Now watch out the circuit diagram and make the connection as per circuit diagram…

1. Refer to the circuit diagram of the project.

2. Insert the clip on PCB board and paste it using hot glue.

3. Solder the connector to the base.

4. Solder a 100uF capacitor parallel to the connector clip.

5. Refer to the pin configuration of 7805. Solder the IC on the base such that, input pin is near the capacitor and connect input pin to +ve terminal of capacitor.

6. Take a 10uF capacitor and solder the +ve terminal to the output of 7805 I.C.

7. Refer to the pin configuration of female USB port. We have 4 pins

  • pin 1 – Vcc
  • Pin 2 – Data (-)
  • Pin 3 – Data (+)
  • Pin 4 – Ground

8. Solder the port to the base and connect pin 1 to the +ve terminal of 10uF capacitor.

9. Make all the ground connections.

Below Are some images to understand pin connection
