Resources and Going Further

The INA169 is a useful chip if you want to know how much current something is using. For example:

  • On The Uncertain 7-Cube, you can connect the INA169 inline with the battery's positive power wire (that's the red wire!) and measure the current draw to figure out how long your battery will last.
  • Similarly, connect the INA169 to the HUB-ee Buggy's power and determine how much time you get before you need to replace those AA batteries.
  • Or use the INA169 to determine how much power is being consumed if the Humidor Control Box is left on all the time.
