Note on using the XBees
In rare cases, there may still be a protective film on the XBee slots. The film can be carefully removed with tweezers in order to use the slots.
I2C/Wire daisy chain
An I2C daisy chain enables the simple and efficient connection of several devices in a serial communication chain using the I2C protocol. The daisy chain configuration allows each device in the chain to send and receive data. This method is particularly useful in applications where space and resources are limited, as it minimises the number of physical connections required and at the same time enables robust and reliable data communication.
