This project utilizes the Wifi module on an ESP32 along with the Publish/Subscribe (PubSub) library on the Arduino IDE to communicate with other Internet of Things (IoT) devices. In this specific tutorial, we learn how to use the ESP32 to communicate with your personal device in a bidirectional way.<br />

|Step_Content=<translate>Before we begin, we need to ensure you have an MQTT broker to communicate and test with. We can download [https://mqttx.app/ MQTTX] (the front-end broker) to ensure communication. MQTT is a lightweight messaging protocol designed for efficient communication between devices in low-bandwidth, high-latency networks. It uses a publish-subscribe model, which we will go over later.<br />

|Step_Content=<translate>Ensure that the ESP32 dev library is installed, then go to libraries in the Arduino IDE and download PubSubClient. PubSub, short for Publish/Subscribe, is a messaging pattern where senders (publishers) distribute messages to receivers (subscribers) without directly communicating with them. Publishers send messages to a central hub (broker), which then distributes them to all interested subscribers based on their topic subscriptions. This is useful to conserve data when trying to share information, because rather than multiple different connections between the publisher and each subscriber, the publisher only needs to send the information once.</translate><br />

{{Tuto Step<br />
|Step_Title=<translate>Prepare an MQTT Broker</translate><br />
|Step_Content=<translate>Before we begin, we need to ensure you have an MQTT (Message Queuing Telemetry Transport) broker to communicate and test with. We can download [https://mqttx.app/ MQTTX] (the front-end broker) to ensure communication. MQTT is a lightweight messaging protocol designed for efficient communication between devices in low-bandwidth, high-latency networks. It uses a publish-subscribe (PubSub) model, which we will go over later.<br />

{{Tuto Step<br />
|Step_Title=<translate>Install ESP32 Development Board & other dependancies</translate><br />
|Step_Content=<translate>Ensure that the ESP32 dev library is installed, then go to libraries in the Arduino IDE and download PubSubClient. PubSub, short for Publish/Subscribe, is a messaging pattern where senders (publishers) distribute messages to receivers (subscribers) without directly communicating with them. Publishers send messages to a central hub (broker), which then distributes them to all interested subscribers based on their topic subscriptions. This is useful to conserve data when trying to share information, because rather than multiple different connections between the publisher and each subscriber, the publisher only needs to send the information once.</translate><br />
