The Story Imagine working at the office from nine to five punching numbers in a computer the whole day...All you have to hold on to is your coffee break! Fortunatly, it is not that black and white for most people. We do have something in common though. There is a time that each and everyone of us needs to take a bathroom break. At some point, all the coffee we drink needs to leave the body, doesn't? So you are on your way to the comfort room as you where holding up every drip of coffee while finishing up that report. You're in a hurry because you 'need to go'... When you arive at the cr, you rush to open the door and you are about the enter 'the little zone'. But, what is that smell? My goodness, who burried there dead cat in here? That's really nasty!!!!
You get the picture right? I had an artist sing a song about it for me. You can listen to it here....it's attached. If only there was a way for the previous visitor to leave a notice.... Well, There is now! This talking CR Timer. will indicate the level of 'danger' using some leds and on top of that, it plays funny sounds at each level. When the visitor is done doing his thing, one can press the button on the CR timer to give an indication of the 'danger' to however is visiting next. It's a timer, so it will count down. The level will automatically move doen a nutch, every three minutes until, after the lowest level of danger, it will shut down.
What do you get? This is a PCB with all SMD/SMT components. You need to add a Arduino Nano, A BC547 (or a simular transistor), a speaker, a string of 5 pixelleds ( WS2812 or simular). If you want, you can also add connectors. And yeah, you will need a battery or power supply (9v) There is no need for a power switch.
