One of our students at the Career and Tech Center worked with volunteer Norm O'Foran to make a BOB as part of his science fair project, featured a floating marsh. The videos below show parts of the building process.
The student is connecting an SD card data logging board to the BOB, which allows the unit to collect data on an SD card in case our cellular communication fails.
After wiring all of the sensors, the student and volunteer must verify that the new equipment is communicating with the microcontroller.
