Aero Week 5 Robbie Mc Nally Union College

Aero Week 5 Robbie Mc. Nally Union College Cp. E ‘ 16

The Past Week -ECE 498 Design Defense Presentation -Obtained 2 barometric sensors to test from Professor Cotter -Altitude sensor deflection testing -Obtained XBee modules to test but need shield/headers -Found XBee cheat sheet and tutorials online
