COMMON TASK REPORT-2

TASK-6\n# LED TOGGLE\n\nthe task is to make standalone web server with an ESP32 to controls the LED connected with ESP32 GPIOs\n\n## MATERIALS REQUIRED :\n1. BREAD BOARD\n2. TWO LED LIGHTS\n3. TWO RESISTORS\n4. JUMPER WIRES \n5. ESP32 MICROCONTROLER\n\n## ESP32 MICROCONTROLLER :\nESP32 is a low-cost, low-power Microcontroller with an integrated Wi-Fi and Bluetooth. It is the successor to the ESP8266 which is also a low-cost Wi-Fi microchip albeit with limited vastly limited functionality.\n\nESP32 are commonly found in\n * Smart industrial devices. \n * including Programmable Logic Controllers (PLCs). \n * Smart medical devices.\n * wearable health monitors.\n * Smart energy devices.\n * HVAC and thermostats.\n\n \n\n## CIRCUIT WORKING:\nonce the circuit is connected properly ,upload the the codes to microcontroller ,once the code is uploaded we should give the particular WIFI SSID and Password will be receiving an IP address when the WIFI gets connected .\n\n## CODES TO BE UPLOADED IN THE MICROCONTROLLE :\ncopy the IP address and paste it in chrome ,we will be receiving an web page with the option of ON and OFFR* :\n c\n // Load Wi-Fi library\n#include \n\n// Replace with your network credentials\nconst char* ssid = \vvvvvvxxxxxx\";\nconst char* password = vvvvvvxxxxxx\";\n\n// Set web server port number to 80\nWiFiServer server(80);\n\n// Variable to store the HTTP request\nString header;\n\n// Auxiliar variables to store the current output state\nString output26State = \"off\";\nString output27State = \"off\";\n\n// Assign output variables to GPIO pins\nconst int output26 = 26;\nconst int output27 = 27;\n\n// Current time\nunsigned long currentTime = millis();\n// Previous time\nunsigned long previousTime = 0;

BREAD BOARD \n2. LDR ()\n3. RESISTORS\n4. AND GATE (74HC08)\n5. LED LIGHT\n6. BUZZER\n\n## CIRCUIT :\n\n\n\n\n\n\n\n\n\n\n### TASK-8\n# UBUNTU \n## \nThe objective of the task is that\n\n- to create a folder named test\n- CD into that folder\n- create a blank file without using any text editor\n- list the files in the particular folder\n- create 2600 folders in this folder each folder is named like A$1\n- concatenate two two text files in the folder containing random text and display them on the terminal.\n\n## To create a folder :\n- the command pwd is used he pwd command writes to standard output the full path name of your current directory (from the root directory)\n- *touch fileName – Create an empty file. cat > filename – To create a new text file under Ubuntu, use the cat command followed by the redirection symbol ( > ) and the name of the file you want to create. Press Enter, then type the text and once you are done, presUse \n- the mkdir command to create one or more directories specified by the Directory parameter.s the CRTL+D to save the file.\n\n\n## TO CREATE 2600 FOLDERS IN UBUNTU :\n- Use mkdir command\n- mkdir folder name\n- cd folder name\n- touch test_folder name\n- for i in {1..2600}\n- mkdir folder name $i\n- done\n## CONCATINATION OF TWO FILES :\n- touch text1.txt text2.txt\n- nano text1.text\n- A terminall will be open where we can type our txt\n\nexample- HELLO MY SELF ANJAL K NAIR \n- nano text2.txt\n- type second sentence\n\nexample-IAM MARVEL BATCH STUDENT \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n"
