Raspberry Pi uses a variety of input/output devices based on differnt protocols like HDMI, USB, and Ethernet to communicate with outside world. In this course you will learn how to use these protocols with other external devices (sensors, motors, GPS, screens etc.) to get an IoT device to interact with the real world. Most physical devices use analog signals whereas computer hardware is digital so in this session you will learn how the signals are converted to and fro and how to considered these as while programming your device. You will learn how to build more sophisticated hardware systems using Raspberry Pi expansion boards to create fun and exciting IoT devices.

The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. It is a capable little device that enables people of all ages to explore computing, and to learn how to program in languages like Scratch and Python. It’s capable of doing everything you’d expect a desktop computer to do, from browsing the internet and playing high-definition video, to making spreadsheets, word-processing, and playing games.
The Arduino and Raspberry Pi are both useful for robotics projects but have some important differences.
● Arduino. An Arduino is a microcontroller, which is like a simple computer but which runs and loops a single program that you have written on a PC. This program is compiled and downloaded to the microcontroller as machine code. The Arduino is well suited to low-level robot control and has features like analogue-to-digital conversion for connecting analogue sensors.
● Raspberry Pi. A Raspberry Pi (RPi) is just like a normal PC and so is more versatile than an Arduino but lacks features like analogue-to-digital conversion. The RPi runs a Linux operating system (usually Raspian). You can connect a keyboard, mouse and monitor to a RPi, along with peripherals like a camera - very useful for robotics. (Due to the fact that the RPi runs Linux you can also install ROS although it can be a bit tricky to set up.)
It is recommended that you use a power supply that is >=1A. It is know that things may not function properly without proper power especially if you are using a keyboard or other non externally powered devices (ie. HDDs, flash drives)
