Battery Monitor
« on: May 05, 2009, 07:28:47 PM »
So, I have my robot, and its a short run robot that runs off of 4 - AA NiMh cells for around 1 minute. And at the end of each run, the batteries are usually half drained or so.

What I wanted to know was what would be the best way for me to read the battery voltage with my Arduino so that I can display the value on an LCD that's connected to the Arduino, and then I would know when I need to replace the batteries with ease.

Also, if possible, somehow measure the current draw on the batteries and read that with the Arduino too.
