This is our second and likely final demo of our project working with the vast majority of its functionality. The biggest jump from the last demo was integrating our entire system’s components (MSP430, sensors, passive components, power regulation, etc.) onto a PCB. Here is a close-up of the PCB without the front cover of the […]

This was our first test of the majority of our system completely hooked up and running. It shows the window opening and closing based on temperature differences, air quality, rain, and obstruction detection. We have designed a PCB to encapsulate all our components, but it won’t arrive until after we shot this video, so for […]

In this update, we successfully configured the MSP430FR6989 Launchpad evaluation board to communicate with an A4988 stepper driver to run a NEMA 11 stepper motor. The stepper motor has a 27:1 gearbox on the output, which results in the input shaft having to turn about 27 times before the output shaft can complete a full […]

For this update, we successfully setup the MSP430FR6989 Launchpad evaluation board to read voltages from an analog sensor, in this case a light-dependent resistor (LDR), and display information on an LCD using SPI. For the analog sensor, we setup a simple voltage divider circuit between the LDR and a 1 kΩ resistor. The MSP430 uses […]
