===== Week 1 ===== ==== Meeting Minutes September 6,2017 ==== **Attended:Isaiah, Kayla, Rebecca** * Board schematic * Power for the board * Solar charging chip and solar panel * Debugging LEDs * Uploading fix * Bread board problems * Xbee was no longer getting 3.3V * Added a resistor to Vin of the xbee * Now getting around 3.3V ==== Meeting Minutes September 8,2017 ==== **Attended:Isaiah, Kayla, Rebecca** Actions: *Replaced both capacitors (both to 10 μF) *Changed resistor added last meeting from 1 kΩ to 10 kΩ to receive steady voltage of 3.33 V. * Started from square one, and ran through a bunch of different test * Tested by hooking up bare arduino to a power supply. Both 5V into the 3.3V reg and just 3.3V to the whole circuit * Made sure xbees were configured correctly * Sent simple test packets between the 3 xbees using XCTU * Tested the relay using an arduino instead of our bare arduino * After seeing the relay work using 2 arduinos, we went back to using one arduino to send and the bare arduino to relay Current Concerns: *Found that 1 and 3 cannot communicate with each other *Encountered two defective arduino boards *Must add additional LEDs for debugging *Find solution to rid of hardcoding address Outcomes: * Relay is now working properly * Not quite sure what fixed it * Possible reasons: * Xbee wasn't getting enough power * Somewhere in the code got messed up
