The Infrared Emitter is used to transmit infrared signals through an infrared LED, while there is an Infrared receiver to get the signals on the other side . An infrared LED is like any other LED, with its color centered around 940nm. We can use the emitter not only to transmit data or commands, but also to emulate remotes to control your home appliance using an Arduino. The Infrared Emitter can transmit signals reliable up to 10 meters. Beyond 10 meters, the receiver may not get the signals.
Now the The Infrared Emitter v1.2 is available, we optimized the circuit design to increase the transmission distance.
For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.

I was always curious about the firefly in my childhood. It is wonderful when it glows in the evening. I had my own “glowing firefly” after the chance to know about Techbox Tricks.
I caught the idea of “Light Pouring Cup” the evening I poured water from one cup into another. It would be cool if you can play with light in the dark.
Halloween is an autumn holiday that celebrate every year. In the “holy evening”, lovely children pick large orange pumpkins and carry bags from house to house saying “Trick or treat! Money or eat”.
Are you afraid of dogs? It can be true for most people. But sometimes you may approach a pet house with bad dogs inside by accident. What can we do to avoid things like this? Our cool play makers give us the answer!
Remote control is almost a standard accessory for most home applications, like TV, air conditioner and so on. Dozens of companies have released many different kinds of IR remote control products. Like airbox from haier.
In this tutorial I would like to introduce the Magic Bracelet.
Remote control is almost a standard accessory for most home applications, like TV, Hi-Fi, air conditioner and so on. Though remote control brings us leisure, when you really need it but have completely no clue where it is, or which one it is, you have eve
This is a remote control car. Not controlled by ubiquitous remotes, like joystick, but a set of NFC cards. That makes it a challenge to rational thinking. Want it run smoother and faster? That depends on how you design the commands set it executes.
