AVR Project : Digital Voltmeter
This is a mini inexpensive AVR Digital Voltmeter Project with three digit display. It has also general purpose digital IO pins. So, you could use it as well to read a digital sensor and display the value.
The project can be freely programmed, calibrated and even be programmed with a non linear formula. It’s a display where you can define the relation between the measured value and the displayed number.
Interesting to build it ?
