This 5mm Water-clear Phototransistor will pick up visible and infrared light and conduct current. When light reaches this high sensitive/fast response time component it's much like current reaching the base of a transistor which allows current to flow from collector to emitter.
FreeM is a wireless Infrared I2C controller for completely stand-alone programming and control of BlinkM smart LEDs. It's like an invisible wire linking a Remote, a LinkM, and/or an Arduino to BlinkMs.
Unsure of how to interface RGB strips to your own microcontroller? Why not go with this ready-to-go remote controlled LED controller! Comes with a small remote that allows you to use wireless infrared signals to change the RGB strip color and lighting effects.
The surface mount version of our smallest, but prominent, PICAXE microcontroller. Very popular in education due to its low cost and small size, but also popular in a wide range of hobbyist projects. Small but perfectly formed!
