Hi guys,
I have recently started using an Arduino UNO board for a camera controlling project. I am just getting used to the code so forgive me if I've made some beginners errors!
I have uploaded one of the pre-loaded sketches within Arduino. File\Examples\Stepper\stepper_oneRevolution
This worked fine and was uploaded to the board sucessfully, but now I cannot seem to stop the stepper motor running other than removing the power supply. I have tried the Reset button which only appears to pause the motion, which then continues as the button is released. I have also tried holding the button and removing the USB which did not stop the motor from running when the power was plugged back in.
Also, I have notices that TX and RX are not responding to uploads as the lights do not come on. I would like some advice on how to stop a sketch from running and also how to upload a new file onto my UNO board.
When trying to uload a sketch on top of the code already present in the momory of the board, I get the error code:
avrdude: stk500_getsync () : not in sync: resp=0x30
Could somebody please tell me what this error means and how I might go about solving it.
Thanks a lot!
