Task 1 : Speed Control of DC Motor

In this task, I learnt how to control two DC motors simultaneously using a single motor driver(dual H-Bridge L293D). We can change the speed of the motors using a potentiometer.

Task 2 : Direction Control of DC Motor

In this task, I learnt how to control the direction of DC motors using a dual H-Bridge L293D motor driver along with an arduino uno.

Task 3 : Point turn of a Vehicle

In this task, I designed a vehicle using two DC motors. I applied all the concepts that I learnt from the previous two tasks. This vehicle achieves point turn by running one of the DC motor in clockwise direction while the other in anti-clockwise direction.

Task 4 : Ultrasonic Sensor

In this task, I mounted an ultrasonic sensor on the vehicle I had built in the previous task. I coded the vehicle in such a way that it takes a point turn when the ultrasonic sensor detects an object less that 20cm in front of the vehicle.

Task 5 : Temperature Detection

In this task, I measured temperature using an lm35 temperature sensor and Arduino and displayed it on the serial monitor.

Task 6 : Temperature and Humidity Detection

In this task, I measured temperature and humidity using a DHT-11 sensor and Arduino and displayed the readings on the serial monitor.

Task 7 : Battery Charging

In this task, I charged a Li-on battery using solar panel and a TP4056 Li-Ion Battery Charger Module.

Task 8 : Solar Panel

In this task, I made a very basic solar panel using silicon diodes. This task demonstrates the principle behind solar charging.
