An IoT project developed with the help of NodeMCU to detect changes in any two currency systems with notification application for android.
The ESP8266 connects to the internet via Wi-Fi and grabs the Forex Rates every 10 seconds. Based on the movement of this value, it sends a UART message to the Arduino Uno (Rise/Fall/Unchanged). The NodeMCU receives this UART message and accordingly lights up an indication LED (Green/Red/Yellow).
