Raspberry Pi- An Educational Tool Raspberry Pi is a single-board credit-card-sized computer. It was developed by Raspberry Pi Foundation in UK. The objective behind its development was the introduction of basic computer science in schools. It is so simple to program as well as cheap to tamper during experiments. The idea of Raspberry Pi was proposed in 2006 by Eben Upton and a group of teachers, academics and computer enthusiasts at Cambridge University. The initial slot was manufactured in Chine and Tiwan. It was released on 29 th February 2012. About half million units were sold within six months of its release. Raspberry Pi has two models named as Model B and Model A. Model B came initially and then Model A came in the starting of the year 2013. The device has 5 volt USB. A 1200 mA power supply is more than sufficient to run it. 1 Amp is the maximum power that Raspberry can use. An external powered USB hub is required to connect USB device above 1 Amp. Basically, Model

Supervisory control and data acquisition (SCADA) is an industrial control system which is used in many modern industries like energy, manufacturing, power, water transportation, etc. SCADA systems organize multiple technologies that allows to process, gather and monitor data SCADA systems range from simple to large configurations. Most of the SCADA applications use human machine interface (HMI) software that permits users to interact with machines to control the devices. HMI is connected to the motors, valves and many more devices. SCADA software receives the information from programmable logic controllers (PLCs) or remote terminal units (RTUs), which in turn receive their information from the sensors or inputted values which we have given manually. SCADA in a power system is used to collect, analyze and monitor the data effectively, which will reduce the waste potentially and improve the efficiency of the entire system by saving money and time. What is SCADA?
