HOOKING UP A SERVO MOTOR ARDUINO HOW TO

The Arduino Uno, the power supply or regulator is capable of about a maximum of 800 milliamps, no more and when it’s plugged into USB, of course, most USB ports are only good for 500.īut you also have to factor in the chip is going to draw some current - that microcontroller that powers the Arduino and you know, the little LEDs and stuff so you could get yourself in trouble real quick.

Now if I take this and grab it with my fingers and stop it and actually stall the motor that shoots up to about 430 milliamps. This is the horn it’s - called a horn, spinning around and I took some current measurements earlier of this setup right here and right now with no load it draws anywhere from sixty to a hundred eighty five milliamps, depending on where it is in that, you know, the position of where it is in the program. Motors can draw a fair amount of current and the more load of motor has the more current its going to draw and when a motor stalls - as in it too much load to can’t handle it, It’s trying and trying but just can’t do it - That’s when it’s going to draw the most current.Īnd we see this little thing here. But I do want to say a few things on Motors in general. I’m not going to go into a lot of detail about how Servo Motors work or anything like that. So I’m going to plug in the Arduino.Īnd we see it sitting around, 180 and reversing and doing another 180. So, we’re going to talk more about that in a minute, but I just want to demonstrate real quick what this does. Now, that may or may not be a good idea depending on the motor and what you plan on doing with it. We can see we have this this little servo motor here connected directly to the Arduino. And today I have another Arduino tutorial and we’re going to talk about using a Servo motor with Arduino. It’s Brian Jenkins with circuit crush TV.
