A. Using Arduino and sensors/actuators
i. Interfacing Light Emitting Diode(LED)- Blinking LED :
This use case will be used for familiarizing the GPIO peripheral of atmega micro
controller. The LED will be used as a device and GPIO will work as output mode.
ii. Interfacing Button and LED – LED blinking/glow when button is pressed
This use case will help to understand the GPIO in two different modes, Input –
Button and LED – output mode.
iii. Interfacing Light Dependent Resistor (LDR) and LED, displaying automatic
night lamp

This use case will help to understand ADC peripheral and how to read analog
data from sensors.
iv. Interfacing Temperature Sensor(LM35) and/or humidity sensor (e.g. DHT11)
This use case will help to connect traditional environmental monitoring sensors
(Temperature and humidity) to the Arduino development board. Also use the
suitable libraries for implementing these case studies.
v. Interfacing Liquid Crystal Display(LCD) – display data generated by sensor on
This case study will demonstrate how to provide local display unit with Arduino
micro controller. Use suitable libraries for implementing these case studies.
vi. Interfacing Air Quality Sensor-pollution (e.g. MQ135) – display data on LCD,
switch on LED when data sensed is higher than specified value.
This use case will help to understand how to use traditional smart pollution
management sensors with Arduino platform for developing applications as a part
of smart city projects.
vii. Interfacing Bluetooth module (e.g. HC05)- receiving data from mobile phone on
Arduino and display on LCD
This use case will help to understand the connectivity solution to Arduino to a
gadget like mobile phone. Bluetooth is used as connectivity solution in this
viii. Interfacing Relay module to demonstrate Bluetooth based home automation
application. (using Bluetooth and relay).
This use case will enable the IoT node capability of Arduino development boards
by integrating actuator (relay connected to GPIO) to Arduino board and remote
connectivity (Using Bluetooth) using a mobile phone with the help of a readily
available Bluetooth serial application
