In thisArduino I2C tutorialwe will useI2C communication between two arduino boardsand send (0 to 127) values to each other by using potentiometer. Values will be displayed on the16x2 LCDconnected to each of the Arduino. Here one Arduino will act as Master and another one will act as Slav...
Although it is often enough to use a single Arduino to read from a sensor and display the result in the serial window or on an LCD screen, sometimes this is just not enough, and you may want to split the task between 2Arduinos. An example of this might be an Arduino sensing the rot...
Project: RS485 Serial Communication between two Arduino boards (Control LED Brightness) Let us demonstrate an example of RS485 serial data transfer between two Arduino boards using the MAX485 TTL to RS-485 module. Our aim will be to send ADC values from the master Arduino connected with a pot...
Connecting Two Arduino Board Using I2C As Master and Slave To establish I2C communication between two Arduino boards, theSDAandSCLpins of both boards must be connected and share a common ground. The communication can be achieved by using the inbuilt Wire library in Arduino which contains functions...
Parallel connection between the Arduino and peripherals via input/output ports is the ideal solution for shorter distances up to several meters. However, in other cases when it is necessary to establish communication between two devices for longer distances it is not possible to use parallel ...
Arduino and HC-12 Example 01 – Arduino Code AT Commands: Example 02 HC-12 Wireless Communication: Stepper Motor Control using an Accelerometer Overview For this tutorial I made two basic examples explaining the how to connect the HC-12 module and make a basic communication between two Arduin...
Figure 1. Communication between two Arduino using UART How Do Uarts Work? At a high level, a UART works by converting parallel data (bits transmitted in parallel, or all at once) into serial data (bits transmitted one at a time) and vice versa. The process begins when the transmitting d...
I am “just” trying to transfer data backwards and forwards between the client and server which are both ESP8266 Arduino clones and establishing my own Access Point. So, I have deleted the display and temperature etc interfaces. 1. I cannot get the server.on step to work as it says it...
