Description
Experience Level: Entry
Hi there. I have a little Arduino project.
A controller which attaches to a framed picture. Once someone gets within 2 metres then an audio file is played. As the viewer gets closer the sound gets louder (and quieter as they move away. It must be able to accept micro sd cards. be battery powered. Mono only. WAV files preferred, but mp3's may work as well.
Need parts list (<£10 preferred), circuit diagram (fritzing for example), and arduino sketch.
EDIT: using HC-SR04 and DFPlayer_Mini please!
