Low Power / intensity in board CHI035A, PICAXE 18M2 ( SOLVED )
December 8, 2012
So I have this setup:
What is written at the end of the orange lines are the ports of a bluetooth module, and the ports 0 and 2 in the board are the respective input and output non-buffered ports.
What I'm trying to accomplish here is a robot that follows orders sent from an Android terminal through a bluetooth connection, using a bluetooth module. The robot has two motors to move around the floor or wherever you put it.
All the bluetooth part receiving and sending data with the Android is solved and works well, but I have some consistent problems now with the power in the board, more concretely the motors.
The motors are these : http://www.pololu.com/catalog/product/61/specs
I also have a buzzer connected to the board, with which I do the testing with the bluetooth although it sounds very weak. The motors, in place of moving or showing any sign of life, the only thing they do is some kind of sharp sound whithout moving.
At first, everything worked fine, the motors worked as they should, but progressively they have stopped working because of unknown reasons.
I have tested the motors with the batteries, connecting them directly, and they work properly, but when it comes to use them altogether with the board, they just don't work.
