Last time, we used a light sensor to measure the ambient brightness with an Arduino. When the light hitting the light sensor ...
In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...
Last time, we learned about the anode and cathode of an LED, how to distinguish their orientation, and the role of a resistor in limiting current.This time, we will combine an Arduino, a breadboard, ...
The 8x13 blue LED matrix is also an example of using PWM to implement gray-level images. The LEDs are connected in a row/column layout in the form of a tree – the first row has one LED pair, the ...
Flipping stairs is easy, but this project goes further by adding Arduino controlled LED lights to create SMART STAIRS. **Video Content Timeline:** 00:00 Intro 00:25 Removing the old carpet 01:32 Stair ...
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 ...
