I have a similar project that I'm currently working on where we're applying weight to a truss structure, and depending on whether the member is in tension, or compression, the LED lights will change color depending on the load identified in the S-type load cell. I'm trying this code out and I receive a "no matching function for call to 'HX711::HX711()'" error. I've come across this error quite a few times in other codes I've tried. What does this mean?

Can I use 50 kg range single load cell. Is there any modifications of the code is necessary.

Hi, https://www.circuito.io/static/reply/index.html?solutionId=5da6ee4a9cfabe003054245f&solutionPath=storage.circuito.io I am trying to build the above circuit powered by battery alone. Sparkfun HX711 is expensive and hence I am using Amazon HX711 HX711 module has Operating Voltage: 2.7V to 5VDC and Operating current: <10 mA https://learn.sparkfun.com/tutorials/load-cell-amplifier-hx711-breakout-hookup-guide Sparkfun HX711 has VCC and VDD. VCC is the analog voltage to power the load cell. VDD is the digital supply voltage used to set the logic level. In many cases, you can just short VCC and VDD together. If your microcontroller uses 3.3V logic however, you'll want to connect VCC to 5V and VDD to 3.3V. https://www.amazon.in/Generic-HX711-Weighing-Dual-Channel-Precision/dp/B00OUZCS2Y/ref=asc_df_B00OUZCS2Y/?tag=googleshopdes-21&linkCode=df0&hvadid=396979667742&hvpos=1o1&hvnetw=g&hvrand=2244786411104874136&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9062038&hvtargid=pla-553388600392&psc=1 Amazon HX711 has only VCC and no VDD. Therefore, can I connect LoadCellHX711SF VCC to NodeMCU1 3V3 instead of connecting LoadCellHX711SF VDD to NodeMCU1 3V3? Thanks and regards, Rashmi
