< Process – Speaker Test & Output Synthesizer >

The main aim of this round of progress is to really get the speaker to work and get an output out.

Solving Speaker Problem
So, I was referring to the Adafruit website and study the Mono Audio Amplifier to make sure I had plugged in the cables correctly. And they were. Maybe the speaker was not working since I bought it a year ago. I decided to do a simple test using an UNO.

Well, the speaker works fine. When I googled for solutions, I came across this photo. 

Wait. Why did this person flipped his amp down? And when I looked at mine closely, then I realised, I had plugged in the (-) and (+) the other way round. So that was solved.

Output Synthesizer

Moving Forward :
– Finalize Arduino code
– Finalize and input all the speeches to be recognized in BitVoicer Server
– Output the Bleep censored sound
– Create 2nd prototype of the packaging with precised measurements
– Test laser-cutting
