5. 22 ohms resistor
6. One empty hearing aid battery case for housing the compnent
Step 2: Soldering SMD LED's to PCB
Solder the SMD LED's to the PCB shown at the start.
Step 3: Connect Them All Together
Connect them all together as per the circuit shown in the picture.
Step 4: Fitting Everything Into the Case
Fit every thing in to the case. You will need to modify the case to fit battery and make necessary cuts to access usb charging and switch.
