Fig. 1: Circuit diagram of the LED flasher using Arduino. Arduino is programmed in such a way that only one LED glows at a time. A random number is generated by the program that is used to turn on the ...

Circuit and Working Explanation: Circuit Diagram of RGB LED Flasher is given below. We mainly need a Arduino, ESP8266 Wi-Fi module and RGB LED. ESP8266’s Vcc and GND pins are directly connected to ...

This circuit flashes 18 LEDs, for which it makes use of nine NPN transistors in addition to the other components. - Advertisement - In the 18-LED flasher, nine outputs of Arduino Uno are connected to ...

In recent years, the chapter ‘flashing lights’ in its many incarnations, has already received plenty of attention in Elektor Electronics. Therefore, a newly presented flasher circuit has to have at ...
