Control de Temperatura Usando PID: Construcción del Prototipo.
Introduction to Building a Prototype
In this section, the speaker introduces the video and discusses building a prototype for less than $20 to demonstrate how a controller maintains the temperature of a focus at a set-point.
Building the Prototype
- The components needed include an LM35 temperature sensor with three pins (yellow for power, green for signal, blue for ground) connected to Arduino.
- Additionally, a dimmer is used to control the energy sent to the focus from Arduino.
- Connections are made with attention to color-coding: red for power, black for ground, purple and white cables for electrical connections.
- Specific ports on Arduino are utilized for different connections such as 5V and ground.
- The prototype is mounted on a wooden base using specific cable connections.
Sensor Placement and Optional Fan Addition
This part focuses on sensor placement near the focus and optionally adding a fan for disturbance response.
Sensor Setup and Fan Addition
- The sensor is positioned close enough to sense temperature without touching the focus directly.
- An optional fan can be added to facilitate disturbance response but is not essential.
Conclusion and Next Steps
The video concludes by mentioning future tutorials on programming Arduino to gather sensor data.
Final Steps and Future Tutorials
- Once assembled, connecting Arduino via USB allows interaction with the prototype through programming.
