Updates!!

All electrical components have been soldered to the board, and retracting was required due to an unseen error in initial schematic design. Initial programming and testing has begun and the ADC and IMU appear to be in working order.

The corrected schematic can be seen here.

When programming began for the Transmitter and Receiver Modules, we encountered some issues when trying to get the devices to communicate. When looking at the data output through an oscilloscope, it appeared that the data was being transmitted but not received. However, this turned out to be a simple fix - we needed to pull the reset pin high and the sleep pin low. Now wireless communication is working as it should be.

Another slight issue we are having with the transmitter board, however, is that the program seems to be resetting itself every so often. Right now we are unsure what is causing this issue, but this will need to be fixed prior to initial launch.
