Used the same unit and got a useful range of 200 feet using 12 volts on xmtr.

Re: What do you make with your stepper motors?
on: January 07, 2013, 06:09:56 pm
Used one to make a liquid stirrer using 2 magnets, one in a beaker one on the motor.
Also a linear actuator, CNC and an accurate coil winding device.

470uf ok but contains inductance, use a .1uF next to the audio cct.

The prototyping board has inherent capacitance + there is internal I.C. capacitance.

Also, connect the 2 blue power rails with a wire.

On some long SK boards there is no connection 1/2 way between the power rails. Move the power wires closer to the I.C.

Not that we don't trust you, would you take a picture of your setup.

Draw a diagram of the actual circuit as you see it on the board, or send us a good picture of the setup.

Get your meter out and check the resistances between terminals.
Then draw a diagram for yourself.

Incorportate it in the circuit, use a jumper or 1 ohm resistor if it is not needed.
