It should be noted that all IO pins in Wemos except D0 and A0 support pwm, so you can extend this project to a large number to control more servers. Make the connections according to the schematic and the table below. In this case, we will use pin D4, but you can change this part according to your interest and needs by changing a part of the code. In this project, we will use one of the pwm pins of ESP8266 board to start the SG90 servo motor. By changing the slider values from 0 to 180 we will be able to control the servo motor connected to Wemos D1 Mini. We can also customize the page as needed, where we have a slider to change the pwm values. In this project, we first run a web server on port 80 using the Wemos D1 mini board, which uses the ESP8266 chip. For example, if the Duty Cycle of a PWM wave is equal to 80%, that is, in each cycle 80% of the voltage is equal to 5 volts and 20% of the voltage is equal to 0. In fact, pwm is a square signal that can be 1 or 5 volts at a time, or 0, which means 0 volts. Pulse Width Modulation or pwm, a way to regulate electrical power by changing the cut-off time and the connection of the source in each cycle. Servo motors are classified into different types based on their application, such as AC servo motors and DC servo motors. This feature allows servo motors to rotate with great precision. This type of motor consists of a control circuit that provides feedback on the current position of the motor shaft. Materials RequiredĪ servo motor is a type of motor that can rotate very accurately. In short we will learn about Wemos D1 Mini Web Server based Servo Motor Control. Also it will control the amount of rotation of the desired servo motor. We will be using a web server run by our Wemos board and we will be able to measure the pwm. In this tutorial, we are going to do this differently. So far, we have generated the pwm signal in various ways and thus controlled the servo motors.
