G+_Joseph DuPree Posted January 20, 2018 Share Posted January 20, 2018 Need a little help I, my son and I are trying to build a robotic arm. I 3d printed the parts to make a robotic arm and I purchased servos, Arduino Nano, and a shield to finish the project. But I am unsure how to access the Servo with Arduino. I tried one using the canned sketch in the Arduino IDE. But I can not seem to get it the work. I am trying to go through the shield to operate it. I probably got the wrong shield, it’s a sensor shield. Thanks Link to comment Share on other sites More sharing options...
G+_Ben Reese Posted January 20, 2018 Share Posted January 20, 2018 Mind sharing a link to the servo and shield you're using? Link to comment Share on other sites More sharing options...
G+_james robinson (radiati Posted January 21, 2018 Share Posted January 21, 2018 Depends on the size of the servos. Small hobby servos don't need a shield, you can power them from the 3 or 5 volt rail, and drive from any output. You may need an external power source for larger servos. You really only need a shield for brushless or stepper motors Link to comment Share on other sites More sharing options...
G+_Joseph DuPree Posted January 22, 2018 Author Share Posted January 22, 2018 the servo are tower pro sg90 and the shield is a tiny I\O sensor shield. Link to comment Share on other sites More sharing options...
G+_Roy Z Posted January 25, 2018 Share Posted January 25, 2018 Check this tutorial out. Use a separate power leg for the servos and be sure the grounds are shared. I used this to check out a small pan /tilt unit. Just added a second servo (myservo1) in the code connected to pin 10. arduino.cc - Arduino - Sweep Link to comment Share on other sites More sharing options...
