Hi,

I'm making an automatic fish feeder for my aquarium that'll switch on for 10 seconds every day at a set time to feed the fish.

Attached is the circuit diagram I am using. I have tried to explain everything graphically. I'm not sure where I am doing wrong as this circuit isn't working as it intend to.

There's also an YouTube reference link I have provided.

(from 5:08 onwards)

I have taken inspiration from this user and his circuit seems to be working fine. However, his wiring connection is not clear. Can you please help me figure out?
 

Apparently, the YYC-3 timer module isn't providing the intended "pulse shaping" function. You'll either use a timer module with the correct function or shorten the input trigger with a series capacitor.

Wow!! That's too technical for me. Can you please simplify what you mentioned?
