I just added a voltage divider to my rover5 robot to monitor battery voltage. It is input to the EZ-b on an analog pin. The ADC gauge works neat as a fuel gauge. Wish it could be set to change color as the voltage goes below certain selectible points. The end goal is to get the the robot to say "Battery low" when the ADC pin becomes less than a certain voltage. I was looking for a script command like watch ADC port but there doesn't seem to be one. I suppose I could make up a script to check every 3 to 5 minutes with the alarm function but since the ez-b interface is periodically reading the adc port anyway to display the data it seems odd to have to use the alarm for that. An Interval timer would seem to be a better choice than using the alarm which I have to keep reseting to a new time every time it goes off.
Any thoughts from someone who has tackled this problem?
