5. Build your own Mars Rover Robot using Arduino: This cool looking Arduino Project presents the construction of an Arduino-based Mars rover, emphasizing design, components, and assembly.It highlights ...

Circuit and working. 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 ...

Now Negative pins (1, 3, 4) of RGB LED is connected to Arduino Pin 2, 3 and 4. Here RGB LED is connected in reverse logic means if we make ground terminal of LED high, it will turn off. So here we are ...

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 ...
