The IoT is going to be big, really big. If you thought that mobile was big you need to think again
If you are involved in creating devices or systems that might be classified as being the IoT you will know that your real problems stem from hardware issues such as communications, battery life and so on. After that you hit software problems - protocols, reading and dealing with the hardware at a low level. Only well after you have all of this sorted out does your mind turn to how to get the data crunched and some results displayed. A very common solution when this sort of problem is considered is to create a REST interface or an Android/iOS app.
Doorbells and other consumer electronics such as weather stations, run on the UHF (Ultra High Frequency) band at 433 MHz. The UHF band has a frequency ranging from 300 MHz to 3 GHz and transmitted mainly by line of sight; this means, radio waves are blocked by hills, large buildings etc. - in this case, we're just trying to ring the doorbell from a couple of meters away, using an Arduino.
This large 2.42" OLED I2C module can be used as a replacement for the smaller 0.96" display for which I originally designed the ProMini OLED clock shield. It is built around the same SSD1306 chip, and it only comes in yellow (for now).
The Raspberry Pi has an on-board audio jack, which is super handy for all kinds of sound effects and speech, just plug and go! However, for when you want better audio for music playback, a USB audio card can greatly improve the sound quality and volume, this tutorial will show you how...
Some projects that we build fulfill a genuine need for a new piece of hardware or software that will make life easier or fix a common problem. Other projects, on the other hand, we do just because it’s possible to do.
The story going around is Microsoft has destroyed FTDI USB to Serial Interface chips in the marketplace with the recent update. Many people are up in arms over this "clearly illegal act". But is it illegal, and how much harm has it done?
IBM has unveiled a service designed to drive the Internet of Things (IoT), enabling users to connect existing devices to the cloud and then build an application using IBM's Bluemix developer platform to collect data from the devices or send commands.
In the following 10-minute video, the Currah team is showing us all the details of Wood Lizzie, a project experimenting with Arduino Mega and Wi-Fi Shield, a very flexible steering system and the virtually unlimited control range afforded by WiFi...
