Hi everyone!
Does anyone know if -and how- I can connect 1 sensor (IR range finder) to 2 separate Arduino boards at the same time?
If I just connect the 3 (2 Arduino/1 Sensor) 5V Pins together, the 3 (2 Arduino/1 Sensor) Ground Pins together & the 3 (2 Arduino/1 Sensor) AnalogRead Pins together will it work?
(Or is there a chance I might destroy the boards...?)
Or maybe connect all 3 IR Sensor Pins to 1 Arduino Board and just the AnalogRead Sensor Pin to both?
Thank you,
Sofia

I think your last suggestion is the best:
connect all 3 IR Sensor Pins to 1 Arduino Board and just the AnalogRead Sensor Pin to both?
With one modification: connect the 2 Arduino ground pins together too.
If I connect the AnalogRead Sensor Pin to both, would the 2 boards "interact" with each other and alter the signal?
Should I maybe use a transistor or something to stop them from doing so?
Thanks...
They shouldn't interact. The analog input does not disturb (much) the signal being connected to it. Just to be safe you may want to add 1k series resistors just before each analog input pin on each Arduino.
