Hi ..

I wrote the following code in Keil for a 89s52 and downloaded it to the chip..

It is only for the bot to move straight..I am using a L298HN ..the code ompiled successfully .. But the bot does not move .. I am getting a voltage reading of 3-4 volts at the Port 2 pins .. PLzz help me out ..

void gofor();
