So I've finished the 50 dollar bot. Let me give you a run down on the issues I have at the moment.
I initially connected the programmer, and successfully programmed my Atmega 8. (The circuit is done exactly how it is explained in the tutorial.
So I crossed my fingers, connected the sensors and the servos. and plugged in my 6V Ni-Mh battery.
The servos started moving and changed direction for a couple of seconds and then slowly came to a stop. It sounded almost like it was runing out of juice. The servos then came to a complete stop.
I didnt buy servos that required modification, They were called continuous servos with a 360 degree angle of operation. Would anything need to be different in terms of programming for this?
Anyway I checked the voltage and it still read 6.45 Volts. Everything seemed to be connected appropriately, and voltages distributed well.
Something appears to have happened however, as now when I connect the programmer and I try to re-program the chip, I get an error. The servos also do not move at all.
Anyone give me an idea as to what is happening? Or could i get some more info on a way to find out what is wrong?
I am definately getting changed pulsewidth in accordance with the photoresistors. (Measured in Hz) One photoresistor doesn't seen to have an effect on the width.
Thanks in advance guys,
Oh and a special thanks to all those who helped write the 50 dollar robot tutorial
