    measuring max battery current with multimeter

    connect your multimeter in series with a variable resistor and now keep multimeter in 10A range, when the supply to this ciruit is given, you will be able to measure the current drawn by the resistor, now by varying the resistance you can also find the maximum value of current that your battery...

    [51] Serial Communication in 8051

    instead of connecting the output of ir sensor to rxd pin, you can simply connect the output to anyone of the i/o port pins, for example, pc.0 so that the output of ir sensor will be in the 8 bit port c. if output of ir is 1 then the data in port c will be 00000001 .

    [SOLVED] need help on atmega8 interfacing to computer.

    hi, I have a atmega8 ic and I have planned to build a serial interfacing circuit for it with max232 ic and rs232 cable. the thing that I want to know is, what is software that I can use to transfer my programme(hex file) from computer to the microcontroller using rs232 and max232 interfacing.
