Task-1: Speed control of motor I started doing it with Arduino nano, l293d and potentiometer to control the speed of motor. Circuit connections: Enable pins of l293d to pwm pins of Arduino and IN , pins to d 9 pin of Arduino. OUTput pins of l293d is connected to motor directly. Task-2:direction control of motor In this for circuit connection i used h-bridge of l293d to control direction of the motor .By varying the code for input pins , accordingly . Task-3: Point turn In this circuit , same l293d is connected to motor .Thus by keeping IN1 and IN2 Low and keeping IN3 High and IN 4 low .The motor will turn at one point around the axis. Task-4: Swing turn In this circuit ,l293d is connected to motor which in turn connected to chassis .Thus by keeping IN1-Low IN2-High IN3-High IN4-Low the motor will swing around the axis. Task-5: Line follower In this circuit ,i used l293d ,Ir sensor and motor .When Ir sensor is left on a black ground it will move forward and when car tries to come out of black ground and light reflects back to Ir sensor .Then we code such a way that car tends to go back to black ground .This way it follows the lane. Task-6: Obstacle Avoidance In this circuit ,I have used Ultrasonic sensor, motor and l293d along with Arduino Uno.When ultrasonic sensor detects am obstacle ..the car tends to avoid crash and move the other way. Task:7- Bluetooth controlled car In this circuit ,i had used Bluetooth module , l293d ,motor and chassis along with Arduino Uno and Android app. We have to pair Bluetooth module with mobile app and then we can control the car via bluetooth.
