This week, I was working on improving the quality of the audio output, I have changed a speaker and use DFplayer to store the mp3 file, and play the audio through it. I also use the expanded board to put more buttons and let the button to trigger the audio output.
Next week, I will work on assembling each component and making an actual toy based on them. There will be a teddy bear toy or turtle toy and the board will be put inside the toy. The speaker will be on the head part of the toy and the pressure sensor will be placed on the hand part of the toy. The toy will be divided into different regions with different colors. Users can put blocks into different color regions and they can learn math and color by following the auditory instructions.
