Have you ever wanted to control hardware outputs remotely with just the press of a button on a webpage? With the ability to create a web server and connect to it, this project allows you to design a simple button functioning as a momentary switch, enabling remote interaction with the Blink Board’s outputs—perfect for IoT and automation applications

GSM modules like the SIM800 are compact and cost-effective devices that bring mobile network functionality to your projects, enabling tasks such as making phone calls, sending SMS, and even accessing the internet via GPRS. When integrated with the Blink Board, the SIM800 module can be used for applications like emergency alerts (sending SMS during critical events), remote control (sending commands via SMS), and monitoring systems (calling specific numbers for notifications), all controlled via AT commands through a serial connection.

By sending Bluetooth commands via a Bluetooth terminal app on your smartphone, you can remotely toggle a relay for applications like remote light control, home automation (to control appliances such as fans or motors), and security systems (to activate or deactivate systems remotely).
