This arduino UNO project introduces a Sun-tracking system project using an Arduino Uno, a servo motor, and LDRs to optimize solar panel efficiency. Hardware components, circuit connections, and ...

The circuit connection for RGB LED Arduino interfacing is shown in below figure. Now for the tricky part, say we want to turn the RED led in SET1 and GREEN LED in SET2.

The circuit diagram of the LED flasher using Arduino is shown in Fig. 1. The circuit is built around Arduino Nano board (Board1), twenty coloured LEDs (LED1 to LED20) and a few other components.

Control motor direction, speed, and servo position. Light up the appropriate LED based on motor speed. Setup Instructions Assemble the circuit as per the provided instructions and diagram. Upload the ...

The author’s prototype is shown in Fig. 1 and circuit diagram of a rectifier using Arduino Uno is shown in Fig. 2. This circuit is built around Arduino Uno, centre-tap transformer X1, two diodes, a ...
