Everyone has someone they miss. Maybe it’s distance, maybe it’s conflicting schedules, but seeing loved ones in adulthood is hard. If you miss someone and want to get love and spread some love, here’s how! Instructables Link
SHOPPING LIST
To make this project, you will need 2x of each:
Electronics:
- Adafruit MPRLS Ported Pressure Sensor Breakout – 0 to 25 PSI
- Adafruit ESP32-S3 Reverse TFT Feather – 4MB Flash, 2MB PSRAM, STEMMA QT
- Lithium Ion Polymer Battery – 3.7v 2500mAh
- Silicone Tubing for Peristaltic Liquid Pump – 1 Meter
Fabric:
Plus these tools:
- Soldering tools and supplies
- Silicone adhesive
- Hot glue gun with glue sticks
Circuit Diagram
The Adafruit MPRLS Ported Pressure Sensor Breakout and Li-ion battery are attached to the Adafruit ESP32-S3 Reverse TFT Feather.
Attach Tubing to Sensor
Make sure to use a silicone adhesive when attaching the tube to your sensor, because the only thing that makes silicone stick is silicone.
I personally had a lot of trouble with this one. The first one attached like bread to butter, perfection! The second tube on the other hand….. Messy.
Connect to Arduino IoT Cloud
In order to connect my board, I created a boolean variable for my Thing through the Arduino IoT Cloud. By inputting my network and device information within the code, I was able to connect.
Patterns & Sewing
For the patterns, I was originally going to make a stingray and an octopus, but due to time constraints, I am going with my mom’s favorite shape, a triangle!
Genuinely making the pattern to sew for this was pretty intuitive. I just cut out two large triangle pieces then cut out the strips that go in between the two triangles to create volume.
