the components for this project are:
1pc 18650 lithium ion battery
1pc 18650 lithium ion battery case
1pc laser diode
Step 3: Glue the Component to the Battry Case
Glue the laser diode and the switch to the battery case
Step 4: The Connection
the connection is really simple. The negative from the laser diode connect to the negative pin of the battery case. The positive wire connect to the switch then connect to the positive pin of the battery case.
Step 5: Testing
If you connect every thing correctly then if you press the switch the laser will turn on.
