A temperature sensor for instance may give out 2.1V when the temperature is 25C and go upto 4.7 when the temperature is 60C.
Almost all the sensors like temperature sensor, flux sensor, pressure sensor, current sensors, voltage sensors, gyroscopes, accelerometers, distance sensor, and almost every known sensor or transducer produces an analog voltage of 0V to 5V based on the sensors reading. Most of the Microcontroller projects will involve an ADC (Analog to Digital converter) in it, because it is one the most used ways to read data from the real world. In this tutorial, we will learn How to Use ADC with our PIC microcontroller PICF877A. If you are an absolute beginner, then please visit the complete list of PIC tutorials here and start learning.
Till now, we have covered many basic tutorial like getting started with MPLABX, LED blinking with PIC, Timers in PIC, interfacing LCD, interfacing 7-segment etc. This is our 9th tutorial of Learning PIC microcontrollers using MPLAB and XC8.
