I want to build on a remote control on motor direction, I have found a page on
http://www.geocities.com/naveen_pn/circuitspage.html
in the topic: DC motor direction controller
**broken link removed**
but I used 2N2222 instend of BC148, 2N4403 instead of SK100, and 2N3053 instead of SL100... will it affect the result?
It works:
when I put control input A into +9V and left B alone(clockwise)
when I put control input B into +9V and left A alone(anticlockwise)
However, it does not work while putting control input A and B into pin21 and pin22 of a AT89C51....whatever I put A HIGH and B LOW or A is LOW and B is HIGH
what should be added to input A and input B in AT89C51?
Pls help me.... really really urgent... for me in doing a project
Thanks alot....
