  • I have a Data Logger project that I have been working on for a while. I kept breaking SD cards when my battery got low enough for the arduino to start acting funny. So what I did was used this UH-OH battery to be a voltage detector. I actually took the LED out of the board and have the LED terminals wired back to a digital input on my arduino uno, so when my battery dips to a certain voltage, say 6.5V when i am using a 9V supply, it flags a bit to stop running my arduino project, so I don’t kill any more SD cards.

  • Anybody have any suggetions for coding this micromag3 sensor to just read mG as an EMF detector? Trying to use it as just measuring emf on all three axis with no negative numbers. When not near a field it should register as a 0 or close to 0.

No public wish lists :(
