RBeersJr on Sep 29, , There is a wiring diagram on page 5 of the UCN datasheet. Pin 14 controls the step direction. Assuming you have a 6-wire stepper motor The motor spins and by adjusting the pot i can increase or decrease speed. This can be accomplished with a very simple program such as the following: Please post a link to the datasheet for your kit – especially for the stepper driver.

Ill try and draw it out and scan it post it a bit later. You can make the code even smaller by removing lines 1, 3, and 4 and replacing “delay” in line 5 with a set number in microseconds. That’s where I would start.
However, if you were to use a motor that draws the maximum or above, then you would need to use rx and ry to get the amperage under 1, mA. A pinout sfepper the UCN is shown in Figure 8.
The stwpper we will build to use this chip is shown in Figure 9. Please post a link to the datasheet for your kit – especially for the stepper driver.
The datasheet to the driver translator http: Notice in the schematic that two ste;per, rx and ry, do not have an assigned value. The motor spins and by adjusting the pot i can increase or decrease speed.
The UCN can support voltages up to 35V.
Figure 9 Notice in the schematic that two resistors, rx steppee ry, do not have an assigned value. R Stepper Motor Basics. Notice that I added an extra step; taking the defined “delay” value and multiplying it by 1, You also need to connect the Arduino 5v and GND.
This can be accomplished with a very simple program such as the following:.
stepper motor – What has happened to the UCN? – Electrical Engineering Stack Exchange
The sketch you have written, it requires a push button connection to arduino pins 9, 10, 11 are the pushbuttons N. I assembled the kit according to the drawing. Pin 14 controls the step direction. Assuming you have a 6-wire stepper motor There is a wiring diagram on page 5 of the UCN datasheet. You cannot use 6V, due to the draw of the motor.
Both of these controls can be manipulated by the PIC, but it is easier to control them directly through the use of jumpers acting as switches. Not only does it allow for the control of more motors, but more importantly, it simplifies the process.
This is because our motor draws only mA, well under the chip’s supported 1, mA. This is necessary because the pulsout command requires etepper pulsewidth in micro-seconds, not milli-seconds.

RBeersJr on Sep 29, You now only have to output the pulse of your desired speed. Additionally, you can switch between sepper and half stepping in real time via a switch on the UCN or you may have the PIC control itas well as reverse direction. I recently purchased a unipolar stepper motor kit from elexp.
Two or three hours spent thinking and reading documentation solves most programming problems. Robin2 Brattain Member Posts: Well okay, I scanned the instructions that came with the “kit”, this is 8504 I have wtepper to go on, I did download a PDF on the b http: I am trying to figure out how I can connect this to an Arduino Uno R3, any suggestions?
The UCN 5804 Stepper Motor IC
However, I prefer to the method shown in the listing, because it makes it easier to change the delay parameter in the more familiar milliseconds without having to convert it to microseconds. Figure 8 The schematic we will build to use this chip is shown in Figure 9. Pins 9 and 10 control the stepping method half or full steps.
