There are other servo motors that are used for model aircraft building they are known to be more precise. This is not a micro servo like SG90 but it is more precise and it can also deliver more power.

You could use a better servo motor like “Tower pro MG 995” servos. There are a couple of fixes available online for this overshoot/undershoot problem. This is when the servo motor exceeds the specified degree and sweeps more area than it is supposed to do. This causes the situation to “overshoot”. Whereas those systems that are underdamped go over the target. This means, the servo would not really reach 0 to 180 degrees or other specified value. In general, we can say, the systems that are overdamped miss the target value, that causes the “undershoot”. This is a problem has a bit to do with Control Systems. There is a common problem when dealing with SG90 (or even MG90S) that is the overshooting or undershooting. The overshooting/undershooting problem with SG90s So when we use an external power supply, it will make sure that the Arduino board won’t be damaged due to excess current draw. The maximum current draw from Arduino is 0.8A only. It is recommended that the servo motor should be powered externally (using a dedicated power supply) and the voltage should be within the accepted range. This servo motor has input voltage of 4.8V to 6V DC. But it is important to keep in mind that the motor should be powered separately. You can find the following electronic components in our website.įor demo purposes, with zero load on the servo motor, we are powering the servo motor using Arduino 5V pin. This project uses SG90 servo motor interfaced with Arduino Uno which is programed to turn the servo motor from 0 degrees to 180 degrees and back to 0 degrees.

We can use Arduino IDE to code this servo and control its movements precisely. SG90 is a lightweight (just 9g) and tiny servo motor which has quite good output toque. This is actuator interfacing with Arduino Uno and the actuator being servo motor, specifically SG90 servo motor. Let’s take a look into a simple interfacing project this time.
