    I’m looking to make a smart controller that can integrate with 12v compressors for inflating tires on off road vehicles. Mainly I need the the pcb and electronics designed and I can make the housing and everything else. If you would also want to design the housing in ok with that. Needs to be almost waterproof. Mainly splash proof and heat resistant. It will be mounted in the engine bay. As far as the controller goes all it need to be able to do is check pressure from a pressure sensor that will be connected in line from the compressor and control a 12v output source(5a at 12v) to trigger the compressor to turn on as well as for deflating need a valve to be controlled to air down to set pressure. Looking for keep it as simple as possible. Only gonna need a...

    Hi there, I'm looking for an expert in Arduino programming who can develop custom code. I have all the hardware including an Arduino Uno R4, a NEMA 17 stepper motor, an A4988 stepper motor controller, an RC522 RFID antenna, a 1602IIC LCD display, and push buttons. All of these components need to be connected to the same arduino. I need this system function as follows: - When the push button is pressed, the stepper motor will be moved X amount of steps in one direction after a delay of 1 second. At this time, the LCD display should display "Scan ID to Unlock". - When a registered and accepted RFID tag is scanned, the LCD will display "Tool Unlocked". When this happens, the stepper motor should be moved X amount of steps BACK to where it came from. - If ...
