For my freeform project in Energy I have been working to consolidate what I learned from replacing the firmware on my Tuya based smart plug into a GitHub repository. I have titled the repo Tuya-Arduino and it is online here.
This was my first time creating a GitHub repository so I have been learning a lot about the process.
As part of the repository I have provided two example Arduino sketches, one that connects to Blynk.io and another to Adafruit.io.
Since receiving the PCBs and successfully soldering the board together I have been trying to rewrite code for the I2C port expander. This has been immensely difficult! The Inkplate Arduino Library makes considerable use of an “Mcp” class, which is written to work with the MCP23017 GPIO expander IC. These chips are quite difficult to […]
The boards arrived! Amazingly within an hour of one another. Based on the experience I think that JLCPCB is a better value. With shipping OSHPark was $55.50 for 3 boards. JLCPCB was $26.36 for 10 boards. Aside from a higher cost OSHPark also left sharp bits of tabs around the edges of the boards which […]
Over the last week I rerouted the traces in my PCB design. Following feedback during class that the auto-router feature in Eagle isn’t very smart I did manage to make some cleaner routing manually. As part of the process I went through each component and made sure they were placed a closely as possible to […]
