Plant Watering Sensor - Precise Current Measurement

Posted on 2017-02-23— Projects

I struggled to measure microamp currents for my plant watering sensor until I tried the µCurrent Gold. In this post I show oscilloscope traces, energy estimates with and without LED flashes, and explain how the µCurrent converts current to voltage. Read on for measurements and upcoming PCB prototype details.

How to Debug Time Critical Code using an Oscilloscope

Posted on 2014-11-13— How and Why

I often use a simple oscilloscope trick to debug time-critical code: toggle an I/O line before and after critical sections and observe interrupt timing and execution width. It’s low-effort and revealing — read on for practical steps, examples, and tips to measure and reason about your timing issues.
