I made a similar project using the same components for a sky (sky with 60 leds + cloud with 60 leds) and the DFplayer, simulating thunders and rain with the leds
Hi,Yes I made some videos:Youtube channelAnd a blogI was impressed of the power of the Arduino Mega, I attached a lot of devices on it. Since it is in the Kids room, I didn't wanted any wireless devices, so the BT will power off automatically after 5 minutes if not used.If you want download the code you can check this:https://hackaday.io/project/13143-roomskyBut I used the DFrobot device too in this project. In a project like yours I would use the WT588D, since you just jave 5-10 waves and each has only 5-10 seconds.
Great project!I'm wondering about the MOSFET. What does it do? I'm new to building circuits, I'm building a project were Christmas lights are blinking to music. I can get it to work, but when only a few lights are on, I get a lot of noise in the speakers. Maybe I'm missing a MOSFET? Regards
