Ok hoping you can answer this one question for me.Is a motor driver and a motor driver shield the same thing, y do they use the word shield? Just curious for future endeavors.
"Motor Driver" refers to a function. Electronics to help your micro controller control your motor(s). “Motor Shield” is a specific product. It contains a motor driver. The word “shield” is used in the Arduino world. This tutorial lives in a different world: Picaxe.
The driver here is a chip with 8 pins called L293D. It sits directly on the Picaxe project board. Compare the Arduino where a motor driver is (often) a separate board (which is called a shield). That board could also use this chip. Or any other circuit or IC that contains an H-bridge.
What do you mean by “cannot function”? What are you trying to accomplish, what do you expect, what are you seeing, what did you try to solve this so far, did it help?
These are all questions you need to answer or we cannot help you without guessing.
What does your debug say gnipna? if you did the readadc 0 ,b0 it’ll tell give you numbers try it right up to b10 if you have too
And Fritsl thanks for the update on the code T.E.D.D aka tedious electrical dip sh** device is up and running like a good 'un
still getting low readings from the sharp running about 16 - 17 max on the debug could be my soldering slash and or wiring but with changing the code to suit he seems to know vaguely what he’s doing apart from close up to objects. wonder if i add some more subroutines in for lower readings if that would affect it much? seems when my fingers or an object are over the sharp it reads a zero and he was having the occasional problem with getting to close to a chair or a cup and deciding to move it with his head, good move for a larger robot not so good with a diddy one anyone have any thoughts on that ?
No matter what program I upload, all that happens is the servo twitches. The wheels won’t move, and the servo won’t turn properly. If I upload a program with just the motors in it nothing happens. I checked that I did everything like the tutorial.
I have no idea what to check now and I’m really frustrated. Any ideas what could be wrong?
Can I make this robot beep without giving up the servo?
Firstly, thanks so much for this tutorial fritsl!!! Couple of us have had a blast throwing this together and watching him come to life. I’m just wondering if there’s anyway to make this robot beep as is, without giving up the servo?
