Summary of Digital Voltmeter using Microcontroller Atmega8
This project describes a digital voltmeter capable of measuring DC voltages from 0V to 25V, using an Atmega8 microcontroller. The internal ADC of the Atmega8 measures the voltage, which is scaled down to 0-5V via a resistor network. The measured voltage is then displayed on a 7-segment display.
Parts used in the Digital Voltmeter using microcontroller Atmega8:
- Atmega8 Microcontroller
- 7-segment display
- Resistor network
This project gives you a digital voltmeter which can measure voltage from 0v to 25V DC. The values are displayed over the 7segment display. Atmega8 is used and the internal ADC is used to measure the DC voltage. The resistor network is used to reduce the input voltage to the 0-5v.
