DIY LiFi Communication Device

Hello Friends! So after working and researching on Li-Fi based applications over the past 2 years, we finally decided to make a DIY tutorial as a lot of people were emailing us for the same. As you all must have heard about Li-Fi, it stands for Light-Fidelity. Li-Fi technology, proposed by the German physicist—Harald Haas, […]

DIY DTMF Home Appliance Controller

    We use many different types of communication in control applications to control home appliances, industrial appliances, and other types of automation. There are two types of communication that is we generally use – one is wired and other one is wireless. In wireless communication we transmits signal wirelessly, like using radio frequency (RF) […]

DIY Programming Arduino Lilypad using Arduino Uno

    Hello Guys, In this blog we will tell you how to program an Arduino Lilypad using an Arduino Uno. As you know Lilypad is becoming quite a useful board for wearable applications, it needs an external programmer to change its firmware or code. Here we use Arduino Uno as a programmer and demonstrate […]
