Okay, I’m stuck. I don’ t know what I’m doing wrong or what I need to do next. So, I’m calling upon John Abella, Sandy Noble, and Kongorilla for your help. :)
Here’s where I am:
- The burning!
- At last attempt, I hooked up some small steppers to the Adafruit motor shield, put the shield on my Arduino Uno, hooked up the USB cable and the 9v power adapter.
- I heard a small pop and smelled warm electronics.1
- After the burning
- I can upload and run the Arduino basic blink sketch. I can alter this to change the blinking pattern.
- I can upload and run the Arduino sketches to operate a microservo. I can alter this to change the microservo’s behavior.
- I can upload the Adafruit sketches for steppers – but I can’t make the steppers move.
- I can upload the Polargraph sketch – but I can’t make the steppers do anything.
- I am connecting the steppers to the shield according to the instructions on the Adafruit page: “To connect to our shield, put the wires in this order: Red, Yellow, skip ground, Green, Brown“
- When I connect the 9v power to the Arduino, all it does is make the two chips on the Adafruit motor shield very warm.
Now, I’ve got tons of questions for you:
- Did I ruin my Arduino? I can still run the blink and microservo sketches.
- Did I ruin my motor shield? How can I tell if it is operational? When I connect the power to the Arduino and have the little jumper in place, the green LED is lit up.
- What am I doing wrong?
- What should I try next?
- How should I diagnose a problem?
- Now I’ve got a cold and couldn’t smell anything if I wanted [↩]
