Here is a system block diagram: Once the load cell is is hooked up to the amplifier, you can hook up VDD, VCC, DAT, CLK, and GND to a microcontroller such as a RedBoard or Arduino board. The portion of code below is copied from the sketch which contains variables you need to know to set up the firmware successfully. . To do this upload the following code on your Arduino board. Load Cells (I recommend only using four wire cells) Resistors (Only if you are connecting one cell to one amplifier) If you are using only one load cell per "Scale" , you would connect it as you say correctly. Dalam tutorial ini kita akan melihat bagaimana menghubungkan, mengkalibrasi dan menampilkan berat pada layar OLED kecil, dan dengan menggunakan rotary encoder kita akan dapat mengubah unit dari: gram, kg atau pound. The range of monitored voltages depends on the selected gain. By connecting the module to your microcontroller you will be able to read the weight on the loadcell. Just upload the Arduino code first (with Labview not open) to the board with the standard HX711 configuration w/ load cell or what ever sensor that uses a strain gauge (I used it for torque). Music was controlled by using Pure Data to read the Arduino board and generate a midi-controller to use in Ableton Live. You probably already noticed some sort of white protective glue over the load cell and four different wires of different colors are coming out, we will later see what is below in this white protective glue. Make sure to edit the calibration constant and zero offset for the load cell in the Arduino code (or set to "1" and "0" respectively it to pull raw .
