I purchased a
https://www.sparkfun.com/products/10245 Load cell and it has
All the tutorial on the internet shows load cells with 4 wires .
I am not understanding how can i use it ! do i need amplifier ?
If anyone can help please tell me what to buy more so can make a scale out of the spark core (it doesnt have to be that accuate) 20g less or minus is no problem.
Note : I have used FSR they are not accurate at all and the pressure must be above them not like a load cell where the load can be somewhere else (thats how i understand it )
Question: Will a flexiForce be accurate ? better than the normal force sensor . can i use it to scale ?
