PIC Harmonic Distortion Meter

PIC Harmonic Distortion Meter

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. …

A Digital temperature meter using an LM35 temperature sensor using PIC16F688

Introduction A digital thermometer is a good choice of project for beginners who just stepped in to the world of microcontrollers because it provides an opportunity to learn using sensors to measure the real world signals that are analog in nature. This article describes a similar project based on a PIC16F688 microcontroller and an LM35 …

Stand-alone Heart Rate Meter

This instructable describes how to build a stand-alone heart rate meter using Easy Pulse mikro sensor and mikroElektronika‘s clicker 2 for PIC18FJ board. An OLED W click board is also used to display the heart beat rate in beats per minute (BPM). The above figure shows all the things you would need to build this project. Step 1: Setup, Firmware, and …
