This is a simple blinking led circuit powered from 220V that can be used to mark special places or as voltage indicator. The voltage from the mains charges the capacitor through R1 resistor and D1 ...
The “two flashing led” circuit is designed for 9 Volts but it works at lower voltages too. In this design we used red leds but by changing the series resistors R1 and R4 you can also use different LED ...

The author’s circuit wired on a breadboard for this purpose is shown in Fig. 1. The circuit diagram of Arduino based flashing light is shown in Fig. 2. The circuit comprises an Arduino Uno board ...
This project is a basic flip-flop (astable multivibrator) circuit that alternately blinks two LEDs using two NPN transistors, capacitors, and resistors. The circuit uses capacitor charging/discharging ...
The flashing is thanks to LEDs with a built-in, integrated flashing circuit and the nasty noise comes from a piezoelectric buzzer — both are available from electronics stores that sell ordinary LEDs ...
The main part of this LED chaser circuit diagram is 555 timer IC which generates some variable frequency. 555 timer IC is a general purpose IC which can be configured in some different modes like ...
Essentially, the circuit would be complete at this point, and three components would be sufficient for the function as a fuse monitor. However, with D3, another diode ensures that only half-waves ...
It is a pretty common first project to use an Arduino (or similar) to blink an LED. Which, of course, brings taunts of: you could have used a 555! You can, of course, also use any sort of oscillato… ...
