So first and foremost I would like to state I am a bit of a noob to arduions but do have some experience coding, though Im certainly no expert and its mostly in Python. I went back to school last year to finish off an Electrical Engineering degree I wanted to do for quite sometime, so I rather learn and have things explained as apposed just just some one pasting some code down.
Also, I had a profile on here before but couldn’t remember what email i used so i made i new one.
So to the point,
What I am trying to achieve is to create a system that till take inputs by touch screen that will tell the code to pause, start or reset the time and change the timer setting. This will basically send a signal to a relay that will open or close a solenoid to regulate airflow. The timer will count down a charge time(and show it), once “0” is hit it will reset the number and start the discharge timer and open the solenoid, ‘0’ again = reset and close solenoid. “Hold/Stop” will cause the device to either hold the valve open or closed.
[“Button_1”] = Start/Pause #Pressing it each time should cycle it between holding the valve open or closed
[‘Button_2’] = Reset #Will wait for “Button_1” input to start again
[‘Button_3’] = [‘Button_5’] = Increase Timer Value #For Charge and Discharge time respectively
[‘Button_4’] = [‘Button_6’] = Decrease Timer Value #For Charge and Discharge time respectively
Now If I can get a handle on the above's code and get it to work, I would like to try and have UI of the actual number used so that when the user touches one of the timer number/counters they can manual input the desired number as apposed to just pressing an up or down arrow key 20 times (unless theres a way to hold it to have it climb/fall quickly). Also would like to have the "Start/Stop" change color between red and green. Attached a ruff image of what i was thinking. If everything ends up working smoothly I plan on having the battery percent displayed in the corner and maybe even a temp/humidity sensor thrown in. I saw a man (educ8s.tv) on youtube do a nice build I was thinking of following: [link](https://www.youtube.com/watch?v=MWKAitSXv3g). I guess what i was thinking was to write several 'def' functions for each of the timers, then have the 'stop/start' its own function that would reference the timer? The 'Reset' I think would clear the loop function's current setting back to default (10|5) and hold. The up and down arrows for each timer would also have their own function that would be called in the main? Ill forget about the extra stuff until I have a handle on the main concept. The gear I think Im going to used, based of some videos and suggestions would be [UNO R3](https://www.amazon.com/gp/product/B008GRTSV6/ref=ox_sc_act_title_3?smid=AA57DDZKZUZDL&psc=1) and [ ELEGOO UNO R3 2.8 Inches TFT Touch Screen](https://www.amazon.com/gp/product/B01EUVJYME/ref=ox_sc_act_title_2?smid=A2WWHQ25ENKVJ1&psc=1). The raspberry pi setup in the video looks clean and straight forward but looks like a little more expensive route. Ill hold off on buying stuff for a day or two to see if i get any recommendations here. Ill need something to work with because as far as my Google-Fu is concerned I cant find a software online to simulate the components well. So I appreciate the help and the knowledge any of you have to offer; I hope to learn a lot. Thanks! ![Custom MP10 layout.png|552x317](upload://li9MisYMsxyqI0co9Gs0214euD9.png)
