For this ENGR 103 final project, my partner and I designed a set of programs to detect steps or vibrations on one ESP32 and wirelessly send a command to a second ESP32 (via a PHP webpage) to turn on an LED when a step or vibration is detected. (Trey's portion of the project) One ESP32 board has a vibration sensor connected to it. This allows the ESP32 to detect vibrations, which it can use to interpret when a step is taken. The ESP32 board is also programmed to connect to the OSU_Access WiFi. If the ESP32 detects that a step is taken, it will post the text "command=on" to a PHP form on the ENGR webspace. If no steps are detected, the ESP32 will post the text "command=off" to the PHP form. (Kevin's portion of the project) When the PHP form receives this text from the ESP32 sensor board, it will output the word "on" or "off" to a text file stored in the ENGR webspace. A second or output ESP32 board is also connected to the OSU WiFi and has an RGB LED attached to it. This ESP32 board will retrieve the text from the file created by the PHP form. This is the command for the LED. If the command received is "on," the ESP32 will turn on the green LED. If the command received is "off," the ESP32 will turn on the red LED. This process repeats approximately every 5 seconds. If the ESP board does not receive an updated command after 2 cycles (approximately 10 seconds), it will flash the blue LED until a new command is received.
