For testing purposes I am trying to record sensor data from a Hall Effect flow meter using two Arduinos. Why??? Well, because I want to log data in a consistent manner while I also test and modify the code. It isn't practical for me to add a second sensor. If the modified code doesn't work I miss the data logging as a result.
Im thinking there is some electronic component I should be adding in to limit the Arduino boards from talking to each other instead of only to the sensor.
Is this possible? If so, any suggestions?
Sensor is a three wire... power, ground, and signal. I am also using interrupts (Yun is on pin 2) and (Micro is on pin 7).
