Step 1: THE REQUIREMENTS
1) Zero Pcb.
2) 7805 IC ( voltage Regulator Ic)
3)Usb female port.
4)Connecting Wires (Ribbon)
Step 2: WORKING WITH ZERO PCB.
Step 3: SOLDERING VOLTAGE REGULATOR IC ON PCB.
After these cut the extra length pins of the ic from the zero pcb to ensure the ic is placed properly on the board.
Step 4: SOLDERING USB FEMALE PORT
Just place the usb female port horizontally on the board and solder it remove the extra length pins after soldering.
Tip- place the usb female port in front of ic such that the heat sink of the ic will face oppsite to usb female port.
Step 5: MAKING CONNECTIONS.
Jus connect the first wire in such a manner that it will ground to the first pin of the ic and connect second wire to the third pin of the ic and connect both the wires to the usb port .
Step 6: FINAL TOUCH
Tip- i used 9v battery in this setup.
Voltage regulator ic has voltage range from 7v to 35v.
