Voltmeter C# .Net PIC, Arduino, AVR This is a simple voltmeter which measures 0-5V at a precision of 4.8 mV. This is a simple design using inbuilt ADC of PIC 16F877A. PIC 16F877A have 8 channel 10bit ADC.   This is a computer interfaced project. Measured voltage is output in serial interface software in computer. There is a serial interface circuit (MAX232) is necessary for interfacing with computer, which is not included in the circuit. Please check       PIC Serial Communication Tutorial (UART)   for the circuit and more details. Using one of the most popular 8 bit PIC 16f877A, for instance, reading the datasheet , we'll find that the ADC modules (10 bit) are controlled by four different registers. The first two, ADCON0 and ADCON1 , are used to set and start the ADC module. When high level language is used, the programmer doesn't need to care a lot of the register connected to the results because they are normally stored in...
