But is there even a difference in powering the Arduino via USB and connecting the servo to the VCC of the Arduino? Is it a problem to connect GND and UGND? I removed the mechanical stop and replaced the pot with a voltage divider.
I thought it would be a nice and easy solution to power the Arduino using a USB power supply and to cut the USB cable and connect the servo directly to the +5V of the USB. So I recently hacked a 5V hi tec HS-322HD servo to produce continuous rotation. Sketches include a precision control for a servo motor and a tachometer for a DC motor. Is this correct or does this apply only to the digital out pins? Would it be better to power the servo using an external power supply? From Raspberry Pi to Arduino to drones, Tindies goal is to bring. The multimeter shows that it draws up to 0.6A which is about 10 times of what I'd expect that the Arduino can provide. Then the loop, which consists of two for loops. Brown connects to the ground of the Arduino. In the setup we attach our servo object to the servo motor control line on pin 9 of the Arduino. Pololus Maestro servo controllers offer industry-leading resolution and stability. But I am a bit worried if this is a good idea. The servo connector has three wires - Brown, Red and Orange. It seems to work fine when I connect it directly to Arduino's VCC, GND and an PWM pin. I want to use a servo motor and control it by an Arduino Duemilanove (or a Leonardo).
