Kira’s Final Project Planning

Material Preparation:
Photoresistor: used to detect the ambient light intensity.
Color LED: used to display different colors.
Microcontroller (e.g. Arduino): used to control the LED and read the value of the photoresistor.
Resistor: used to limit the current and protect the LED and the photoresistor.
Breadboard and/or soldering tool: used to build the circuit.
Wires: to connect the parts of the circuit.
Power source: can be a battery or a stand.
Sensors (optional): such as temperature and humidity sensors for weather-related functions.
Programming cable: connects the microcontroller to the computer.

Circuit diagram design:
Connect the photoresistor to one of the analog inputs of the Arduino.
Connect each of the RGB LED color pins (red, green, blue) to a digital output of the Arduino through appropriate resistors.
If needed, connect the sensor other to the Arduino.
Connect the power supply:
Ensure that the microcontroller has a stable power supply.
Choose a battery or adapter as needed.
Consider additional features:
To control the color according to time or weather changes, an Ethernet module (e.g. ESP8266) may be needed to get the time or data.
Write and upload code:
Write code to read the value of the photoresistor and control the brightness of the LED or switch it on/off based on that value.
Write code to change the LED color, either based on time or weather data obtained from the network.
