechanical switches ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...
