Automatic beverage dispenser

This automatic beverage dispenser
project, based on the Liangshan School of Divine Skills, originated from a small idea in daily life. When making honey, it often gets sticky everywhere, so I wanted to create an automatic honey dispenser.
It has two relays, one input and one output. The input relay
is connected to the water pump of the water dispenser
; it closes when water is dispensed.
The output relay connects to an air pump
, which pumps air into the dispenser.
Another tube
dispenses the honey. For programming , use
an online editor (Ctrl+O),
select the attached package,
compile and link, then burn the program.
You can also use Keil.
Regarding compatibility with water dispensers,
I suggest using a modified water dispenser.
After purchasing, measure the voltage of the water pump;
buy a relay of the same voltage as the pump and install it on K1. My
3D model
design is terrible; please create your own. The larger
the air pump, the better ; 12V is sufficient.
