I have been asigned a project for wich i have to desing a circuit that includes:
-A START button
-A STOP button
-A +(or up) button
-A - (or down) button
-Two 7-segment displays
-An electronic valve
It must do the following:
The user controls the time (in seconds) in wich the sink will be open through the + and - buttons. They add/sustract 1 second respectively. Then, they press the START button and the sink should open for the time previously indicated. If the user desires to close the sink before the time is up, they should press the STOP button. In doing so, they also reset the timer. If the user presses the START button without giving an amount of time, the timer will count 15 seconds by default.
I was thinking i could get a 27VDC solenoid valve, since it is easier for me to work with "low" voltage
The things that are giving me a hard time are:
-making the clock, as well as making the exeptions for the clock (example: Stop button, Start button default time). I have been looking up schematics and experimenting on my own, but i can´t seem to find a way to make it without it taking a lot of space in the PCB (although that could be due to poor PCB desing on my part).
I´ve managed to make an ascending clock (Pic attached), but not much else.
Note:
-All of it must be done without any coding
-The software i use for making my desings is Altium Designer 2018
-The software(s) i use for simulation are Livewire and Circuit Wizard.
Thank you for reading and any help you could offer would be greatly appreciated.
I apologize for any grammar error or bad posting practices, i am new here and English isn´t my first language
