hi all,
what can i do with a TIP120/TIP122 Darlington switching circuit i think some people connect circuit to dc motors is it possible to run dc motors via TIP120/TIP122 Darlington switching circuit
thanks
Think of the circuit as an on/off switch. You can control pretty much anything with one.
Depending on their size there are a few options available. All are covered in the tutorial pages.
thanks
Or you can add a Set Digital control assigned to the correct port.
can i get your e-mail if you dont bother giving it. it would be a lot easier to benefit from your knowledge
while you are here i have another quick question i am making a robot which goes only forward it uses dc motors i know i can use h-bridges or brushed car esc's but i dont want to spend extra money i already have 2 20amp brushed esc's i will use them since they wont go back is it possible to write a code that will turn robot other then moving backwards thanks
I would spend the money on a H-Bridge to be honest, a TIP isn't really the right way to control a motor. You can pick up the TB6612FNG Motor Controller for pretty cheap, it's what I use in my robot. Just be wary of the maximum current it can take. If the motors are high power you will want something along the lines of the Sabertooth.
Code:
You may (however I do not know) be able to use the 4 wire HBridge movement panel. Left() and Right() set forward on the one side and reverse on the other, but with no reverse it should still turn. You just wouldn't have Trigger B and would need to set Left and Right Trigger B to unused ports. I have not tried that though.
I still wouldn't suggest running motors from a TIP though but it's your call. Just make sure you make the circuit right and include the diode to save yourself from breaking the EZB.
