Keyestudio IoT Smart Home Kit for ESP32

1. Description

As the rapid development of the Internet grows, various intelligent devices are gradually integrated into our daily life. For example, we can use RFID to open the door. In addition, the kitchen is equipped with a gas detection alarm, which alerts people to the danger when dangerous gas and large smoke are detected. When it detects rain, it can automatically collect clothes and close windows. All kinds of electrical equipment can be controlled by mobile phone, control lights, fans, air conditioning and so on.

In this connection, we seek to launch this smart home product with ESP32 control, which has a host of sensors and modules as well as networking function, making the relevant knowledge of the Internet more accessible to you.

Red line	5V
Orange line	GPIO5

⚠️ Especially Remind: The following two methods can be chosen freely according to your own situation.

Method 1：Arduino code

⚠️ Special note: Before you write the code and upload it, you must install the Arduino IDE, please go to the link: 5. Arduino Tutorial <https://docs.keyestudio.com/projects/KS5009/en/latest/docs/Arduino/arduino.html>__\ ，and then to see the part of 5.2 Getting started with Arduino .

How to get the code ?

In folder …\Resource compression package\arduino Code , open file Initialization-of-window-servo-angle.ino , or copy and paste the following test code into the Arduino IDE.

#include <ESP32Servo.h>
Servo myservo;
#define servoPin 5

void setup() {
  myservo.attach(servoPin,500,2500);
  myservo.write(0);
  delay(300);
  myservo.write(90);
  delay(300);
  myservo.write(0);
  delay(300);
}

void loop() {
  // put your main code here, to run repeatedly:
}

Method 2：MicroPython code

⚠️ Special note: Before you write the code and upload it, you must install the MicroPython IDE, please go to the link: 6. Python tutorial <https://docs.keyestudio.com/projects/KS5009/en/latest/docs/Python/Python.html>__, and then to see the part of 6.2 get starter with Thonny .

How to get the code?

In folder …\Resource compression package\MicroPython Code , open file Initialization-of-window-servo-angle.py , or copy and paste the following test code into the Thonny IDE.

from machine import Pin, PWM
import time
pwm = PWM(Pin(5))
pwm.freq(50)

'''
The duty cycle corresponding to the angle
0°----2.5%----25
45°----5%----51.2

180°----12.5%----128
'''
angle_0 = 25
angle_90 = 77
angle_180 = 128
