I am in a beginner electronics course at jr high (9th grade) and am really liking it. We have learned about resistors, diodes, potentiometers, LED,s, transistors and scrs etc. Our final project is giving me trouble so I have been looking and looking and havent found what I'm looking for.
We get bonus marks if we can figure it out.My assignment at school has two parts to it:
1 to add a delay on circuit to a alarm circuit which uses an scr so that you can get out of the room without it going off. We are only allowed to use capacitors and resistors, etc., no 555 timers or IC's.
2 to add a delay circuit that lets you go in the room so I can shut the alarm off before it is triggered too.
The worst part is that I only have until christmas holidays to get it done.The class is really cool, I like my teacehr and I want to learn more. My knowledge is very limited. Any ideas?
