I am developing a remote control of G-gage train model by TOSHIBA FlashAir and Arduino (ATmega328).
A motor of G-gage train model is controlled with PWM of ATmega328 and a full bridge motor driver (TOSHIBA TA8428K).
My iOS application to remote control is made with Xamarin (C#). My iOS app can control of speed and select of direction of running.
There are my remote control units with FlashAir and ESP8266 in my photos. Right side is a unit of this project, left side is a unit of my other project.
FlashAir is the SDHC memory card with embedded Wireless LAN functionality.
