WIFI + WebServer + Arduino + LED control
Today, I would like to describe how to control LED based on Web server. As you might know Arduino is lower specification than RaspberryPI which means it does not have storage area in order to keep their data. Arduino is more suitable to control prompt data like gathering sensor data. In my solution(Pet Feeder), I have been using EV3 brick for Pet Feeder and Arduino is for getting signal from Pet..
EV3 + Arduino connection via I2C
I was thinking how to connect between EV3 and Arduino without wifi and bluetooth because Arduino board doesn't have bluetooth module and wifi is working on when All devices are connected to AP. Of course I would like to use wifi module to Arduino in order to communicate but I wish the connection of Arduino and EV3 is possible to use I2C or SPI. Both are general communication way and no need to u..
