LAB 2 ESP32 Digital Inputs and Outputs  Objective : - To learn how to use GPIO port on the ESP32 controller to input and output digital value. - Able to use ESP32 to read input like switch and touch sensor and show output value. - Learn how to code using Arduino and print output. Equipment and components : •  ESP32 DOIT DEVKIT V1 Board •  3x 5mm LED •  10k Ohm resistor •  Pushbutton •  Breadboard •  Jumper wires •  Potentiometer Introduction :       ESP32 is a series of low-cost, low-power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. The ESP32 series employs either a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations, Xtensa LX7 dual-core microprocessor or a single-core RISC-V microprocessor and includes built-in antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power-management modules.       In this lab, I am going to learn how to use Arduino ESP32 to create a custom programm

      DKT 221/3 OPERATING SYSTEM PRINCIPLE     LAB MODULE 3     PART 1 1.     Use this command to open .bashrc file - sudo nano .bashrc 2.     Next we need to add the export PS1 command in the .bashrc. Go to the last line of coding and add - export PS1= "\h \u \w \$" 3.     In order to load the saved .bashrc file . We need to use this command then press ENTER - bash - . .bashrc 4.     To undo the change we need to go back to the .bashrc file again - sudo nano .bashrc 5.     Next . remove this command and save the changes - export PS1= "\h \u \w \$" 6.     After that , type the command again and press ENTER . Now we see that the PS1 is changed back to normal  - . .bashrc PART 2 1.     Create 3 dummy files , run and see the errors - ls -la F ile with no name.txt 2. Run the command again but enclose the filename in quotation . It wil work properly now - ls -la "File with no name.txt" 3.     Enter this command and press TAB . This will help

    DKT 221/3 OPERATING SYSTEM PRINCIPLE     LAB MODULE 1 QUESTION 1 Ramli is a Windows 7 user. However, He decided to use Mac Os X. For the first time use he need to know where to get hardware information in Mac OS X ? Please brief detail step by step to help him. (answer step by step with screenshots).   In order to use the Mac Os X,Ramli first need to about it first a the best place to find information about it is the wikipedia. .   There Ramli can find out if the Mac Os X is really better then Windows 7 and if his decision would help him in the long run.Below shows the difference between Windows and the Mac Os X Operating systems. This tells us that if Ramli wanted to use the Mac Os X he needs to either buy a new computer or use a VMWare. QUESTION 2 Sabrina love Espresso, a text editor Mac OS, but she don’t know how to install the software in Mac OS. (answer step by step with screenshots).   In order to install the Espresso,Sabrina need to go
