Hi all,
I need to design a circuit as part of a STEM project for kids and could use some help. Basically I need to create a board with a simple diagram of an Oil and Gas process plant, this will be split into 3 ‘zones’. As part of the activity we have 3 ‘alarm/emergency situations’ for each zone- Gas Detection, PW/HC Leak & Fire/Heat. For each zone there should be 3 green LED’s and 3 red LED’s. We want only the Green LEDs to be on to start the activity to simulate that the plant is operating normally. We then want to simulate emergency situations by switching from the green LED’s to the red LED’s, not all at once but one at a time as the activity progresses and depending on which ‘Zone’ the kids are working.
Does anyone have any ideas on how to create this? I would like to keep it as simple and cheap as possible and safe of course!
Please see the very crude sketch for info.
