Using IFTTT with the Raspberry Pi

Using IFTTT with the Raspberry Pi

IFTTT (If This Then That) is a free IoT service that allows you to send a trigger from one device/thing, and allow that trigger to make something happen elsewhere. Confusing? Perhaps, but a quick example should help show the simplicity of it: Our recipe ('applet') could be: "If I send an email with the subject 'turn on', then switch on my smart lightbulb". The 'THIS' is the email and the 'THAT' is lighting the WiFi lightbulb. Simple right? IFTTT Services The exciting thing about IFTTT is the sheer number of services you can use as either triggers (THIS) or actions (THAT). There...

Auto-Starting Programs on the Raspberry Pi

The Raspberry Pi 3 Model A+ is here!

It's been a little over half a year since the launch of the last Raspberry Pi, the 3 Model B+, but it's been a good 3 years since the original 1 Model A+ was launched and a lot has changed in the Raspberry Pi World. So what's new? The new Model A+ has seen a big upgrade from the last A+ to give it the same processor as the Raspberry Pi 3 B+, which is a 64-Bit 1.4GHz Quad core ARM Cortex 53 processor using the Broadcom BCM2837B0 chipset along with the same onboard wireless LAN and Bluetooth capabilities as...
