Here is an Arduino based circuit with three independent pulse width modulated (PWM) channels to fulfil your requirements! Just follow the schematic diagram to complete the construction, and use any ...

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 ...

The flasher circuits below operate on a single 1.5 volt battery. LED flasher circuit diagrams. The circuit on the upper uses the popular LM3909 LED flasher IC and requires only a timing capacitor and ...

The code for the Arduino contains a loop that continuosly runs. The code sets the mouth LED pin to HIGH (The LEDs will turn on). Then the code sets the eye LEDs to high (Turns them on). Then there ...
