The Project was born to pilot and monitor piston cycles. The user can set main data by Blynk app. When the system receives the instruction of a single cycle, the piston starts running. There is also a RGB LED to give a visual feedback, for the operator. Then, data will be saved on the SD card and it could add the possibility to load them online too, using ThingsBoard or softwares like this.
Pratically the system works in 4 steps:
- First Step: the operator has to input instructions using Blynk app ( number of strokes, initial delay and pause between 2 strokes);
- Second Step: when the operator is sure about data, he has to press the "start" button;
- Third Step: the piston will follow given information, and it will monitor what will happen.
- Fourth Step: in the end of the cycle (number of strokes) the piston will stops, and it will be ready to receive a new input.
This project could be useful in automation sector, indeed it is possible to set and to monitor what the piston has to do. It is just a small sized prototype of a larger application in an hypothetical factory. The piston infact could be replaced with another more complex tool, for example a robot arm which can grab and pull or push an object.
It was used compressed air just for economycal reason and accessibility.
WARNING!! It was changed physically the control pin of RGB LED with soldering station, using a cutter to cut the original connection. It is necessary because RGB LED and micro SD Shield uses the same pin (D4), to avoid this problem, we changed the control pin of RGB LED into D8.
