Title: Resistor-mod of HS-311
Post by: Fleet on June 08, 2011, 09:41:39 AM

Hi,

When I built the $50 robot (mega8 1Mhz), I resorted to the glue method to modify the servos, but I can't help wondering why the resistor method didn't work for me. I used this loop:

Code: [Select]

while(1)
{
PORT_ON(PORTD, 0);
delay_cycles(27);
PORT_OFF(PORTD, 0);
delay_cycles(2000);
}

The problem is that I couldn't get the servos to stop, they would continue to drive around very slowly when using around 22-27 or 43 delay cycles depending on how the resistors were connected to the wires and the resistors' values. Has anyone else experienced similar issues? Do you have any ideas why I couldn't make the servos stop?


I made a thread (http://www.societyofrobots.com/robotforum/index.php?topic=13901.msg102729#msg102729 (http://www.societyofrobots.com/robotforum/index.php?topic=13901.msg102729#msg102729)) about this when I built the $50, but I failed to mention in that thread that I tried using different numbers of delay cycles and not only the hold_servo hex.
