Measure the brightness of a light source and display the light intensity on a seven segment display

In this light intensity indicator, we will use a 7-segment LED display to display the intensity of the light received by a photo resistor. The photo resistor will be connected to an analog input on a microcontroller, and the microcontroller will read the analog value and convert it to a digital value. This digital value will be mapped to a range of 1 to 9, with 1 corresponding to low light intensity and 9 corresponding to high light intensity. The microcontroller will then drive the 7-segment LED display to display the mapped value, providing a visual representation of the light intensity. Alternatively, the user could toggle between different display modes, such as displaying the raw analog value or both the raw value and the mapped value..
