第一个Arduino开发板的代码：/* Arduino Long Range Wireless Communication using HC-12 Example 02 ...
For this tutorial I made two basic examples explaining the how to connect the HC-12 module and make a basic communication between two Arduinos and an additional example where using an accelerometer sensor at the first Arduino I wirelessly control the position of the stepper at the second Ard...
so compared to the previous example, I had the move the Enable A and Enable B pins of the L298N driver to the pins number 2 and 3 of the Arduino board.You can get the NRF24L01 module on the followingAmazon link.
/Firmware - Arduino example code. Make sure to check the pin definitions and what you are connecting to. Documentation Hookup Guide - Basic hookup and project example using the ultrasonic sensor. (Note: The example code used in this tutorial is slightly different than the basic example used ...
Try different pins, for example use Pin 2 and 3 and reseat all the connections. Reply Mohammad Hasan try to remove the arduino IDE and reinstall it again, then go the same steps you made . Reply Mohammad Hasan try to remove the arduino IDE and reinstall it again. ...
This guide shows how to use the HC-SR04 Ultrasonic Sensor with the ESP32 board using the Arduino core. The ultrasonic sensor uses sonar to determine the distance to an object. We’ll show you how to wire the sensor to the ESP32 and provide several example sketches to determine the ...
So, here we provide an example of how to use the HC-SR04 ultrasonic sensor with the Arduino. In this project, the ultrasonic sensor reads and writes the distance to an object in the serial monitor. The goal of this project is to help you understand how this sensor works. Then, you ...
For the AtMega168 be sure to reduce the serial buffer size by setting RX_BUFFER_SIZE to 32 or less in hardware/arduino/cores/arduino/HardwareSerial.cpp. I use 16.SD CARD INIT PROBLEMSSome SD card are very sensitive to the SPI bus speed for initialization. Try setting SPI_INIT_SLOW non...
