hi folks. I really could use your brain power because mine obviously isn't working. Beware my experience with electronics is limited so please be patient.
I'm trying to run three mini water pumps with certain times. I want to push a singe button and have all 3 sequences run.
1. I need the first pump to run for 30seconds then stop. I'm actually guessing 30seconds. I need a potentiometer in the circuit so I can play with the times until I dial it in. so maybe 10-60seconds with pot. Im trying to fill a container and am not sure how fast it will take.
2. the second pump I need to remain off for 5min 30seconds, then on 1s ,off 1s for 5 ON cycles. so total time duration for this would be 5 min 40 seconds? Astable 555?
3. the third pump needs to run for same as the second pump. Im assuming I can run pump 1 & 2 in series off the same circuit to achieve this.
Since my pumps are variable, I can run the circuits off 2.5-6V. I can really use your guys help coming up with the proper schematic to solve this problem. Thanks for your help and patience. please be gentle.
