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 ..
