Design your project as follows: put the LEDs, the piezo and the sensor on the breadboard, connect the LEDs to different pins, piezo and the temperature sensor to the required pin. When the sketch starts, it should display a message in the Serial Monitor asking you to enter a value: YourName (for example, Fadi), or YourID (for example, 21930213) or YourFamilyName (for example, Waked). The program should display the entered value, the Celsius temperature and which LED is ON in the serial monitor. If you enter YourName, press Enter, the Yellow LED should be turned on and all the required values should appear in the serial monitor, If you enter YourID, press Enter, the Green LED should be turned on and all the required values should appear in the serial monitor, if you enter YourFamilyName, press Enter, the Blue LED should be turned on and all the required values should appear in the serial monitor (see the sample run), otherwise the piezo should play a tone and this message will appear in the serial monitor: “You should enter yourName, ID or familyName”.

You have a linux system that has a 1000gb hard disk drive, which has a 90gb partition containing an ext4 filesystem mounted to the / directory and a 4gb swap partition. currently, this linux system is only used by a few users for storing small files; however, the department manager wants to upgrade this system and use it to run a database application that will be used by 100 users. the database application and the associated data will take up over 200gb of hard disk space. in addition, these 100 users will store their personal files on the hard disk of the system. each user must have a maximum of 5gb of storage space. the department manager has made it very clear that this system must not exhibit any downtime as a result of hard disk errors. how much hard disk space will you require, and what partitions would you need to ensure that the system will perform as needed? where would these partitions be mounted? what quotas would you implement? what commands would you need to run and what entries to /etc/fstab would you need to create? justify your answers.
