![]() If you just have a "defect" 180 degree servo turning to lets say 190 degree for some reason, you might try the microsecond method playing around with the values in attach, also use an extra power supply, but for real over 180 degree action get a 270 degree servo. servo.attach(5,500,2500)ĪND you have to use an extra power supply for 270 degree servos, the 5V from Arduino want make them move or only in a jittering way of. If you want to control it more precicly you use microseconds. So if your servo is a 270 degree servo (like the domanrc DM-S0903MD or DS3218 270 Degree Digital RC Servo) the standard sweep sketch (Arduino Servo library) will let your servo sweep from 0-270 even if in the *.ino its myservo.write(180) So to simply test you could use write(map(desired_angle, 0, 270, 0, 180)) You can bring it to rest at any angle you desire by adjusting the pulse width accordingly. #Servo motor arduino turning a wheel fullVarying the pulse width between 1ms and 2ms will move the servo shaft through the full 180 degrees of its travel. Each wheel is attached on a NEMA 17 stepper motor, and knowing the fact that stepper motors can be precisely controlled, I added one more cool feature in the app through which we can program the robot to move automatically.
