Hello,
my robot from robowatch (www.robowatch.com)has several interfaces,
where I can connect different sensors. I have connected an ultrasound
sensor. The robot's manual mentions a pull down resistor, which is
supposed to be connected to the ground. Why is this necessary? I find
this information in connection with many different sensors.
Many thanks for an explanation.
