I wanted to create a couple of wearable devices using the ESP8266 for a SEAWare MeetUp. The first thing I needed was a wearable Wi-Fi access point. My first wearable project would use the access point to coordinate communication between my iPhone and other ESP8266 devices.
I decided to use a lanyard to hold both the battery and a very visible ESP8266 circuit board. I included an 8×8 matrix LED from Adafruit that use I2C communication (needed for he ESP-1). Features included:
- ESP-1 access point
- 3.3 volt lithium ion battery
- 8×8 LED matrix
- 2-position DIP as a power switch
- iPhone to select different scrolling text messages
My next couple of posts will describe the wearable name tag with its OLED display, gyro-accelomter (posture sensor) and IR LED switches.
