    Buck converter using Microcontroller

    Hi, I desperately need the circuit design for the buck converter using the pic or any micro controller. I have calculated all the values and know all the components needed, the trouble that I am having is: Interfacing the micro controller to drive the MOSFET, by keeping in mind the...

    Problem with output voltage of a PWM generated by PIC

    i wrote a code to generate the PWM using PIC, I do not have the oscilloscope to measure the time periods. But when I measure the voltage across it using multimeter, it output 1.2v, Is not it supposed to be 5v? What am i doing wrong. I need at least 3.5v, as the MOSFET driver I am using...

    microcontroller kit desinging

    If you have never worked with the microcontrollers, It is not a big deal, I do not know about 8051, But If you want to work with Atmel or PIC chip, then there is plenty of help availabe on the internet. For Microcontrollers, all you need to worry about is: 1: Oscillator, connected to two pins...

    GSM Modem not replying 'OK'

    hhhsssmmm, Check datasheet for the modem, you might not need to connect the modem to the level converter, as most of the modems have builtin level converters. Added after 2 minutes: In that case you only need to use the Rx, Rx and GND pin of the GSM modem. Another soultion will be to connect...
