Helo i am a new member inn this forum, and have a smal problem (for You) i would like to have hjelp with.
I am an instructor in dog avalanch rescue and have biuld a robot for training purpose.
In short terms it works like this.
I dig down a box, whitch i Can remotely turn on/off severel aids for the dog.
My problem is: i Get a controll signal, that shows me if the aid is on. But i Can only send one at the time.
Therefor, Can someone help my construct a circuit that starts when a rele (rele) is turned on (both NO and NC) and stay on for like 4 secunds (used to send the controll on signal). Then turn off (goes to ground). And when the rele is released a new 4 secunds is giwen (controll signal off) it Can take up to 20 min before its turned off.
I have 12 v
To make it more difficult, there are 4 aids tatt needs this.
Best regards
