Arduino Project to Product-Part 1-How to Accurately Measure Current

2019-06-20 | By Maker.io Staff

This video discusses project design power optimization to maximize battery life. Using a Digilent Analog Discovery 2, Shawn Hymel demonstrates the step by step procedure to accurately determine the current consumption of an IoT project to calculate average battery life. The pros, cons and pitfalls of traditional equipment and methods as well as low-side measurement are also discussed.
