#Pick your LED lights and heat shrink. The two lights will form the robot's eyes. Optionally, get heat shrink tubing as well for added color. You won’t need more than 5 inches (13cm) of heat shrink for this project. | #Pick your LED lights and heat shrink. The two lights will form the robot's eyes.

#Shrink the heat shrink with a Soldering Iron. Start up your Soldering Iron and bring it close to the LED lights and the heat shrink. The heat from the iron should shrink the tube. Hold the LED with pliers to protect your fingers from the heat. | #Shrink the heat shrink with a Soldering Iron. Start up your Soldering Iron and bring it close to the LED lights and the heat shrink.
