How to use the FLEX module for remote control
The FLEX radio module can be used as a wireless sensor node transmitting sensor values (like temperature, humidity and alarm triggers) but it can also be used as a remote control device to for wireless automation. For example you may want to switch a light on/off based on some other event, like a door opening or motion being sensed. The FLEX module has 5 IO pins that can be connected to external circuits and independently controlled. In the video below you can see the FLEX module turning LED lights on/off based on wireless messages from a controller (e.g. Raspberry Pi and wireless base station).
