Once I test it on my vehicle’s parking sensors and everything works well, only then I will release the payment to you. At the end you must also provide me everything I need for making additional devices, including: Schematics, Gerber files, Parts List, Detailed instructions for assembling the device, and detailed instructions on how to program the device. You must use electronic parts readily available on You must also make the device to be programmable using the microchip pickit2 programmer (this is the programmer that I have). Please let me know if you have any other questions.
