Hello friends. Today we'll build a reverse polarity protection module for any voltage and current.

We'll rewrite the voltammeter sketch, adding an adaptive grid for data graphs.

We'll install a 10-amp shunt on the INA226 module. We'll also build another module for the future boss of all laboratory power supplies – a popular, beloved Chinese electronic load.
