If you run an inductive load (such as a motor) make sure you include the diode in the circuit.

Think of the circuit as an on/off switch. You can control pretty much anything with one.

can i control motors with modified servo movement panel?

No. Using a TIP to control a motor would only allow it to move in one direction. It's either powered up or it isn't. If you want to control DC motors the correct way would be to use a H-Bridge and use the H-Bridge Movement Panel or PWM controls.

Depending on their size there are a few options available. All are covered in the tutorial pages.

to control TIP120/TIP122 Darlington switching circuit i just need to enter Set(d1,on) to turn it on and Set(d1,off) right?

thanks

Yes.

Or you can add a Set Digital control assigned to the correct port.

thanks rich can i get your e-mail if you dont bother giving it. it would be a lot easier to benefit from your knowledge

you can, it's [email protected] however questions like these benefit the community as someone may come and search for similar in the future and the answer is right there already.

okay i will try to write here as much as possible

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
