Compare two Arduino capacitance-estimation methods – ADC-threshold timing and RC-derived values – and why leakage, parasitics and timing resolution dominate.

The cool thing about an ACS712 is that current is measured is measured in two directions.  What this means is that if we sample fast enough and long enough,  we sure to find the peak in one direction and the peak in another direction. With both peaks known, it is a matter of knowing the […]

Introduction Hello all, The Chinese Rings Puzzle with Arduino is my version of a centennial Chinese puzzle. It is very simple to play and it is an example of a combinatorial puzzle, and lots of patience and concentration is required to solve it. The objective is to untangle the long loop from all nine rings, […]
