I'm working with some kids on a school project. They want help with a simple circuit design. Bare with me as I explain this. My circuit design skills are VERY basic.
We will have 3 momentary switches (1 2 3). If they are pressed and released in the order of 3 2 1, we need it to trip a relay and keep it tripped for about 4-5 seconds. Any other order and the relay stays closed. Also, there should be a reset timer such as if 3 and 2 are tripped, but nothing happens in x seconds system resets. This will be running off of 4 AAA or 4 AA batteries. This device will be used for 5-10 minutes at a time. I'm trying to keep it basic as possible. These are 6 & 7 graders with zero electrical knowledge. If the circuit get too complicated, their eyes will just glaze over. I was thinking about something with capacitors. I know they store and release energy and have some timing specs. -- Thanks, Mark mailto:m...@mailmt.com Myakka Technologies, Inc. www.MyakkaTech.com Proud Sponsor of the Myakka City Relay For Life http://www.RelayForLife.org/MyakkaCityFL Please Donate at https://secure.acsevents.org/site/Donation2?df_id=1011305&PROXY_ID=1645865&PROXY_TYPE=22&FR_ID=57644 --- This email is free from viruses and malware because avast!
