Re: Sensors
Slide Potentiometer: These come in various slide lengths and are useful for some applications where linear motion can be measured. We used one in a our control box for controlling the launch angle of the shooter.
IR Photointeruptors: These can either be used as limit switches, rotational encoders or anywhere else you want to see if something is there. We constructed one using a IR led pulsed at 38khz and a IR reciever for sensing if a ball was in our scoop. The effective range of this sensor is between 1 foot and 30 feet depending on the current through the LED.
