hi everyone. I am working on a project where I need a LED to light up if the arm of the platform is horizontal. Due to space constraints I can not use an accelerometer. The sensor needs to be small and just give a high or low value at 180 degrees only with minimal error range, I am using an arduino nano as the microcontroler on the platform say at a distance of 4-5 inches. can somebody please suggest a sensor or positioning switch which I can use.
