Our project is infact an Arduino with Serially Interfaced MAX7219 Operates an 8X8 LED Matrix to display a heart pattern. The MAX7219 IC is a serial input/output common-cathode display driver that ...

This project demonstrates how to connect and control an external LED using an Arduino Uno. It’s a simple and fundamental project that introduces the basics of digital output. In this project, an ...

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 ...

Connect the four LEDs to Arduino digital pins 7, 8, 9, and 10, each with a 220Ω current-limiting resistor connected in series. Connect the other leg of each LED to a common GND pin on the Arduino.

The Arduino then controls the state of the LED using the active high enable line from the column multiplexer chip. [Alex] wanted more than just a static image to show off on his new display, so he ...

If you do it in hardware though, you’ll gain a lot more than coding skills. Just ask [Kelly] and [Jack] did, when they built this Arduino-based electronic Connect Four for a school project.

Connecting Arduino to Processing Introduction So, you’ve blinked some LEDs with Arduino, and maybe you’ve even drawn some pretty pictures with Processing - what’s next? At this point you may ...

Running out of GPIO pins? Learn how to connect multiple buttons to just one Arduino pin using clever wiring and resistor techniques. Perfect for compact projects, keyboards, or when using small boards ...
