I'm designing a data acquisition system for my school's ASME club hovercraft. I'm a novice with Arduino, but have some electronics knowledge, and it is usually not too hard for me to pick up. Here's my question - I'm trying to figure out a way to hook up the arduino uno to a datalogging shield, have a 16x2 LCD, and use 5 analog inputs, and 5 digital inputs and one digital output. Is this possible? I think I have enough pin outs, and we're only going to be sampling every 2 or 5 seconds and writing to the SD card. For analog inputs I'm looking at pressure sensor (for the hovercraft skirt), a pitot tube sensor (fan velocity), steering angle, and 2 axis accelerometer. For digital inputs I have a dead man switch (connected to digital output for engine shut off), 2 RPM sensors, and 2 buttons to change LCD display. Will this work? has anyone attempted anything close? How many dedicated pins do the datalogger shields need, and how many for a LCD display. I'd think with a low refresh rate i could get away with a shift register controlled LCD and use only 3 or 4 pins. But what about the Data Logger?
