5 Arduino Project Problem Statements for Beginners

If you are starting off with Arduino, then the following 5 projects can be taken up by you −

7-segment display using Arduino

• Interface a 7-segment display with Arduino and count from 0 to 9 on that display. This will help you get a good understanding of GPIOs

• As a next step, you can interface Arduino with a potentiometer, and display the truncated voltage value (read using ADC) on the 7 segment display.

Fire Alarm System

• Interface the Arduino with a smoke detector or a flame sensor and a buzzer to give a warning as soon as the readings from the smoke detector cross a threshold

• You can read more here.

Water Level Indicator

• Interface the Arduino with ultrasonic sensor and a buzzer to give an indication of the water level in a container.

• You can improvise and connect Arduino to an OLED screen to give live updates of the water level.

• You can read more here.

RFID scanner with Arduino

• Interface your Arduino with a RFID reader and light an LED if the RFID card is read properly.

• You can improvise this further, and control a relay switch based on the correct value of the RFID, to control an appliance

• You can read more here.

Line Follower Bot −

• Program the Arduino to control a bot’s movement to follow a white line.

• You will need to interface Arduino with IR sensors and motor drivers and also study a bit about controls (PID knowledge will help)

• You can read more here.
