Here is the simplest sound making module. You can use high/low level to drive it. Changing the frequency it buzzes can produce different sound.
This LED light module has a shiny color, ideal for Arduino starters. It can be easily connected to IO/Sensor shield.
This module uses a ultra-bright infrared (IR) LED and a phototransistor to detect the pulse in your finger. The red LED then flashes in time with your pulse.
This LED module is of high brightness because the lamp beads it carries is 3w. We can apply this module to Arduino projects. For example, intelligent robots can use this module for illumination purpose.
