please tell me that does it work from back too
and is it okay as a cat door

[@amirasenussi2755]

could you list all of the materials to buy please.

[@ccoinchris1905]

Would this system work if i used a servo motor instead of the door you used?

[@EEWave]

Yes, this will work. I've uploaded a video on "servo motor controlling by 555". No microcontroller. I hope that video will help you.

[@vophuc491]

could u list all the components please. Sorry for my bad english

[@josephngao4570]

Can i get a pcb layout for the motor control please

[@kalieldesilva531]

Where are the products for all these D.I.Y. videos

[@EEWave]

For the construction of the door, please watch first video of this series. Video link in the description below.

[@samaragiri]

Can give any idea..when door is closing and pir sensing it should open at the middle without close..thanks

[@JonnelKlaineDollente-vo8um]

can this be run in 12v or 9v battery?

[@lesley04]

can you give a circuit diagram please?

[@crazyspace5964]

what if the trigger signal is non repetitive??

[@amberaboulfaida-xo3fr]

What kind of 7404 IC are you using? We got the SN74LS04N and can’t get the circuit to work. Help!

[@amberaboulfaida-xo3fr]

Also, what volt battery did you use? I know the diagram shows 6V, but I could only get some function with a 9V battery. Do I need to increase?

[@EEWave]

7404 is NOT Gate IC, 7404 can't handle 9 volt. I think your IC got damaged. Instead of 7404, you can use CD4049 or CD4069. both of them are NOT Gate IC and can handle up to 18 volt.
