Rotation angle is something like between 260 and 270. Will write more later about the reliability.
Hi, how to make the servo run every step at 10 instead of 1 in the sweep sample sketch? see here: http://www.dfrobot.com/foru...
JaneYu can you give us the code in Arduino program for controlling this servo. Because i want to control it from 0-270 degree.
JaneYu Sure. I 3d printed a 2 cm length arm, mounted it on the metal servo horn, which is included.
Connected hand weigher to this arm, fixed the weigher in the way to pull servo arm with 3 kgs, after that sent signal to servo to rotate, and maximum weight that weigher shows is 4.2-4.6 kgs, which is equal to 8.4-9.2 kg*cm
JaneYu Just purchased this servos. Made my own measurements. Actual torque on 6 volts is only 8.5-9 kgs, not 13.5 ...
The quality of the servo seems to be good ... But the torque is less than promised ... I'm very upset and disappointed ...
JaneYu I'm assuming you can just do myservo.write(270)? Or do you have to use the myservo.writeMicroseconds(2500)? And i'm also assuming you have to code myservo.attach(9,500,2500) so the constructor can use this servo's specific pulse width?
JaneYu I am apart of Ftc team 535 and i have a question i cant seem to get answered anywhere. We recently purchased two 270 degree servos from dfrobot and i cannot get them to work in their full range. If i declare them as a standard servo object i can reach angles from 0 to 180. I was inside of the index and i found code for pwm controllers but i could not get them implemented for the life of me. If i could get some help it would greatly be appreciated.
JaneYu Hi, arduino library will have a limit for the range, you need to make some modify in the library, or you can send the pulse signal directly with "myservo.writeMicroseconds(1500); // set servo to mid-point" command. The pulse range is from 500~2500us (maps 0~270 degree, I tested, the real range could arrive 250 degree). You can check this page for some reference: https://www.arduino.cc/en/R...
