What advice can you give me? Ive tried a digitalWrite command, and a PWM.
Engineering is based on numbers – not adjectives Billy Robot Overlord Posts: MeckelBot on April 17, The resistor is, still, between base and the digital pin. Click here to register now. Soeren, im very, very thankful for all your patience and help.
Login or Register as new user free if you want to see more distributor details. That’s why you should always test peripheral stuff on its own before hooking it up to a controller. D transistor datasheet request. Analog pins are input and as such high impedance, so it will act like the basis is floating.

Over time, you tend to get some preferred components for sub circuits like this, since you cannot stock all components and it’s cheaper to buy and stock a few selected types, so for that reason, I have around pcs of the TIP and of the TIP Fourteen year old thread. April 22, If the pinout is equal to the TIP post the name of d133 actual transistor you gotyou couldn’t have gotten it more wrong.
Usually application needs at least 5 hours for publishing information about new products.
choosing the transistor?
So, i have one end of the battery pack connected to the motor. The green wire from the motor goes to the middle pin of the transistor. You may have killed the transistor if you have connected it wrong at an earlier attempt. With such high gain, even touching it with as finger may turn it on and the piece of wire act like an antenna, catching any electrical fields near it. D is common and TIP transistors are hard to find. Don’t hold the soldering iron on any pin for more than a few seconds 3 seconds max.
Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. I went to a couple of stores here, but just by telling them what I wanted, they couldnt help me. Get Your Ad Here. What I have right now is screwing at least one of my basic ideas on how this whole thing works. Sounds right to me, but just in case, here’s a schematic and some pics Add a diode across your motor terminals so you don’t destroy the transistor or your uC.
This rise can be suprisingly large. You need an output pin to control it. Replacement Transformer Started by ncag Today at 7: The emitter of the trans is also connected to the GND of the board.
Its kinda late and my energy source of the motors are two battery packs which i tried to “add”, and i have no idea in the end which becomes positive or negative, which i dont think is the problem, but just adds confusion to my head.
Imagine that this responsive data-sheet is included in the product page of your webshop. Thanks, and sorry for all the newbie hassle. Alright, so that got the motor spinning. The diode will clamp the voltage to less than a volt and greatly increase reliability. Logged Soeren Supreme Robot Posts: Potentiometer Questions Started by norbss Yesterday at My bad, i meant digital Pin.
Be careful how you solder it and use heat shrink tubing or tape if needed, to make sure you don’t make any short circuits. To datashete you need to register. More Sharing Services Share.
