[Electronics] DIY Audio Melody Batman Lights

Two days ago, I watched someone make a Batman lamp, and then I did one myself. It was boring. I was empty and suddenly wanted to have an audio melody lamp. So I bought a board in the mall and connected it with an abandoned plaque. The production process was not taken. At that time, the mobile phone was out of power. In fact, it was very simple. I painted two pictures and I should understand it. The one on the board is sensitive.
