Motor Shield Problem

Post by jomstudio »

Hi Everyone,

Ive just finished setting up the motor shield but I cant get it to work, if I plug in a servo it gives it a little push but shuts off in about 2 seconds.
The green light is off also. I check for voltage across the LED, Capacitors and all give me 9V. Any suggestions?

Post some photos of the front and back of the board and we will have a look for any assembly problems.

The photos are too blurry to see much.

You should not have 9v across just the led. Are you sure you installed it with the correct polarity?
I plug in a servo it gives it a little push but shuts off in about 2 seconds.
The servos run off the Arduino 5v supply. They should be powered as long as your Arduino is powered.

What are you using to power your Arduino?
What power source do you have connected to the external power terminals on the Arduino?

What is the power source you are using?
What is the code you are using?

As the tutorial says:
You can't run motors off of a 9V battery so don't even waste your time/batteries!
If you want to run from batteries, this is a much better choice: http://www.adafruit.com/index.php?main_ ... cts_id=248

What kind of motor?
What is your power source? Have you found something better than a 9v battery?
What code are you using?

Its a 6Volt DC Motor, using the motor test code with a AC to DC power supply plugged into the wall.

Does the motor make any noise at all?
With the program running, can you measure any voltage on the terminals for M4?
