From last Week’s flow chart, En Cui and I worked on creating a mock up circuit which follows a segment of the flow chart.

Mock Up model 1

We started with a basic microphone set up.

From here we tested to see if we can get the input reading through the serial monitor of the surrounding sounds, and the changes when we spoke into the microphone.

Problems:

• Serial Montitor showed that the input was either a ‘high’ at 1022/1023, or a ‘low’ 0.

Conclusion at this segment:

• We thought our microphone was iffy

Nonetheless we continued, as the microphone was still able to detect sound we decided it will be good enough for now and we will solve this issue later.

Mock Up model 2

Subsequently, we added onto the first model to include the LED output.

From here the code was expanded to include a code to control an RBG LED and to read frequency and Volume of the surrounding environment. Initially, the code was done in  random way where for every 3 digits that the frequency had the digit in the hundred place would be the percentage of red, tens the percentage of blue, and ones for green, that would make up the colour that the light bulb would create.

Problems:

• The colour of the lightblub was coming out abit too randomly

So from there we attempted to group a range of frequencies and match them to a colour. Subsequently we made it such that the volume is matched to the brightness of the LED.
