In this project, the PCB design and electronic board schematics of the control header board for the control system of the condom testing machine were created. In addition, the programming of this PCB was carried out in the C/C++ language in the Keil µVision software programming environment. This control header board based on ARM-NXP LPC1788 microprocessor is designed and built for the control system of sanitary condom testing machine. Since there was a need for a control system with high speed and accuracy in the condom testing machine, this header board was made for this machine and was tested. In condom manufacturing factories, it is necessary to test condoms for the absence of holes after initial production. This test is carried out with an electronic testing device or ET. The basis of this device is to create a high-voltage circuit. If the condom has a hole, a short circuit occurs in the circuit and the device rejects the condom.

In the control system of the sanitary condom tester, the header board based on the ARM-NXP LPC1788 microprocessor is placed on an interface board, which contains a number of relays and SSRs as well as interface drivers for the high-voltage part of the device.

In the figures below, various parts of the schematic and PCB related to this project are shown.
