Procure one Atmega328 chip with pre-burned Arduino Bootloader; Replace the original chip in your Arduino board with this one; Now upload the sketch to the 328 chip ,as usual, using Arduino IDE; Remove ...

I made this Arduino project that allows to turn ON and OFF LEDs using a cheap IR remote control as a preparation for the next big step: disassemble my girlfriend’s chinese LED lamp and replace its ...

He only ever lights up one LED at a time, but he scans through the 128 LED’s so fast that persistence of vision prevents you from noticing. To the human eye, it looks like multiple LED’s are ...

Here’s an Arduino library that will let you drive a very large number of LEDs. [Elco Jacobs], an electrical engineering student, is the author of the library. He has a work-study job that has… ...

The Arduino Micro is closely related to the Leonardo, with some small difference. Each led in both is connected in series with a 1kΩ resistor to limit current. One Leonard-Micro difference is with the ...

Driving multiple LEDs with one microprocessor GPIO pin is a well-known technique. Here's a way to accomplish the task that's simpler than other methods.

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 ...
