Arduino ADC Explained: Using Analog Sensors for Your Gauges

In this video we take a look at using the ADC capability of an ESP32 / Arduino in order to add data points to custom car gauges that may not be available on the CANBus, and sort a custom PCB and controller to calculate the oil pressure rating on my Nissan 350z project car.
