Witam,
Mam w zasadzie dwa problemy.
Jest to mój początek z Arduino i pierwszy projekt.
Udało mi się uruchomić LCD'ka i wpisywać odpowiednie komentarze z wykorzystaniem biblioteki HelloWorld!
Znalazłem bibliotekę dla HX711 (wzmacniacz) belki tensometrycznej.
1. Nie mogę znaleźć albo źle szukam podłączenia HX711 do płytki stykowej i arduino
2. Jak połączyć 2 biblioteki aby odczyt z tensometru był emitowany na LCD?

Example using the SparkFun HX711 breakout board with a scale

This example demonstrates basic scale output. See the calibration sketch to get the calibration_factor for your
specific load cell setup.
This example code uses bogde's excellent library: https://github.com/bogde/HX711
bogde's library is released under a GNU GENERAL PUBLIC LICENSE
The HX711 does one thing well: read load cells. The breakout board is compatible with any wheat-stone bridge
based load cell which should allow a user to measure everything from a few grams to tens of tons.
Arduino pin 2 -> HX711 CLK
3 -> DAT
5V -> VCC
GND -> GND
The HX711 board can be powered from 2.7V to 5V so the Arduino 5V power should be fine.

lcd.begin(16, 2);
Serial.begin(9600);
Serial.println("HX711 scale demo");
scale.set_scale(calibration_factor); //This value is obtained by using the SparkFun_HX711_Calibration sketch
scale.tare(); //Assuming there is no weight on the scale at start up, reset the scale to 0
Serial.println("Readings:");
}
void loop() {
lcd.setCursor(0, 1);
lcd.print((scale.get_units(), 1));
Serial.print("Reading: ");
Serial.print(scale.get_units(), 1); //scale.get_units() returns a float
Serial.print(" lbs"); //You can change this to kg but you'll need to refactor the calibration_factor
Serial.println();
