I’m startting a new project and was told arduino is best for making my own micro-controlled stuff
It’s basically a countdown-clock, and it’ll be started by supplying power and shut down by stopping the power supply, is that okay for an arduino board, or does it need a proper shutdown?
Additionally there are four seven segment displays needed (I found this one: http://www.conrad.de/ce/de/product/160134/7-Segment-Anzeige-Kingbright-SC23-12GWA-Zifferhoehe-57-mm-Gruen-24-mcd?ref=list) and a couple of control elements.
I’m still searching for a “wheel” to set the time and also a small button to start the countdown.
The clock should also feature about 20 LEDs which show the time left.
So I’m searching for the control elements and the right board to get started, please help me
(I’m sorry for any cases of bad spelling, german-autocorrect is not exactly helping)
