Build a Secret Radio Chat Device<\/h1>\n

An article in Raspberry Pi magazine MagPi by PJ Evans of Milton Keynes shows how you can build a 433 MHz radio chat device to send wireless messages without needing WiFi<\/p>\n

“Sure, WiFi is all well and good, but is it the only option for wireless communication on the Raspberry Pi? What if there isn\u2019t a network available or you need a longer range? 433 MHz radio is where you want to be. In this tutorial we\u2019ll add this capability to a pair of Pi boards and show how to send wireless messages from one to the other with no WiFi network. Then, we\u2019ll increase the range with a touch of science and start talking to RF-based switchable main sockets. Have Pi-controlled sockets all around the house!”<\/p>\n

The tutorial article appears on pages 44-47 of issue 75 November 2018 MagPi and can be seen online at
