This week before class time, our team prepared for the interrim demo by finalizing the work we’ve done separately and present them in a working form. This includes the LED circuitry worked on by Emily, the data collection and signal processing by Albany, and the software interface with sensors by Jason. Overall the demo went well, with no major problems.
After the demo, Emily and Albany went to Schenley park to take some measurements with the sensor as part of the next round of testing, with the goal of getting more detailed data. The results showed us that the specs given by the manufacturer of the microwave sensor were not correct, as we were only able to get about 10m of usable range, which we will investigate this week.
Progress has also been made to the power circuitry, enabling the lights and the microprocessors to be run off battery, and the software, fixing a problem with data alignment and enabling the I2C master bus to communicate with the LEDs. We will work to start integrating the components next week, and iron out any bugs that appear in the process.
