Hi, this weekend i bought a K8055 USB kit to improve the control side of a small coil winding jig. I have a degree in software engineering so a board that enables me to use computer based logic to control electronics was perfect! I constructed the project without any problem. Once constructed i opened up the control application, ran the output test and marvelled at the flashing LED’s. I then tested the outputs with my multi-meter and got the expected results. It was at this point i thought all my problems had been solved… How wrong i was.
Moving on i connected up a small 5v motors to the PWM output and got nothing… so i connected it to the analogue output and again nothing, i tried my multi meter on the analogue output and got a variable voltage, so i thought the USB wasnt outputing enough power so i attached an external 5v supply as described in the manual, again nothing. So i tested the motor directly from the PSU and it ran a dream. So i started to wonder if the motor was to large… thinking such i connected up the smallest motor i have (a mobile phone vibrator) and again nothing.
So i searched on google to see if anyone else had a similar problem and found a reply on this forum which states that the 8055 will not control motors… i was agasht to say the least, the only reason for my buying of the kit was for the 2 PWM outputs which were to control the 2 small motors needed for my experiment. Once i was over the shock i began to look for an easy solution to this problem and found nothing that wasnt too expensive, in american or extremely complicated. I know my electronics knowlage is somewhat limited but i had hoped this board would allow me to increase my experience.
Can someone please tell me of a quick, easy and cheap solution to enable this board to control 2 motors?
Many thanks in advance
