![]() The following code will turn a servo motor to 180 degrees, wait 1 second, then turn it to 0, wait one more second and then repeat the process. We can control the servo motor by utilizing the Servo.h library, which is already included in the Arduino IDE upon installation. While the duration of the pulses required to control a servo motor is typically standardized, the minimum and maximum pulse durations may vary depending on the specific brand or model of the servo motor being used. Generally pulses with 1ms duration correspond to 0 degrees position, 1.5ms duration to 90 degrees and 2ms to 180 degrees. The width of the pulse is what determines the angular position of the servo, which can typically rotate up to 180 degrees, as it has physical limits. A servo motor is controlled by sending a series of pulses through the signal line. Once the servo motor is connected, the Arduino Nano can send pulse signals to the servo motor to control its position. The servo motor's power and ground are also connected to the power and ground pins on the Arduino Nano, respectively. To connect a servo motor to Arduino Nano, the servo motor's control line is connected to one of the PWM enabled digital pins on the Arduino Nano. The length of the pulse determines the position of the servo motor. The servo motor's position can be controlled by sending a pulse signal to the servo motor's control line. The connection between Servo motors and Arduino Nano is straightforward. The choice between the two will depend on the specific requirements of the application. This means that the MG90S is more responsive to changes in position or speed, making it better suited for applications where fast and precise control is necessary. The SG90 has a response time of around 0.12 seconds, while the MG90S has a response time of around 0.08 seconds. The metal gear train makes the MG90S more durable and able to handle higher loads than the SG90, which may be prone to wear and tear over time.įinally, the SG90 has a slightly slower response time compared to the MG90S. Additionally, the MG90S has a metal gear train, while the SG90 has a plastic gear train. This means that the MG90S can handle slightly higher loads than the SG90. The SG90 has a torque of around 1.8 kg-cm, while the MG90S has a torque of around 2.2 kg-cm. The SG90 is a smaller and less powerful servo motor compared to the MG90S. The SG90 and MG90S are two popular models of servo motors that have some key differences in their specifications and performance. They are typically more expensive than other types of motors, such as stepper motors or DC motors. ![]() ![]() Servo motors come in a range of sizes and shapes, from small motors that can fit in the palm of your hand to larger motors that can power industrial machinery. 1x Arduino Nano ( or another Arduino module)Īvailable on: Ebay | Banggood | Aliexpress
