5. Design Challenges Controlling many high current devicesControlling many high current devices –This was solved by using a two stage power supply (on the PCB) and using large, isolated traces on the PCB Bluetooth ConnectivityBluetooth Connectivity –We resolved our issues through methodical debugging and by establishing a connection via OS system calls. Weight & temperature conversionWeight & temperature conversion –We used large-gain linear models and running averages of sensor data.
