ESP32 Starter Kit
5. Test Result
After connecting the wiring and uploading code, open serial monitor to set baud rate to 9600, the analog value will be
displayed, withing the range of 0-4095.
6. Knowledge Expansion
We will use this photoresistor to sense the ambient light intensity. The two columns of middle are included in this
experiment to represent light intensity. The stronger it is, the more lighted LEDs will be. This forms a “light pillar”.
