Building on his previous experiments in sending data between two Arduino boards using light beams, Costa Yannakis has now demonstrated this method using a laser pointer and with some other modifications has managed a faster data rate. This was made possible by creating his own data protocol for accuracy and also expanding the area of sensitivity for the light sensor.
Costa's system sends data which can be printed using a small thermal printer with the receiving Arduino, and by using a laser instead of an LED the distance can be increased considerably. A quick demonstration is shown in the following video:
Kudos to Costa for using his imagination and sharing the project with us, of which you can find all the details on his website. And we're on twitter and Google+, so follow us for news and product updates as well.
Looking to detect changes in light levels? Don't fool about with irregular light-dependent resistors. Instead use our LIGHT: light sensor module with the TEMT6000 light sensor which gives consistent and repeatable readings even between different units. Simple to use and versatile for many applications. For more information and to order,click here.
