Here is an artistic Arduino project for the fun-minded. The circuit is an Arduino RGB LED controller running on a sweet ‘n’ simple code,but with a little hardware surprise outside the Arduino board.

Welcome to our blog post on interfacing the WS2811 (5V) RGB LED strip with Arduino! In this guide, we will walk you through the process of connecting and controlling WS2811 LED strips using an Arduino ...

// Prepare a serial data object to receive three values (3) of 1 char long (1), the value will be an ARRAY // The array will have the 0 index for the R (Red), the index 1 for the G (Green) and the ...

#define qsuba(x, b) ((x>b)?x-b:0) // Analog Unsigned subtraction macro. if result <0, then => 0. By Andrew Tuline. float vImpact0 = sqrt( -2 * GRAVITY * h0 ); // Impact velocity of the ball when it ...

Infineon's RGB LED Lighting Shield is one two of Arduino-based evaluation boards created to showcase the capabilities of its ARM-based XMC1000 MCUs in lighting and motor control applications. Unlike ...

Building IoT projects with touchscreens used to be a headache, involving numerous components, messy wiring, and endless troubleshooting. But the ESP32-S3 Box-3 makes things way easier. It is an all-in ...

This system uses a colour-changing LED (RGB LED/tri-colour LED) that switches to a new colour every 5 seconds. Simultaneously, the colour name is displayed on an OLED mini screen (SSD1306). This ...

When you need to quantify the color of an object, you’ve got quite a few options. You can throw a Raspberry Pi camera and OpenCV at the problem and approach it through software, or you can buy an ...

Among quantitative analysis techniques, molecular absorption methods in the ultraviolet/visible region are the most commonly employed in chemical laboratories worldwide. In general, the absorbance ...
