In 2013, ThingSpeak was used in 158 countries and territories. The vast majority of the traffic came from countries in North America, Europe, Australia, and South America. ThingSpeak is growing quickly around the world!

Introducing… TalkBack!
We have developed a new ThingSpeak App and it is available now to all ThingSpeak Users.
The new TalkBack App allows devices to check ThingSpeak for commands to execute. TalkBack is perfect for battery-powered devices that need to sleep most of the time and wake up to see if there is anything to do and then go back to sleep, like a door lock for example. The lock is mostly going to be asleep to save battery power, but it can wake up periodically and check TalkBack or be woken up by a button press to see if it should be opened or not.
Devices powered by ThingSpeak and now with TalkBack will be able to both push sensor data to the ThingSpeak Cloud and check TalkBack if any commands are available all in one request. To get started, we have the complete TalkBack API Documentation and an Arduino Yún Tutorial available now.
With the release of TalkBack, we created a tutorial for the Arduino Yún. The “Yún” is a special combination of easy-to-program Arduino with an additional processor, an Atheros AR9331, running Linux and the OpenWrt wireless stack. Programming the Arduino via USB is identical to the Arduino Leonardo. Once the Arduino Yún is connected to Wi-Fi, the Arduino has full access to ThingSpeak Cloud Services and the TalkBack App and API. Check out the Controlling the Arduino Yún with TalkBack tutorial for a step-by-step way of controlling the Arduino Yún via TalkBack and the ThingSpeak Cloud.
TalkBack is available now to all ThingSpeak Users and to new users by Sign Up for Free at ThingSpeak.com! Please feel free to share with us and the ThingSpeak Community with the awesome ways you use TalkBack with your ThingSpeak Projects!
[Andrew Bythell] created a ThingSpeak Java Client for the complete ThingSpeak API. This Java Client makes it really easy for Java (or Processing) developers to add cloud connectivity to applications and non-networked devices. “The purpose of the ThingSpeak Java client is to enable non-networked Device-to-ThingSpeak gateways and other applications for performing advanced analysis of data feeds,” said Andrew.
So, by using Java, a simple “Hello World” app becomes this easy…
Channel channel = new Channel(channelNumber, apiWriteKey);
Entry entry = new Entry(); entry.setField(1, "Hello World"); channel.update(entry);
All of the source code and documentation are available on GitHub. Get started right away with building your Internet of Things with the Java Programming Language and the ThingSpeak Cloud.
Excellent work Andrew – thanks for contributing to the Open Source ThingSpeak Community!
