05:45 Exploded Capacitor
22:26 Smart Phone Charger Mini-Update
As part of my quest to replace the potentially dangerous electronics in a recently acquired fan speed controller, the first step is for the Arduino to know exactly when the mains AC waveform is at the zero point in its cycle.
Here we can see how easy it is to configure the Arduino with just a few lines of code to detect this using a simple interrupt routine.
We also have a 2 minute look at the progress on my Smart Phone Charger, as the PCB from JCLPCB has arrived and is looking good!
