Hello to All,
I am working on one college project but fail to complete it due to some coding issue.
As im new to coding and trying this project from last 2months but still im stuck.
Everyone please suggest were im wrong in coding and how it can be made .
My project is concern about the pressure sensor and pump .
1-i want to set the pressure level with button1 and button2 which will display on LCD......Which i have done.
2-after that i will press button4 to set the ON and OFF time to run the motor.once time is set i will press button3 and process start. which i am not able to do.
i want to set the time duration in Minutes .
I am attaching my schematic of project......and code below.
Please please help,teach,suggest......
