Bar LED Dancing Light, Voltage : 110V

LED Dancing Light is a simple 6 LEDs multi vibrator using two transistor, to give dancing light effect. LED Dancing Light is the base of LED Flashing circuit. LED Dancing Light works on the principle of charging and discharging of capacitors C1 and C2. Current from the positive of battery flows through first set of LEDs D3, D4, D5, D6, D7, D11, D12 to the collector of T2 through resistor R2, R4, R6. Resistor R2, R4, R6 limits current through the LEDs to protect them. The current through R2, R4, and R6 charges capacitor C1. It then discharges through the base of T1 and resistor R9. This gives base current to T1 and it conducts. As a result, second set of LEDs D1, D2, D5, D6, D9, D10, D13, and D14 lights as the current flows through T1. Capacitor C2 again charges and the cycle repeats. The D1, D2, D5, D6, D9, D10, D13, D14 are red LEDs and D3, D4, D5, D6, D7, D11, D12 are the green LEDs. These LEDs flashes alternately and give dancing effect.
