    [SOLVED] I2C Communication between multiple pic

    hi. i need an example to communicate between 8 pics as slave and one as master. Every slave have an led light and i want to make turn on or off from MASTER instruction. i want to use pic16f877a microcontroller for all (master and slaves). I have little bit practice on CCS compiler if any body...

    Volt Meter Design using Pic or Arduino

    i have made volt meter using this method . 1. find out Vmax of sine wave by taking 500 samples . 2. V=Vmax * 0.707 it works on sine wave but when i try to measure ac dimmer output or square wave of ups then it fails.

    Volt Meter Design using Pic or Arduino

    Thanks for your guidance. I just want to make copy of digital VOLT meter suppose this one . what ever this meter shows against pwm, AC dimmer output , sine , square , saw tooth, my meter should be equal. what should i follow RMS OR AVERAGE OR SOMETHING ELSE ? You can choos another meter as well
