Active piezo buzzer for motor driver and precision resistors for temperature sensor …
↓↓↓ Complete description, time index and links below ↓↓↓

In the last video we’ve finished the first version of the RPM measurement based on the sinusoidal fluctuation in the motor current (link below). It’s time again for some housekeeping.

We start with wiring up the right kind of piezo buzzer – with a build-in driver – to the stock motor driver. Then we replace resistors within the temperature measurement circuit with precision ones.

00:00 Intro – it’s time again for some housekeeping
01:11 Piezo buzzer – of the correct type this time
03:59 Temperature sensor – replaced 5% wit 0.1% resistors
09:24 Wrap-up – I’m not sure what’s next, bye
