Hey,
I'm afraid that this might be painfully simple, but I really am about as novice as they come with regards to electronics.
I am currently working on a project and I need a little help, I'll try and make it as understandable as possible:

I am currently working on a project and I need a little help, I'll try and make it as understandable as possible:
- I'm making a product that features a reservoir that holds hand sanitiser fluid
- The sanitiser is dispensed when a handle is pulled
- I want a series of LEDs to light up when the fluid gets below a certain level in the reservoir (say the reservoir is 500ml and the LEDs are set to come on at 100ml)
- However, I only want the LEDs to light up and stay lit for about 5 seconds after the handle is pulled
- When the handle is pulled and the reservoir is above the level no LEDs will light up
