digital Potentiometer meter based digital inputs

[chethankp]

Hi,

I need a digital potential meter to for controlling current flow to the DC load .
I came cross with the below link
https://www.sparkfun.com/products/10613

These ICs are SPI/I2c based since I dont have those interface available now but I have many IO pins available .
Can some body suggest some device/ckt to have a simple digital pot which can be controlled by just IO pins .

even if it can provide 4 levels of resistance value would be good enough ..

Have a look at these: https://www.analog.com/en/digital-t...s/products/index.html#Digitial_Potentiometers

and look for the ones that say "push button" or "up/down".
