Wearable Technologies - LED Hat

* A square LED (Red).

   

* Testing out the LED.

* Connecting 2 LEDs in parallel.

*LEDs in parallel connection.

*Embedding the LEDs on the hat.

   

* Soft switch.

* Connecting cable (+) and (-) on the switch,

* 2 long cables will be connected to power supply.

* Mistake in connection :

- one resistor could not hold the entire connection.

* 3 100Ω resistors were added in the connection.

* To make the cable placed tidier, the cable is sewn on the hat.

* Battery holder at the back of the hat.

* LEDs lighted up.
