Building sensors with Joel

Using Arduino to get the cost of probeware down (for science education).

 

Vernier's cheapest interface is $61 and handles one sensor: www.vernier.com/mbl

 

Arduino Uno is $30 and has 6 analog inputs: www.sparkfun.com/products/9950

 

Our goal is to interoperate with this curriculum: www.concord.org/activities/research-focus/probeware
