pwm and basic stamp 2

dwaegerle

Hi im a senior in high school and for my final electronics project i am building a robot and instead of using servos im using dc motors and i was wondering if anyone could help me with it.· what im having trouble understanding is i know i have to build 2 h bridges but like i dont understand the pwm and h bridge coding for it and also if you guys can help me withy how to make the connection gfrom the h bridge to the basic stamp 2 it would be helpful i am also controlling it from a universal remote. I appreciate it. once i figure out what im doing i will post a video up of me controlling it along with the schematics. ·

My teacher just informed me we have a circut for the h- bridge so now im left with how to program pwm i can list the program im using if that might help

In order for us to give you advice or point you in the right direction, we would need the schematic for the H-Bridge. There are several different ways to make an H-Bridge and the signals they need depend on the design.

heres the information·you requested· and this is coming off of a ir remote

Hi dwaegerle,

Before anybody can offer any specific help you will have to, as Mike Green requested, post the schematic for the H-Bridge.

I'm sorry. You've not posted any information so far on the circuit you want to use or datasheets for the H-Bridge IC. There's good information on H-Bridges in the Wikipedia. Start there to begin to understand how they work and how they're used. Do a web search for "wiki h-bridge".

It's impossible to tell you how to control the I/O pins without more information on the H-Bridge. If you get the signals wrong you can destroy the H-Bridge.

Here's a 3 part article on motors and their control. Part 3 goes into h-bridges. members.tripod.com/RoBoJRR/motortech.htm
It's not a lot of detail, but does show some typical h-bridge ICs and examples of their use.
