The GERI Gadget is a small smartwatch I made for students taking my Biomedical Instrumentation class during GERI Summer Residential 2018. GERI stands for Gifted Education Resource Institute and it's a wonderful group at Purdue that specializes on educational policy, training, teaching methods, etc. of gifted students in K-12. Check out all their wonderful work on their website: Purdue GERI
Anyways, I wanted to create a device that allowed students to get hands-on experience building some sort of Biomedical device. This meant adding enough peripherals so that students could make anything from a pedometer to even a fall alert. Revision A of the watch contains a few peripherals, namely:
- ATSAMD21 Microcontroller
- On/Off Switch
- Battery Charging Circuit
- OLED
- Two pushbuttons
- Buzzer
- Photoresistor
- LED
- LIS3DH Accelerometer
This section is still under development. I will be filling it out over the next few weeks so bookmark this page and stay tuned!
You will need three libraries to get started with the GERI Gadget:
- Adafruit's SSD1306 Library
- Adafruit's GFX Library
- SparkFun's LIS3DH Accelerometer Library
