By mastering Raspberry Pi GPIO control with Arduino Cloud, individuals can unlock the full potential of their IoT projects, creating innovative solutions that seamlessly blend hardware and software.

He ended up using multiple 74138 decoder/multiplexer IC’s to control the LED’s. Since the columns have inverted outputs, he couldn’t just hook them straight up to the LED’s.

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 ...

I've been planning out a project and need a little help. I want a device that can control an LED strip and play an audio file on loop when a button is pressed. I know I can use a raspberry pi on ...

Using an Adafruit FONA 800 shield, Adafruit TFT Shield w/Resistive touch, and an Arduino Uno developer board, along with a few other components, it’s possible to create your very own mobile phone.

Pulse Width Modulation is definitely the preferred method of dimming an LED with a microcontroller, but we were interested in hearing about a different method called Binary Code Modulation. BCM doe… ...
