Servo module
This laboratory is located in the office of ITT Group in Tallinn, Estonia.
Introduction
This laboratory can be used to practice controlling the servo motor attached to the controller.
Prerequisites
For this laboratory, the student should understand basic MQTT concepts like topics, broker, subscribing and publishing.
Technical details
This laboratory consists of a servo with the add-on module attached to the ITT IoT controller module.
Sensors
This laboratory does not have any sensors.
Specifications
Table 1: Servo specifications
| Specification | Value |
|---|---|
| Speed at 6V | 0,07 sec/60° |
| Stall torque at 6V | 0,042 N-m |
| Speed at 4,8V | 0,09 sec/60° |
| Stall torque at 4,8V | 0,028 N-m |
Electrical connection
The signal lead of the servo is connected to D3 pin of the controller.
Software, libraries and externals
- ITTIoT libary - used to program the controller module.
- Servo libary - used to control the servo.
Communication
The user can connect and program this controller using the Distancelab environment.
Limits
At the same time, only one user can program the controller. But all users connected to the Distancelab MQTT broker can subscribe and publish to topics specified.
Hands-on labs
List study scenarios (hands-on labs), linking to the Dokuwiki pages with hands-on labs descriptions (there should be a separate page for each scenario). Classify each scenario and refer to the target group using starting keywords: * Beginners * Undergraduates * Masters * Professionals Note, assume that more professional group automatically contains less professional ones. Note - use language and as appropriate to the target group, i.e.:
* Beginners: Elementary operations on the Arduino 2x16 LCD screen. * Undergraduates: Visualizing temperature and humidity on the remote screen. * Masters: Using power saving states to limit power consumption.
Support
Give some information on how to access help, how to get support in case of the trouble etc.
