The RGB LED module lets you make all sorts of colors with just four pins from the Arduino. Learn how to do it here!

I could not figure out how to easily get the BW16 module to work with the FastLED library so I opted to use the APA102/sk9822 LED strips that use both data and clock lines and can be driven with the ...

Arduino Code for Interfacing MAX7219 LED Matrix Module with Arduino The code required to interface the SIM800L with Arduino is very simple and easy to understand.

Resistor, R1=150Ω, and capacitor, C1=220uF mentioned above are required for the pulse drive of the LED. Without the resistor and the capacitor, the module does not work.

[mircemk] built a slick-looking LED tester with a couple handy functions built in. Not only can one select a target current to put through an LED, but by providing a target voltage, the system will… ...

A few months ago I found a led driver module composed of a CN5711 IC, a resistor and a variable resistor. From the CN5711 datasheet: General Description: The CN5711 is a current regulation integrated ...

This project turns on and turns off a laser LED after every second. It can also monitor its own supply voltage level. It uses KY-008 Laser LED module.

Some microcontrollers like Arduino have very limited internal storage space, so an external EEPROM will be suitable for small amount of data storage or for extending the data storage capability of a ...

8×8 LED Matrix modules are now widely available, and fortunately they are easy to use with our favorite Arduino microcontroller. 8×8 LED Matrix module have many applications in real life, such as ...

In this project, the author would be creating a Talking LED Alarm Clock using TM1637 LED Module and a Arduino Development Board.
