Switches

For week 2, one was expected to come up with creative applications of a switch. I decided to make a hand puppet / oven mitten – using a simple parallel circuit with 2 leds and a 3V supply.

As I began to build my circuit, I initially just made one without any resistors. This caused a short circuit, burning my led.

  1. Cute puppet! yes, a resistor would definitely help with each LED. You might also want to use a battery holder in an application like that, so that you can reuse the circuit when the batteries run out.
