In this Arduino tutorial we will learn how to use the HC-12 wireless serial communication module which is capable of making a long range wireless communication between multiple Arduino boards, with distances up to 1.8km. For this tutorial I made two basic examples explaining the how to connect the HC-12 module and...

2016年11月2日 · Learn about the HC-12 transceiver module and how to use it to transmit and receive digital data. The HC-12 is a half-duplex wireless serial communication module with 100 channels in the 433.4-473.0 MHz range that is capable of transmitting up to 1 km.

2016年12月2日 · HC-12 wireless RF UART communication module is a new generation of multi channel embedded wireless data transmission module. Radio frequency of 433.4 - 473.0MHz, can be setting communication channel, step is 400kHz, a total of 100 channel.

In this instructable you have learned how to use the HC-12 for long distance communications between Arduinos. You have learned how to make an instant messenger, a toggle button, a momentary button, how to use some string operators and functions, how to change the HC-12 settings and how to use a different antenna.
