Day 26: Todays lab was introducing u to real time telemetry and the MPU 9255. The real time telemetry module is often used for quad copters and is a fairly inexpensive option for seeing what is going on as its happening. a simple usb connection to the computer, RX and TX connection on arduino with power and ground, and this module is simple to setup. One other necessity is to download another serial monitor to be able to see live data stream onto your computer.

The other portion of the lab was to setup up a MPU9255. This sensor is a 9 axis MEMS sensor with an integrated BMP 280 pressure sensor. This module can read acceleration, gyro, and magnetic field in 3 directions along with the pressure and altitude. My lab partners had success in getting both the telemetry and also the MPU9255 to work and sen back data to the serial monitor. This was critical portion in our project to be able to get and record data for the flight of our rocket.

After the lab we began discussion on Complex class with overload operators. Professor Mason began to talk about complex number and also complex roots for the quadratic equation and thats where i began to get lost. At this point in the class i began to put most of my focus on project 3, which was getting the rocket payload to work properly with my lab partners. Matthew and Richard both tackled the coding while I worked on building the rocket we would launch and also the hardware soldering and packaging of our arduino into the rocket payload section.
