Raspberry Pi Digital To Analog Converters is a new guide in the learning system. This small guide will help you connect and use an analog to digital converter with a Raspberry Pi:
The Raspberry Pi is an excellent small board computer that you can use to control digital inputs & outputs. However what do you do when you want to read an analog signal, like what you might get from a thermistor, potentiometer, or many other types of sensors? Don’t give up! By connecting a small analog to digital converter (ADC) chip to the Pi you can open up the world of analog signals to your Raspberry Pi programs!
This guide will show you a couple great options for reading analog values from Python with a Raspberry Pi. You can use a simple MCP3008 analog to digital converter (ADC) to read up to 8 channels of analog input with 10-bit precision. Or use a fancier ADS1x15 series ADC to read 4 channels with 12 to 16-bit precision, and a programmable gain stage–wow, fancy! You’ll be up and running in no time with a Python library and examples to read analog inputs from both these ADCs.
