1. [**Controllino**](https://www.controllino.com/)

- Arduino, a favorite among makers, had limited industrial applications.

- Controllino emerged to fill this void, presenting itself as the first open-source industrial Programmable Logic Controller (PLC).

- It's available in three distinct versions: MINI, MAXI, and MEGA. Each version is equipped with features like built-in RTC, relay control outputs, and some even have RS485 and Ethernet capabilities.

- Controllino MAXI and MEGA built-in Ethernet chip WIZnet W5100.

2. [**Adafruit IO**](https://io.adafruit.com/)

- Adafruit IO serves as an MQTT server in this tutorial.

- Users can create a free account on the Adafruit site, which allows them to log in to Adafruit IO.

- The tutorial guides users to set up streams and feeds, essential for MQTT communication.

3. [**Visuino**](https://www.visuino.com/)

- Visuino is a software platform that supports Controllino, making it easier for users to develop and deploy complex designs.

- It recently integrated MQTT support, which simplifies communication with IoT devices.

- The tutorial provides a step-by-step guide on how to program the Controllino using Visuino, emphasizing the importance of MQTT in the process.

4. **Photoresistor Sensor**

- The tutorial demonstrates how to connect a Photoresistor Sensor to the Controllino MEGA PLC.

- Detailed steps guide users on connecting the sensor, from wiring to pin connections.

- Once set up, the sensor's data can be monitored and controlled in real-time through a web browser, allowing users to see the Controllino MEGA's LED being controlled and the Photoresistor's value displayed.
