    Parallel charging of batteries - Help please

    Hi all, I need help with a circuit so that I can charge two lead acid batteries on my car via the alternator BUT current is only drawn from the main battery which always gives me a fully charged battery on standby. Being a Newbie I thought of maybe adding diodes between the two batteries but...

    Simulation Problem

    Hi, If you have a look at : http://www.piclist.com you will find a delay generator there that produces code for any delay you want. I also found a neat little program that you can download that also produces the code for delay loops. Yhis can be downloaded from: **broken link removed**...

    uJDM Modification, need help!!!

    Hello amady, When I started out with PICs, my very first programmer was a JDM variant from Talking Electronics. They use a very clever method of using diodes and zeners in the circuit to make use of +8V and -8V to give you 16V via the serial port. I have never had any problems with this...

    PIC and Mosfet

    Hello all, When controlling a DC motor's speed with PWM and a MOSFET with a PIC ( FET I believe stands for Fire Emitting Transistor!!!! lol ) - the DC motor draws approx 10 Amps - what would happen if the Mosfet goes open circuit? ( and I beleive this happens with FET's ) As I understand the...

    beginners books?

    Hello, A good source of basics is at : **broken link removed** You can also try a Google search for: Pic Microcontroller E-Books The search gives you quite a few hits! Good luck and enjoy the PIC. It is a whole new world. Barry.
