I am building a music box as a Christmas present and need help with the automation.I'm going to prepare a circuit that's hooked up to a battery and a motor so it will automatically play the song.I would also like it to start playing when the lid is opened, and turn off when the lid is closed. How would I achieve this part please? Would it be some sort of pressure sensor? If so, what kind please?I intend for this to be a project of mine so would like to post photos etc as it goes on. Ultimately with a video of the final product. But I need your help! via /r/DIY https://ift.tt/2zMq7mS
