| I found this circuit in my files. I don't know where it came from, but it looks like I photocopied it from somewhere years ago. I have been told that it came from "The Robot Builder's Bonanza", by Gordan McComb. Anyway, I thought that it should be fairly useful, so I decided to post it here. The circuit is very simple and inexpensive. This is good thing because most commercial stepper motor controller ICs are quite expensive. This circuit is built from standard components and can easily be adapted to be controlled by a computer. If you use cheap surplus transistors and stepper motor, the price of the circuit can be kept to under $10. |

| I need help on my project that is in stepper motor and streight gears | ||
| i want to control a stepper motor by PC through a parralel port and for this i need to the simplest interface circuit . the programs software which will be usefd are either turbo pascal or delphi | ||
| Well I made this too, but it isn't working. I have the same problem as @Santiago | ||
| Can the circuit be modified to drive a brushless dc motor? | ||
| this looks great. probably the cheapest driver i have found. thank you will use on my next cnc project | ||
| To Santiago: I am not try this circuit yet, but it seems it work. You must know: This is for Stepper Motor, if you want to try, just touch the step to the ground/zero a few times (on-off-on-off-on-off ...) it should make the motor move. If the motor not move in one direction, try to switch the coil connection (A to C or perhaps to B). Have a nice try.... | ||
| Hi!!can a high torque stepper motor be used to control a sequential gear box?Can you please assist me in this?Thanks | ||
| I want to have the motor go 90degrees up and 90 down on each cycle of a switch, will this be difficult. Would this be able to be via remote? | ||
| Hello, I built this circuit but it`s not working for me; when I switch on the power supply all the npn transistors get polarized and the stepper motor won't move, Can anybody help me? What am I doing wrong? thanks | ||
| Would this controller be able to operate a 5.25" disk drive reader motor to operate a model railway turntable. Cheers, Rod | ||
