A precision digital voltmeter designed from the ground up using the ICL7107 integrated circuit. It features a clear 7-segment LED display for accurate voltage readings.
Understanding the fundamentals of analog-to-digital conversion is key in electronics. This project builds a functional voltmeter without using a microcontroller, relying instead on the specialized ICL7107 ADC chip.
It serves as an excellent educational tool for learning about circuit design, soldering, and component integration. The final product is a lab-grade instrument capable of measuring DC voltage with high precision.
