Accelerometer tutorial - what is an accelerometer?

How an accelerometer works!

Have you ever wondered how your phone’s tilt sensing function works? It uses a device called an accelerometer. In this video I explain some basic concepts of MEMS (microelectromechanical systems) and show you some MEMS dies under a microscope. Then I explain how these tiny structures can be used to sense acceleration. Accelerometer math

White LED under microscope

There are 3 dies on every white LED in this LED module.

Green LED turns red!

Normally rated for 20mA. When 100mA is flowing it turns from green to yellow. At 150mA, it slowly and permanently turns yellowy-orange. At 200+mA it permanently turns red and soon fails.
