Analog input


for whatever reason – i don’t have pix of my digital in, but learning from the past here are two images of projects i did that week.

first is my analog in using a dc motor in reverse. my hand turning it, thus generating a current between 0 and 1 volt, and feeding it into the analogue input pin on the arduino, i was able to light up a string on four LEDs depending on how much current is produced from the motor. analog-in1.JPG


That Wednesday i put together a counter for my adv. micro-controller class. the image only shows the seven segment counter part, but i’ll attach another w/ the pic circuit on there. It receives IF signals from another board and displays the signals as numbers 0 -9.
