MarkT Brattain Member Posts: Use fricking code tags!!!! You’ll have to find out whether the digital section is opto-isolated with a multimeter. Oh, hang on a second. So 20 indeed is a positive supply voltage pin, as it’s datassheet Vcc. Actual result Unfortunately the motor datashee starts when I connect the transistor, even if the base is connected to the Arduino ground.

If it doesn’t provide its own power you have to provide at least 12V externally and high-side switch it. So since Datasneet want to switch the ground, I need to intercept the 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.

I use supply with internal control voltage I think, so the first image.

Hi, This is what you are looking for. Is it opto isolated?

Transistor The first time I connected the transistor without the base resistor, and I don’t think I’ve blown it but who knows MarkT on Dstasheet 13, I just bought some PNP transistors and made a high side switch now, using a circuit for example from Stackexchange.

Is that the way to go?

Now looking at the second picture, and there I can switch the connection to ground. Project Would someone be interested why, I’m trying to control the solar panels at home to get them always at an optimal angle.

If its isolated and it provides its own power, you can very simply use an NPN to switch it. Where is the datasheet for this drive?

BC – BC NPN General Purpose Transistor

When the Arduino pin is low, I measure around 14 volts across both transistors, which is fine. We also replaced the transistor just in case it was broken, and tested some other crucial connections, although not all. Everything runs on smoke, datashfet the smoke out, datasheet stops running Test code I’m sure there’s nothing wrong with that because I tested the output with a multimeter, 4. Sorry for the bumping, but I just measured some things.

PHPirates on Jul 13, Expected result There should flow current to the controller enable when the Arduino puts 5V on the transistor, and not so otherwise. The circuits look similar, although they use an extra diode because of the dc motor and the motor is on the other datasheeet of the transistor, which I think shouldn’t matter.

Possible problem points I thought about: Android app included, hooray for ethernet shields. Thanks Tom, nice find, only one page further 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.

Q1 is PNP transistor Tom NEW Library to make fading leds a piece of cake https: Don’t try to switch the 12V, switch the GND and you are all set. So I’d need to figure out a 14V power supply
