Last Modified, needs comments for each line so I can understand what is happening I.E, when a light sensorĪdapted from code by Ben (thewag on Trainboard) pieced together from multiple sources, including Toms Trains and Things, original idea by fernpoint on Model Railroad Hobbiest, and suggestions from Marc, an actual career professional welder. Interrupt driven sensor should only play on a RISING edge single. XX seconds after cycles is shutdown, the MP3 File 5 loops 41 seconds until next trigger Grinding the weld smooth (2 yellow leds flashing with MP3 File 4 grinding sounds) Hot Metal Afterglow (red led fading no sound)

Welding (white and blue leds flashing with MP3 File 1 welding sounds) MP3 File 5 for 41 seconds of old time radio music after trigger event Script for Full Featured Welding Simulator w/Sound: The whole sequence repeats once more, then stops, and everything goes silent.Īfter a short time, the old time radio music starts playing again, and loops until the next trigger event. Then the wire brush sound file plays to simulate cleaning up the slag, and stops.Īfter time enough for the guy to put down the wire brush and pick up the grinder, the 2 yellow LED's start to flicker grinder sparks, and the grinder sound file plays for a random time. Next the slag chipping sound file plays, stops, and plays again. This time is enough for the welder to pick up his hammer. When the welding stops, the red LED comes on and fades to simulate the hot metal afterglow, no sound. Music continues for a while, then white and blue LED's flicker to simulate arc welding, and the arc welding sound file plays for a random time. My sketch plays old time radio music, looping until a trigger event, from a switch or motion sensor starts the sequence. If you copy all 5 at once using Windows, they will get loaded in jumbled order, like 5,1,2,3,4. The sound tracks were named 0001.mp3 through 0005.mp3, and must be loaded one at a time in order. The sound effects were recorded from YouTube videos using Audacity. This one could be built for $8-15 depending on where you source your Arduino Mini, LED's Resistors, TF Chip, Speaker, and DFPlayer. I have found all kinds of welding simulators on the web, and wanted a full featured one, with sound, as cheap as possible.
