![]() want these to be as small/large as possible without hitting the hard stop Adafruit_PWMServoDriver pwm = Adafruit_PWMServoDriver (0x40, Wire ) // Depending on your servo make, the pulse width min and max may vary, you Adafruit_PWMServoDriver pwm = Adafruit_PWMServoDriver (0x41 ) // you can also call it with a different address and I2C interface #include #include // called this way, it uses the default address 0x40Īdafruit_PWMServoDriver pwm = Adafruit_PWMServoDriver () // you can also call it with a different address you want Note, in my code, the push button is connected to Pin 9. To make the servo movement easier to see, attach a servo horn with a piece of tape or a paper clip. With the SERVOMIN and SERVOMAX identified, you can then load the Adafruit example from here: Set the starting PWM to ("Potential MAX" - 30) and a smaller increment, go with "1" if you don't mind pushing the button 30 times as I did. The same goes for finding the MAX, start with the MIN, set increment to 20 until you hit a point where the servo no longer moves, this will be your "Potential MAX". So we set the initial value as 80 and cycle through with increment 1, this way we know the exact value for SERVOMIN. To fine-tune the PWM, Set the initial PWM = "Potential MIN PWM - 10", and change the increment from 5 to 1, then repeat the testįor example, with the initial PWM set at 70 but the servo only started to move at 85, we know the "Potential MIN PWM" is between 81 and 85.Program to increase the PWM by 5, then repeat the loop till your servo moves(This is your Potential MIN PWM).Drive the servo with this PWM when the push button is pressed, and display the value in Arduino Serial Monitor.Define an initial PWM ~70 (Googles says most of the servo PWM starts from 100 but mine somehow moves at 79).I have only a push-button module with me right now, I know how unbelievable it is, so had to work around that. I wanted an Arduino to do above for me semi-automatically.A maximum PWM that moves the servo to it the maximum range.A minimal PWM that moves the servo from the initial position.Here is how I understand it, basically all I need to do is to find Serial1.Their ideas and approach are brilliant but I do not have a "pot" right now and I do not want to spend hours writing and debugging a Python UI. After uploading the demo, connect the serial bus servo to the ST3215 serial bus servo interface on the driver board, connect the XH2.54 power supply interface to the power supply, and run the demo, you can see the servo will swing back and forth. Upload the demo after selecting the development board and the port. In Arduino IDE, click "Tools" → "Development Board" → "ESP32" → "ESP32 Dev Module". Click on "Tools" → "Ports", and then click on the new COM. After downloading, you need to extract it to the path of C:\Users\username\AppData\Local\Arduino15\libraries.Īfter downloading the zip package, open Servo.ino, connect the multifunctional driver board to the computer with a USB cable (here the Type-C port of the USB of the multifunctional driver board is plugged in), click "Tools" -> "Ports", and then click the new COM (COM26 in my case). The demo about how to easily control the servo is provided as follows.įirstly, you need to download the dependency library. ST3215 is a serial bus servo with large torque, and you can refer to the link to view it.
