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 datasheey this would mean it would be able to saturate collector currents above mA, which is fine here. So 20 indeed is a positive supply voltage pin, as it’s labeled Vcc.

Is that the way to go? Project Would someone be interested why, I’m trying to control the solar panels at home to get them always at an optimal angle.

I use supply with internal control voltage I think, so the first image. Use fricking code tags!!!! Expected result There should flow current to the controller enable when the Arduino puts 5V on the transistor, and not so otherwise. NEW Library to make fading leds a piece of cake https: Now looking at the second picture, and there I can switch the connection to ground.

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

Android app included, hooray for ethernet shields. The circuits 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.

MarkT Brattain Member Posts: Possible problem points I thought about: If it doesn’t provide its own power you have to provide at least 12V externally and high-side switch it. Dafasheet the Arduino pin is low, I measure around 14 volts across both transistors, which is fine.

Oh, hang on a second. Transistor The first time I connected the transistor datazheet the base resistor, and I don’t think I’ve blown it but who knows So I’d need to figure out a 14V power supply TomGeorge Design and Repair of industrial control systems.

BC517 – BC517 NPN Darlington Transistor

Test code I’m sure there’s nothing wrong with that because I tested the output with a multimeter, 4. Where is the datasheet for this drive?

You’ll have to dataasheet out whether the digital section is opto-isolated with a multimeter. So since I want to switch the ground, I need to intercept the connection somewhere right?

Actual result Unfortunately the motor always starts when I connect the transistor, even if the base is connected to b5c17 Arduino ground. Thanks Tom, nice find, only one page further But now the motor doesn’t do anything Q1 is PNP transistor Tom MarkT on Jul 13, If its isolated and it provides its own power, you can very simply use an NPN to switch it.

Don’t try to switch the 12V, switch the GND and you are all set. PHPirates on Jul 13, Is it opto isolated?
