another $50 robot question
« on: March 20, 2010, 04:16:03 AM »
I just finished the $50 robot tutorial and although I don't have a cable to connect to the computer but I'm confused about the LED. Is it supposed to light up when the power is connected or did I miss something along the way?
It looks like the LED resistor is hooked up to a pin on the mega8 so i was wondering if that is on when it's connected to the PC.
Any help would be appreciated

You must program the microcontroller for the LED to turn on.

like the post above,yes.the command i think was LED_on() and LED_off()
to test,put this in the "main"under /*********ADD YOUR CODE BELOW THIS LINE **********/

Code: [Select]
while(1);
{
LED_on();
delay_cycles(23);
LED_off();
delay_cycles(23);
}
this will cause your led to turn on for 1 second ,then turn off for 1 second ,and so forth until you turn it off
simply replace the code or just add LED_on() at the beginning of your photovore code,replacing the LED_off()

i hope this helps!
