| We love some good LED blinking as much as the next person but after years of LED-soldering we need something cooler to get us excited. Sure there are RGB LEDs and those are fun too but what comes after that? Well, we have the answer: **LED Strips**! These are __flexible__ circuit boards with full color LEDs soldered on. They take a lot of LED-wiring-drudgery out of decorating a room, car, bicycle, costume, etc. The ones we carry are also waterproof (although not all are). | We love some good LED blinking as much as the next person but after years of LED-soldering we need something cooler to get us excited.

| The Digital-type strips work in a different way. They have a chip for each LED, to use the strip you have to send digitally coded data to the chips. However, this means you can control each LED individually! Because of the extra complexity of the chip, they are more expensive. | The Digital-type strips work in a different way.

| - | Connect a 9-12V power supply to the Arduino sot hat **Vin** supplies the high voltage to the LED strip. If you want, you can also just use a separate wire that connects to a power supply that provides about +12V. Make sure to connect the ground of that supply to the ground of the Arduino/MOSFETs! | + | Connect a 9-12V power supply to the Arduino so that **Vin** supplies the high voltage to the LED strip.
