Tilt Switch RGB Strip Setup

What do you need?

• 1x Microcontroller
• 1x USB cable
• 4x Jumper Wires
• 5x Female to Male jumper wires
• 1x 100 - 1000 Capacitor
• 1x 470 ohms resistor
• 1x Tilt ball switch
• 1x Addressable RGB led strip

Follow the layout in the sketch above to assemble your components.

Please keep your microcontroller disconnected from the power source while putting your components together.

If you connected all of your components correctly, your RGB strip should now switch on and off when it is tilted.

Above is a short video that will demonstrate how your tilt ball switch and RGB strip should be working together. If your setup is not working as in the example in the video, please go back up the page and re-wire your set up and check the code again.
