WEEK-4 CHALLENGE

QUESTION:

1. Implement control logic of a “washing machine” using Stateflow as per given sequence:

• If the power supply is available, the system gets activated
• If the Water supply is not available, stop the process & indicate through LED
• Soaking time should be 200s followed by Washing time of 100s.
• Then rinsing happens for next 20s & dryer runs for 50s

After all the processes have completed turn on the finished LED

2. Make a Simulink chart for the “Gear shift” logic as per below conditions:

Speed Range(kmph) Gear

0 to 15 1

16 to 25 2

26 to 40 3

41 to 60 4

Above 61 5

Give speed input while the simulation is running & display the gear number.

GEAR1 IS ENGAGED WHEN SPEED IS BETWEEN 0 TO 15 KMPH

GEAR2 IS ENGAGED WHEN SPEED IS BETWEEN 16 TO 25 KMPH

GEAR3 IS ENGAGED WHEN SPEED IS BETWEEN 26 TO 40 KMPH

GEAR4 IS ENGAGED WHEN SPEED IS BETWEEN 41 TO 60 KMPH

GEAR5 IS ENGAGED WHEN SPEED IS ABOVE 61 KMPH
