This electronic circuit project is a simple four channel digital voltmeter with display and keyboard . This four channel digital voltmeter is based on PIC16C71 manufactured by Microchip Technology . The PIC16C71 device’s I/O ports have an improved sink/source specification. Each I/O pin can sink up to 25 mA and source 20 mA. In addition, …
We are all aware of about voltmeters (voltage meter), which is nothing but a device used to measure voltage between given two terminals. Apart from the basic usage digital voltmeters are also employed as panel meters for automation systems and robotics. There are analog and Digital voltmeters are available in the market. Have you ever …

Summary: The speed of the motor is measured in Rotations per Minutes,RPM.The RPM Meter is to read the running speed of Motor like DC MOTOR. Here the speed of the DC Motor is sensed with the help of a speed sensor and it is signal conditioned to have pulses which given as Timer1 clock input …
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) …
The 3rd harmonic distortion meter has been designed for measuring the quality of AC supply. The meter is built with a PIC18F2550 project board and the full wave rectifier front-end circuit. The AC power line, 220VAC is measured through the step down isolation transformer. The input signal to the 10-bit ADC is full wave rectified. …
Bluetooth Wireless Voltage Meter using Wiimote + Pic Chip + AutoIt In this tutorial I’m going to be showing you how you can send voltage values to your pc using a Pic chip, Wiimote, and Autoit3 scripting language. The process works by wiring a pic chip to the button pads of a wiimote. Then using …
