Happy Holidays from SwitchDoc Labs. In this tutorial, we are going to have a lot of fun. Did you ever want to read a voltage (rather than a 1 or 0) on your Raspberry Pi? You can do this with an Analog to Digital Converter.
Have you ever wanted to read analog (voltage level) levels and sensors on your Raspberry Pi? While you can read digital sensors with the Raspberry Pi, there is no built in analog to digital converter on your Raspberry Pi.
In this Tutorial, you will learn how use an 4 Channel 16 bit Analog to Digital Converter (ADC) on your Raspberry Pi.
There are many different reasons to read analog signals. Here are some examples:
What is the supply voltage on my Raspberry Pi?
What is the voltage on that resistor?
What is the O2 Level by reading the analog O2 sensor?
