  1. The commands are sent from TX of arduino A to RX of arduino B through serial commuication.
  2. With the help of an audio amplifier, we can get an input between 1.5 and 3.5 volt which is convenient to utilize in Arduino.

  1. At the beginning we intended to use a temperature sensor to detect the state of the candle. However we found that the characteristic of temperature sensor did not meet our requirement for instantaneousness. Since the candle also produces light, LDR was the best choice.
  2. Testing the system in various lighting environments is very important. With the analysis of our test results we could set an appropriate range for the LDR input in Arduino code.

  1. The accelerometer was fairly sensitive, which gave us a lot of data that we didn’t need. By a mathematical process we managed to get smoothed and simplified data with which we could control the servo motor comfortably.
  2. Since USB only offers 100ma for one unit, using an accelerometer and servo simultaneously may give wrong results. A 9 volt battery for Arduino or offering the servo some external power supply could be a solution.
