The LinkIt One is a development board, created as a joint work by Seeed Studio and MediaTek. This instructable teaches you to make a decorative traffic light
Step 1: Materials
You will need:
1 Red LED
1 Yellow LED
1 Green LED
1 4 Position Switch
Step 2: Circuit
3 of the switches tell which LED to turn on and the 4th serves as a main power switch.
All the LEDs should already be grounded, and have the power wire extend from the out location on the switches.
Extend the wire from the main power switch to the power strip, and from their to the in spot off the switch.
WARNING: Using the LEDs with a voltage above 3v may damage them and is ill advised.
Step 3: Done
Congratulations! In this instructable you created a decorative LED traffic light using a 4 position switch and LEDS.
