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.

Move the MPU6050 sensor to control the arm’s base, shoulder, and elbow. The accelerometer values adjust the servos, allowing you to control the arm’s orientation based on tilt and position. Future ...

Components Required Arduino Board (e.g., Arduino Uno or Mega) Bluetooth Module (HC-05 or HC-06) MPU6050 Accelerometer and Gyroscope Sensor Servos (4x, for base, shoulder, elbow, and gripper) RGB LED ...

This is a great way to use an LED strip that would have otherwise gone to waste. If you can’t find a scanner with a color wand like this one, you can always start with an RGB strip.

Inside the is a Rainboduino: an Arduino compatible board capable of driving an 8×8 RGB LED matrix. Also stuffed inside the busy box is a 9V battery, rocker switch for the power, and four arcade ...

Our RGB matricies are dazzling, with their hundreds or even thousands of individual RGB LEDs. Compared to NeoPixels, they’ve got great density, power usage and the price-per-LED can’t be beat.

Guadagnini et al. (33) built a photometer consisting of a red LED (wavelength 620 nm), a BH1750 sensor, controlled by an Arduino NANO, showing applications for absorbance measurements in CuSO 4. dos ...
