Digital Taste Interface? Answered
Hello Instructables. I had a question for my newest project. I am looking to make a Digital taste interface with Arduino like this http://www.nimesha.info/digitaltaste.html#dti. The video says that the current needs to be altered between the range of 10 and 140 microamps. I have bought a 10k and 100k digital potentiometer, as this was my first idea. Does anyone have a better idea as to control current at ranges that low?
