Digital Weight Scale
This project entailed building a digital weight scale that would give us an accurate
readout of a gram value. Our design utilized strain gauges attached to a aluminum bea
m with a fixed end to measure the strain. This strain was then converted from an analog
to digital reading by the use of an AD converter and Arduino Uno. My team and I learned
a lot about collaboration and working together throughout this project. We also each got
hand on experience in our respective fields, as well as learning about other engineering
disciplines. This coding project was very fun to me and was a great introduction into C
plus and embedded systems.
Node Red Wave Form Transmission
This project involved using the board pictured which holds a Raspberry Pi. Unlike
Arduinos has no built-in Analog to Digital converter functionality. At a high level
we were adding this functionality by using a microchip and configuring the serial
perpheral interfaces to connect to this microchip. Also pictured is where I was
actually able to see this wave via WaveForms and on Node-Red. Node-Red captured
this according to its ability (lots of backend to account for) and then displayed
this to an implemented UI dashboard (pictured) in delayed real-time. It was really
interesting to see why this was not a perfectly synchronous wave on Node-Red and
why it read the transmission the way that it did.
