Step 2: Buy All of the Components

the components for this project are:

1pc 18650 lithium ion battery

1pc 18650 lithium ion battery case

1pc laser diode

1pc switch

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.
