digitalWrite(13, HIGH);This line turns on the LED connected to pin 13.HIGHsets the voltage of the pin to the logic HIGH level (usually 5V on most Arduino boards), which turns on the LED. delay(1000);This line adds a delay of 1000 milliseconds (1 second). It means the LED will rem...

You can now use ‘digitalWrite’ or other other functions to switch on an LED, relay, adjust PWM duty cycle (for example, increase the brightness of a lamp) whenever the button is pressed.A simple way to test this is to use an ‘if’ statement to check the value stored in ‘btstate...

I don’t have an example to show how to set up a network but basically you need to connect to each slave device one at a time. –Connect to module 1, get data, close connection. –Connect to module 2, get data, close connection. ...
The objects have type specific parameters too which can besetby `lv_<type>_set_<paramters_name>(obj, <value>)` functions. For example: ```c lv_slider_set_value(slider1,70, LV_ANIM_ON); ``` To see the full API visit the documentation of theobjecttypes or the related header file ...
打开file-example-mpu6050-mpu6050_DMP6,有现成的实例代码。由于我的esp32的板载LED灯的pin number是2,修改#define LED_PIN 13为2。中断pin 2修改为#define INTERRUPT_PIN 13 //修改后 #define INTERRUPT_PIN 13 // use pin 2 on Arduino Uno & most boards #define LED_PIN 2 // (Arduino is 13, ...
