Week 1 Challenge – ESP8266 OSC Bridge Demo
After some effort, I have successfully configured the ESP8266 as an AP access point, which also has server capabilities. So once you connect to the AP Wifi with iPhone, you can send OSC message to ESP8266 server port using TouchOSC. Then you can easily relay that message to arduino via serial port in order to control the LED. You can find the Arduino code and more information in my Github repository.
Here is the Fritzing breadborad diagram:
Here is a short demo video:
