    High current H-Bridge

    Because I have to control the motor in both directions and this is the only circuit that I know to do this. Is there an easier? Thanks

    High current H-Bridge

    Thanks for all. I also believe that using MOSFET is the best choice. I've never made a circuit using them, so that I don't know what dificults I may found by build the bridge.

    High current H-Bridge

    I need to control a DC motor using PWM signal from a microcontroler. I found several componets easy to use but they are low current. The motor that I'm going to control works with 12V and 35 amps in pick. Once I will reverse it frequentily I think that I should make a project considering 35 amps...

    Digital circuit help

    I've made a board which has four 7seg. displays multiplexed. They are connected at the same bus and a PIC controls the turn on and off time of each one of them. The problem is that, in Brazil, PIC is not so cheap and I would like to use a digital circuit to make it. The project is kind of a...

    Layout problems!!! HELP!!!

    Hi all... I'm creating a board for PIC learners that has only leds, display e switches. To make this project, I'm using EAGLE but I found some problems with layout. The switches I have are differents from those which EAGLE has is its library. I have some with only two pins and others with six...
