Servo Motor Control Issues

I've connected a servo motor to my arduino boad, (Elegoo 2560), and have been trying to cuse simulink to run the motor. Ideally I would like it to spin when an input is recieved, but I can't make it spin at all for some reason. Attached are the simple set ups I've been trying to run, but I keep getting the error 'error building' with no details. Is there a visible reason for this error, or something I should change?

Hi Benjamin,

I understand that you're trying to control a servo motor connected to an Elegoo 2560 (which is compatible with Arduino Mega 2560) using Simulink. Your goal is to have the servo motor spin when a specific input is received. However, you're encountering an issue where you receive an 'error building' message without any further details during the process.

I can provide some general advice on troubleshooting your problem;

1. Check the Hardware Connection: Please ensure that your servo motor is properly connected to your Arduino board. The servo has three wires: power (usually red), ground (usually black or brown), and signal (usually yellow or white). The power should be connected to a 5V pin on the Arduino, the ground to a GND pin, and the signal to a digital pin.
2. Check the Simulink Model: Please make sure you're using the correct blocks in your Simulink model. You should have a "Servo Write" block from the Simulink Support Package for Arduino Hardware, and this block should be connected to the correct pin on the Arduino board.
3. Check the Arduino Board Configuration: In the Simulink model, double-click on the "Hardware Settings" block and make sure that the type of board (Elegoo 2560) and the COM port are correctly specified.
4. Update Firmware: Please ensure that the firmware on your Arduino board is up-to-date and compatible with the Simulink Support Package for Arduino Hardware.
5. Check for Compilation Errors: The 'error building' message suggests that there might be a problem compiling the code generated from the Simulink model. Please check the MATLAB Command Window for any error messages that might give you more information about the problem.

Please refer to the following MATLAB documentation to know more about Simulink Support Package for Arduino Hardware:

Hope this helps.
