A darlington transistor can be used as a solid state switch controlled by a low current PICAXE output and able to switch a higher current load that a PICAXE output could not handle directly.
Activate a transistor
The following program will activate a transistor connected to output B.1 for a second every five seconds.
The BCX38C darlington transistor create module can control many diffrent devices, such as the buzzer shown here.
