Note: The 10KΩ resistor is matched to the photoresistor and the ambient light. The value of 10KΩ is suitable for a wide range of photoresistors and indoor lighting conditions. If your coffeebot doesn’t seem responsive outdoors or in a bright room, replace the 10KΩ resistors with 1KΩ resistors. You may have to experiment with different values to suit your conditions.
