List of Experiments:

• 1. Connect an LED to GPIO pin 25 and control it through command line.
• 2. Connect an LED to GPIO pin 24 and a Switch to GPIO 25 and control the LED with the switch.
• 3. The state of LED should toggle with every press of the switch Use DHT11 temperature sensor and print the temperature and humidity of the room with an interval of 15 seconds
• 4. Use joystick and display the direction on the screen
• 5. Use Light Dependent Resistor (LDR) and control an LED that should switch-on/off depending on the light.
• 6. Create a traffic light signal with three colored lights (Red, Orange and Green) with a duty cycle of 5-2-10 seconds.
• 7. Switch on and switch of a DC motor based on the position of a switch.
• 8. Convert an analog voltage to digital value and show it on the screen.
• 9. Create a door lock application using a reed switch and magnet and give a beep when the door is opened.
• 10. Control a 230V device (Bulb) with Raspberry Pi using a relay.
• 11. Control a 230V device using a threshold temperature, using temperature sensor.
• 12. Create an application that has three LEDs (Red, Green and white). The LEDs should follow the cycle (All Off, Red On, Green On, White On) for each clap (use sound sensor).
• 13. Create a web application for the above applications wherever possible with suitable modifications to get input and to send output.
