In the process of expanding my knowledge and experience with Arduino microcontrollers I’ve taken the base circuit for the welder I created and added sound. To do this I used a small board called DFPlayer Mini. This provides a direct output for a speaker or left / right channels. It also has a mini SD card port for your mp3 or wav files. See the details inside.

These vary from simple leds being turned on, servos activated, audio played, or basically anything you can think of. In this simple setup, I wanted to use a blue led to simulate a welder for a few seconds. I added a push button to start the loop. Check out the full video inside.

I’m trying to keep the momentum going with my new Build It series. Today I completed the painting of the primary parts for the interior of the Walthers Modern Diesel House. I completed the elevated platform and track supports. See the video and exclusive photos inside. Continue reading Build It: Walthers Modern Diesel House 2 – Platform and Track Supports Assembly
