Hi all
Need some advice today, I need help in building a small circuit. I have a decent understand of the main types of electrical components, I've done a fair bit of repair work in my time but I've never had to build a whole circuit. (Except for when working straight off a diagram/guide). What I need is a circuit which, when a switch or button of some sort is pressed, a green or red LED shines. I only want one colour to show at once. I can use an LED which is both green and red, in which case I'd need a way to randomly change the polarity or 2 separate LEDs and only one of them to be activated.
What I want to create is a system for when employees leave a building, they active this circuit. Green = okay to go and red = they get searched & their belongings. (Checking for internal theft, each time the circuit is activated it needs to be randomised which colour comes on)
Has anyone built something similar to this and can offer some advice? I have searched around and cannot find a ready made product nor can I find some sort of guide to build something like this. Could anyone shed some light on this for me?
