What's this?

• It's pedestrian signal controller running on ESP8266 (aka ESP-WROOM-02).
• I made custom schematic and artwork from scratch.
  • Use EAGLE 8
• I wrote sequencer code by C++ on ESP8266-Arduino IDE.

Video

• We record our discussion into YouTube: Fun with Pedestrian Signal (In japanese)

NT NAGOYA 2018 conference (2018/10/6)

• We did public and demonstration the MatrixSignalController.
  • It uses with the ExtremeFeedbackDevice's signal box.
  • The three boxes chatting with independent WiFi network, we use http api server and client library.
  • See the "MatrixSignalController" folder at repository.
