Hello people,
I am trying to use my finger as a button. I am using two contacts one being the ground, and the other one being connected to the arduino's digital input along with a pullup resistor. I very roughly calculated my finger's resistance and its in the range of megaohms at 5volts (around 2.5Mohms). The problem is that at that kind of resistances, the pullups must also take huge values (>6 Mohms) in order for the pin to go low. This method also implies noise. Is there a better way to do this? Enlighten me please
Thank you in advance
Have a great great day
