Introduction: LED Strip Blinker Circuit Using 12V Relay
Today I am going to make a circuit of LED Strip blinker using 12V Relay and capacitors.
Let's get started,
Step 1: Take All Components As Shown Below
Step 2: Connect 150 Ohm Resistor to Relay
Firstly we have to connect 150 ohm resistor to the Relay.
Solder 150 ohm resistor between NC (Normally close) pin and Coil-2 pin of the relay as solder in the picture.
Step 3: Connect 470uf Electrolytic Capacitor
Next we have to connect 470uf capacitor to the relay.
Solder +ve pin of 470uf capacitor to NO Pin of the Relay and
Solder -ve pin of 470uf capacitor to Coil-1 Pin of the Relay as you can see in the picture.
Step 4: Connect 2200uf Capacitor
Next Solder +ve pin of 2200uf capacitor to Coil-2 pin of the Relay and
Solder -ve pin of 2200uf capacitor to coil-1 pin of the relay as you can see in the picture.
Step 5: Connect LED Strip Wire
Next we have to connect the wires of LED Strip.
Solder +ve wire of LED Strip to NO (Normally Open) Pin of the Relay and
solder -ve wire of the LED Strip to -ve of both capacitors/Coil-1 pin of the Relay as you can see in the picture.
Step 6: Connect Power Supply Wire
Now we have to connect the clip of 12V DC Input Power supply.
Connect +ve clip of input power supply to Common pin of the Relay and
Connect -ve clip of Input Power supply to the -ve of capacitors/Coil-1 pin of the relay as you can see in the picture.
Step 7: Give Power Supply
Give Power supply to the circuit and now we will observe that LED Strip is blinking.
NOTE : Check circuit connections before giving input power supply.
