This paper is presented a simple and amateur prototype of shear force testing apparatus machine for the education training kit purpose. The prototype was based on the Wheatstone Bridge network principle and applies in S-Beam load cell. Shear force on the beam is calculated and obtained by processing the change range of output voltage of the load cell sensor via microcontroller (16F887). MPLAB XC8 compiler is used to compile the C code into machine code while PICKIT3 is used to load the machine file into microcontroller. INA128P amplifier op-amp is used to amplifier the signal due to the output of load cell is in millivolt. RC passive low-pass filter is used to filter the noise. Graphic User Interface (GUI) and LCD are used to display the total shear force for the verification. The experiment results have shown a significant polynomial second order linear in analogue output data proportional to the loads.
