| + | [title] Easier method |
|---|---|
| + | [* black] An easier way: press one side of a coin battery to one of the LED leads (still in the plug), and then use a pair of metal pliers to simultaneously touch the other lead to the OTHER side of the battery. The piers act as a conductor to complete the circuit. If it doesn't work, also try turning the battery over- LEDs only conduct in one direction. |
