I'm working on a project to monitor the water level in a funnel (to prevent overflow). I've just started and am at the point where I want to just power the sensor and connect it to the Arduino to play with.
I am using an Arduino Leonardo.
The eTape documentation says that it needs 6-32V input. My understanding is that the Arduino only provides up to 5V. Do I connect an external battery? How would I do that? The eTape sensor has pins for Vin, Vout, and GND. I'm assuming I would connect the battery to Vin and GND and the Arduino to Vout. Is that right? I'm completely new to electronics.
