Exercises

Exercise 1

• Read the light sensor continuously, once a second, and display/print it. 
  • make a sprite say/display it using the Live mode of mBlocks or
  • print it on the serial console of Arduino IDE.
  • Try both code and mBlocks!
• Whenever the light exceeds a certain threshold (you can set an appropriate threshold after reading the values), the buzzer should beep.
• You will have to take off the mBot cover for the light sensor to work well.

Exercise 2

• Read the line follower sensor and change the colour of RGB LEDs accordingly.
  • 4 different colors for the 4 different scenarios encountered by the line follower sensor.

Exercise 3

• Read the ultrasonic sensors and control the motor accordingly

  • The threshold can be any reasonable value for now. We can tune this later.

    
    

    Left Ultrasonic Sensor	Right Ultrasonic Sensor	Action	Left Motor	Right Motor
    < threshold	< threshold	Go forward	turn forward	turn forward
    < threshold	> threshold	Turn right	turn forward	stop
    > threshold	< threshold	Turn left	stop	turn forward
    > threshold	> threshold	Go back (you are lost!)	turn backward	turn backward

    * The above is a general idea. You should make refinements to the logic as well as thresholds for the actual competition
