Pneumatic system actuators are widely used to drive manufacturing processes. The actuator movement is certainly controlled by a reliable control system. Various types of control systems are widely used, but they need to be adapted to existing technological advances. Microcontroller-based control system has characteristics that are able to meet the needs. Weaknesses in program writing can be overcome through the step counter method in program writing. Several types of microcontroller-based control systems are available in the market, but to control the manufacturing process, a reliable type is needed according to the working conditions. In order to obtain a control system according to the needs of the manufacturing process, it is necessary to analyze the reliability. The manufacturing process of a drilling fixture has 3 (three) pneumatic actuators and 8 (eight) steps per cycle. This study analyse the usage of Arduino UNO R3 using Dual Inline Package (DIP), Arduino UNO R3 using Surface Mounted Device (SMD), Arduino UNO R3 CH340 G, and Arduino Mega 2560. The output pressure of the compressor is kept at 6 bar. Each Arduino board is tested for 300 cycles continuously. Overall Arduino microcontrollers have relatively stable processing in controlling drilling fixture pneumatic systems with a maximum time response gap of 2,790 s. However, Arduino Mega 2560 in this study has the tendency to increase the time required to run the cycle after 150 cycles of usage. The most stable microcontroller in this study is gain in Arduino UNO R3 DIP and Arduino CH340 G. The temperature data indicates a stable microprocessor temperature at around 25,390 °C and 31,250 °C in overall microcontrollers. The Arduino Mega 2560 has slightly unstable time requirements and higher microprocessor temperature, however utilizing this microcontroller can be used for a more complex input and output system. © 2023 Author(s).
