I've realized Marmara Club on behalf of Hydro control card design you would like to share with electronics enthusiasts. Designing a vehicle iob powered by hydrogen energy, producing electrical energy fed to the battery overheating of the fuel cell by preventing the circuit is cut. The ambient temperature remained around 60 degrees if the first driver is alerted via the buzzer. In the event that the temperature 70-75 degrees accounted master iob control iob relay energized causing the circuit is closed and can be caused by overheating of the fuel cell deformation and the risk of explosion is minimized. Design of the main control unit MC is accomplished by PIC16F877. Buzzer and status LEDs are used for the control of PIC16F84A MCU. Communication iob between PIC16F84A with PIC16F877 microcontrollers are made digitally over a single line. In the case of two different situations not requiring the use of communication iob protocols.
