I am a beginner at Arduino which I just received in the mail. My understanding is my Arduino Mega has 54 digital inputs and 16 analog inputs making for 70 inputs all together. I would like to track pressure sensors which are configured to detect simply open or closed. Given I can use my analog inputs as digital inputs can I have 70 pressure sensors? My project differs from others in that I dont need to track a gradation. In regards to the mega wiring what can I do to achieve this? Will I need a separate breadboard for each pressure sensor?
