Or is it a load hell?
Hi,
I'm trying to setup a simracing pedals set, but I'm having huge trouble getting the brake (based on a load cell) to work.
Components:
- Arduino Leonardo R3
- HX711 module
- 150kg Load cell
Wiring:
- HX711 VCC --> 5v
- HX711 SCK --> Pin 3
- HX711 DT --> Pin 2
- HX711 GND --> GND
I got several HX711 (I'm troubleshooting this for a while now...), and I get wildly inconsistent results
I run the HX711 library Basic example code:
#include "HX711.h"
// HX711 circuit wiring
const int LOADCELL_DOUT_PIN = 2;
const int LOADCELL_SCK_PIN = 3;
HX711 scale;
void setup() {
Serial.begin(57600);
scale.begin(LOADCELL_DOUT_PIN, LOADCELL_SCK_PIN);
}
void loop() {
if (scale.is_ready()) {
long reading = scale.read();
Serial.print("HX711 reading: ");
Serial.println(reading);
} else {
Serial.println("HX711 not found.");
}
delay(1000);
}
Load cell not connected at the moment, only HX711
HX711 number one:
I mostly get "HX711 not found" (when first connected, I got some "HX711 reading: -1", but after a while, I only get "not found"
HX711 number two (same board, same wiring):
3 times HX711 reading: 0
2 times HX711 reading: -1, then "not found
HX711 number three (same board, same wiring):
HX711 not found
HX711 number four (same board, same wiring):
HX711 reading: 8388607
I tried connecting the load cell at that point, but it changes nothing... the reading stays at 8388607
I'm really desperate, I find myself with 5 loadcells, 3 arduino boards, 4 HX711 amplifiers and despite my best efforts, nothing works.
If you can help, I would be really grateful (even just telling me what an HX711 connected to an arduino SHOULD return... 0, -1, 8388607?)
