The other comination such as AB,AC, AD,BC,BD etc gives 50 ohms in multimeter. When you turn on a single switch, the motor lines up the rotor with the active pole piece in the stator. Soon, the first signs of frustration appeared. Motor should have gone through one stepping cycle. If you had that type (consult the manual for that board), you would tie ENABLE to the inactive power plane (ground or +5), set DIR to a SPDT switch, allowing you to drive the signal with +5 or ground, and then drive the STEP input with the frequency waveform generator (or 555 output) simulate this circuit Schematic created using CircuitLab. Then take the yellow wire and connect it to the black probe. The multimeter will not beep in this case because you are using a different combination of wires for each coil, which can produce a reading if they were both attached at one point on their respective sensors (like when fishing). Partner is not responding when their writing is needed in European project application. General - Connectors on Step Motor Cables? But I think it's possible to rotate it may be very small angle without a microcontroller. I wanted to achieve a clear simple representation and differences between the individual modes. Now turn on switch 1. Your Ohm measurements don't add up. First I measured the internal dimensions and then I cut a rectangle out of hard cardboard, which served as a template for the placement of components. If the flashing speed of the LEDs corresponded to the motor windings, we would see it as a continuous illumination of all of them. There is no polarity so it doesnt matter which probe goes where. . Next, adjust accordingly by pinging them together until readings show up correctly; note these numbers below.Suppose you are getting readings that range from 0.0 ohms to 1.0. The red light will indicate how many Ohms are in total between both connections, with lower numbers meaning better connectivity for optimal performance. While holding the probe on one pin, move it across all other pins stepwise. Upper part of the diagram describes the power supply - a 12 volt adapter, which is reduced to 5 volts by a linear regulator.
