Hello friends, I hope you are doing well. In today's tutorial, I am going to share our RFM69HCW Proteus Library . With this library, we can place two RFM69HCW RF modules in one Proteus design, connect each module to an Arduino Uno and send messages from a node to a gateway at 433 MHz. The gateway answers every message with an acknowledgement, and both boards print the signal strength on their Virtual Terminals. We will start with the basics of the module, install the library files and wire the circuit. After that, we will run the supplied two-Arduino simulation and study the control panel in detail, because its distance buttons let us test a link of up to 10 km. We will also understand both Arduino sketches and calculate the values shown on the terminals. The download includes the wired pr ...
