Hi All,
I have attached a 24V Sensor to an Arduino Board that has been modified to have capability of 24V. The issue i’m having is I have it reading the sensor through an analog port therefore using the AnalogRead function. I am getting different readings for when the sensor sees something vs not however these readings have a bit of a delay to them. Am I over-looking something?
Thanks,
- Matt
A4 is the pin of the sensor.
