Currently i am in a group project where im building an Arduino torque wrench. To my best understanding we are gonna install two strain gages on a 1/2 inch drive extension and connect the strain gauges to a SparkFun Load Cell Amplifier - HX711 (SEN-13230) where the torque will read out on a Basic 8x2 Character LCD - Black on Green 5V (LCD-11122). We are going to integrate a Vibration Motor (ROB-08449) and a Piezo Speaker - PC Mount 12mm 2.048kHz (COM-07950) so when the wrench gets to the desired torque then it will vibrate and beep at the same time.
can anyone point me in the direction of finding the right strain gauge to install on a 1/2 inch extension????????
any additional comments or suggestion would help me a ton.
