Hi there, I'm a material's design student and I have an idea to a project.. This idea needs an electrical circuit , with a led and a timer, but it has to be really really small, because it is for small objects. How can I mount this type of circuit, with a timer that will fire a red light in the led, after long datas ( from 3 to 12 months). I don't have any experience in this area , so I need to know the materials i need to use, how to mounth and program them.. Can you help me? Thanks !!
