the “mp3 player”(Mic & Speaker Block) needs to be connected to the Wifi block. The laser block shoots laser after you press the switch in the module - it has a little battery inside. It can be recharged with Wifi Block or other micro-usb charger. The laser block is better used with a light-sensor: it creates a security device.
