What is a microcontroller?? A microcontroller (or MCU, short for microcontroller unit) is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals.

TEAM ARDUINO

ARDUINO IS SO POPULAR BECAUSE.. OPEN SOURCE platform Allows easy and fast prototyping Large assortment of predefined libraries Huge community of people working on the same environment

ARDUINO UNO

SPECIFICATIONS…. Advanced RISC architecture Programmable serial USART, master/slave SPI interface Operating voltage: 5V 20 digital I/O pins,6 of which support PWM 6 analog input pins supporting 10-bit ADC Clock speed: 16 MHz

ATmega328

THE CRYSTAL OSCILLATOR

TYPES OF ARDUINO BOARDS

The difference lies mainly in the memory and number of pins…

THE ARDUINO LEONARDO

ARDUINO IDE The Arduino Integrated Development Environment - or Arduino Software (IDE) - contains a text editor for writing code, a message area, a text console, a toolbar with buttons for common functions and a series of menus. It connects to the Arduino and Genuino hardware to upload programs and communicate with them.One of the major features which gives Arduino an edge over other MCUs is the availability of the Serial Monitor.

INNOVATION BEING THE KEY…

RF: Encoding & Decoding When electric current oscillates at radio frequencies, energy is radiated off the current carrying conductor in the form of electromagnetic waves (radio waves).This forms the basis of Radio Transmission. We use RF communication to transfer information between two or more points that are not physically connected. We will fundamentally use it to control any device (e.g. motors, LEDs etc) through a remote control which is independent of any physical connections with the device.

Types of rf module Transmitter Modules: A transmitter module is a small device used in transmitting radio waves and also modulating the wave to carry data. These devices are usually implemented alongside a micro controller, which provides data to the module to be transmitted. Receiver Modules: RF Receiver Modules is used for receiving the modulated RF signal and demodulating it. There are two types of receiver module, namely superheterodyne receivers designed using a series of amplifiers to extract data from a carrier wave and super-regenerative receivers in which operation varies according to change in temperature and power supply voltage.

Types of rf modules Transceiver Modules: These devices are a mix of both transmitter and receiver. Such devices are designed in either Half-duplex operation or Full duplex modules which are expensive due to its added complexity. Example: NRF module(2.4 GH) System on a chip (SoC) Module: it is very similar to a transceiver module, but is created with an on-board micro controller. This controller handles radio data packetisation or managing a protocol.
