you don’t even need an external amplifier

The projects are suitable for beginners aged 9 and over (including teens and adults)

As it requires hand-tuned assembly it is only for AVR cores but others may have ported this chip driver code so please google around

Or we can make a remote-control unit

You can even talk via wireless communication between two micro:bits with this kit to be able to monitor the weather without being exposed to it
