Pins 9 and 10 control the stepping method half or full steps. This is necessary because the pulsout command requires a pulsewidth in micro-seconds, not milli-seconds. 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. Notice that I added an extra step; taking the defined “delay” value and multiplying it by 1, A pinout for the UCN is shown in Figure 8. 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.

Well okay, I scanned the instructions that came with the “kit”, this is all I have had to go on, I did download a PDF on the b http: RBeersJr on Oct 05, You cannot use 6V, due to the draw of the motor. 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.
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.
The UCN can support voltages up to 35V. That’s where I would start. Two outputs are needed; one to control the step input pin 11and one to control the output enable pin 15 which enables the stepper motor while high and disables the stepper motor stepprr low.
Two or three hours spent thinking and reading documentation solves most programming problems. The sketch you have written, it requires a push button connection to arduino pins 9, 10, 11 are the pushbuttons N.
stepper motor – What has happened to the UCN? – Electrical Engineering Stack Exchange
This can stepper accomplished with a very simple program such as the following: I am trying to figure out how I can connect this to an Arduino Uno R3, any suggestions? This Simple Stepper Program should be suitable for testing. Not only does it allow for the control of more motors, but more importantly, it simplifies the process. This is necessary because the pulsout command requires a pulsewidth in micro-seconds, not milli-seconds.

The datasheet to the driver translator http: Robin2 Yes your are correct as the Drawing indicates a 6 wire unipolar motor PM version, B pin 14 is direction with reference to ground, and pin 11 is the step in-put, from the NE pin 3.
Notice that I added an extra step; taking the defined “delay” value and multiplying it by 1, Notice in the schematic that steppe resistors, rx and ry, do not have an assigned value. Additionally, you can switch between full and half stepping in real time via a switch on the UCN or you may have the PIC control itas well as reverse direction. You now only have to output the pulse of your desired speed.
This is because our motor draws only mA, well under the chip’s supported 1, mA. The motor spins and by adjusting the pot i can increase atepper decrease speed. I assembled the kit according to the drawing.
R Stepper Motor Basics. Figure 9 Notice in the schematic that two resistors, rx and ry, do not have an assigned value.

There is a wiring diagram on page 5 of the UCN datasheet. The schematic we will build steppdr use this chip is shown in Figure 9.
I would like to connect this to my controller and try to write the program so the motor moves specific degrees. 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. All the program has to do, is output a pulse and set the output steppfr low. RBeersJr on Sep 29, 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. Robin2 Brattain Member Posts: Ill try and draw it out and scan it post it a bit later. You also need to connect the Arduino 5v and GND.
