For my take apart assignment, I chose to take apart a motion activated Ikea light.
Some things I found interesting
A. INPUT: The light senses motion through this sensor. The sensor originally sat in the middle of the circuit board
B. PROCESSING: The circuit board processes the movement and activates the output
C. OUTPUT: There are two light sources that are triggered from the sensor. There is an actual light bulb, as well as five LED lights.
D. ENERGY SOURCE: This light is powered by batteries. It looks like there were also two capacitors that store and distributes energy evenly to the light sources.
