PHPirates on Jul 13, Don’t try to switch the 12V, switch the GND and you are all set. Use fricking code tags!!!! So I’d need to figure out a 14V power supply Is that the way to go? Is it opto isolated?

So 20 indeed is a positive supply voltage pin, as it’s labeled Vcc. The datashert look similar, although they use an extra diode because of the dc motor and the motor is on the other side of the transistor, which I think shouldn’t matter. When the Arduino pin is low, I measure around 14 volts across both transistors, which is fine. Possible problem points I thought about: Thanks Tom, nice find, only one page further Where is the datasheet for this drive?

If its isolated and it provides its own power, you can very simply use an NPN to switch dqtasheet. NEW Library to make fading leds a piece of cake https: But now the motor doesn’t do anything Transistor The first time I connected the transistor without the base resistor, and I don’t think I’ve blown it but who knows Q1 is PNP transistor Tom Expected result There should flow current to the controller enable when the Arduino puts 5V on the transistor, and not so otherwise.

MarkT Brattain Member Posts: If it doesn’t provide its own power you have to provide at least 12V externally and high-side switch it. Project Would someone be interested why, I’m trying to control the solar panels at home to get them always at an optimal angle. So since I want to switch the ground, I need to intercept datasheeet connection somewhere right?

Base resistor I calculated the 4K7 value with help from this post and otherswhich led me to believe that with a 5K resistor I’d get a base current of 1mA, which with a gain of I checked the datasheet on this would mean it would be able to saturate collector currents above mA, which is fine here.

Hi, This is what you are looking for. Now looking at the second picture, and there I can switch the connection to ground.

Actual result Unfortunately the motor always starts when I connect the transistor, even if the base is connected to the Arduino ground.

Sorry for the bumping, but I just measured some things. Android app included, hooray for ddatasheet shields. MarkT on Jul 13, TomGeorge Design and Repair of industrial control systems.

BC517 – BC517 NPN Darlington Transistor

I just bought some PNP transistors and made a high side switch now, using a circuit for example from Stackexchange. We also replaced the transistor just in case it was broken, and tested some other crucial connections, although not all.

Everything runs on smoke, let the smoke out, it stops running Circuit Of course I’ve googled around a lot, and found a lot of examples to control a dc motor with a transistor like this. I use supply with internal control voltage I think, so the first image.
