Flip Flop LED Flasher
₹175.00
In StockA Flip-Flop LED Flasher is a simple electronic circuit that alternately turns two LEDs on and off in a continuous loop, creating a blinking or “flashing” effect. It’s commonly built using transistors, resistors, capacitors, and LEDs, forming an astable multivibrator — a basic circuit that oscillates between two states without any external triggering.
It’s often used for decoration, indicators, or learning basic electronics.
Description
A Flip-Flop LED Flasher circuit, also known as a blinking LED circuit, is a basic electronic project that demonstrates how components like transistors, capacitors, and resistors can be combined to create an alternating on/off switching effect between two LEDs.
This circuit is based on the principle of an astable multivibrator, meaning it has no stable state — it constantly switches between two unstable states, causing the LEDs to flash one after the other. The timing (blinking speed) is controlled by the capacitor and resistor values. When one transistor is on, the other is off, and vice versa.
The most common design uses:
- 2 NPN transistors (e.g., BC547 or 2N2222)
- 2 capacitors
- 4 resistors
- 2 LEDs
- Power source (usually 5V to 9V battery)
It’s a popular project for beginners in electronics as it teaches about charging and discharging of capacitors, transistor switching, and basic circuit behavior.

A Touch ON/OFF Switch is an electronic circuit that allows a device to be turned on or off by simply touching a sensor pad or wire, instead of using a mechanical switch. It works by detecting a small electrical signal from the human body (capacitive or resistive touch) and using that to toggle the output state.
These switches are commonly used in modern electronics, home automation, and DIY projects due to their durability, aesthetic appeal, and user-friendly operation.
