As mentioned in the previous posts, if you plan on using the Arduino boards from remote locations, the only way to connect them to the internet is by using GSM shields. The most commonly used GSM shield (or module) is of course the SIM900. Their price is way lower than any other and you can […]

Arduino: Save data to database
While broadcasting data over a dedicated web page on your home network is useful for a home project, fundamentals of an advanced project are to be able to store data you read from your connected sensors. This way you can monitor live data, but are also able to get historic information. It also allows you […]
Arduino: Display data over local network
Arduino can gather and display all sorts of data from its sensors (or what ever you connect to it), but the real power from the data comes when you can monitor it over network. There are 2 ways you can connect Arduino to your home network: over Wi-Fi, or through a network (UTP) cable. […]
Arduino: Light sensor (basics)
In this article I will show you how to measure the amount of light in a room with Arduino and a light sensor. Measuring light is done by a sensor with a photoresistor (photocell). Photoresistor is basically a resistor which resistance depends on the amount of light it absorbs. Lesser the light higher the resistance […]
