My latest project is a cabinet used for drying and curing 3D printed resin parts. I planned on using Adafruits 16x2 LCD 5 button shield on an UNO R3. I have fiddled with States for a couple of days trying to find a way to input times from 5minutes to 20 minutes with the keypad, hit the select and …

[image] scrapheapind: but cannot wrap my head around what or even if this can be done on an Arduino. Why begin with such complications? Use a regular 2-line LCD. Use a regular keypad with 10 numeric keys plus 1 key to identify which value is being entered, 1 key to be an enter key and 1 key…

Sure it can be done. I see +/- buttons for fan speed, a single input for the door, and a relatively simple LCD interface, all can be cobbled from the examples here; Bob's input code will be the most complex, but well worth it. Fan output - you'll likely want to do that as a PWM output, driving a s…

I have the machine built, so it is what it is atvthis point. I have a 4 relay board with opticouplers and a seperate 5v feed to the board for the relays. Im only using 3. One for the motor, fan power and leds (108 5050s). I have a seperate pin for fan speed on a pwm pin and the interlock is a end…

[image] scrapheapind: I planned on using Adafruits 16x2 LCD 5 button shield on an UNO R3. When you said this, in a section on project guidance, I thought you were starting off on the right foot. Left hoof, this is now. Okay. So it's built, but you need guidance. We'll need: schematic ph…

Hello scrapheapind Take a peace of paper, a pencil and design based on the IPO model a program structure plan before start coding. Identify functions and their depencies. Now start with coding and testing, function by function. At the end merge all tested function together to get the final sketch…

Thanks for the input. I did have everything sketched out in Excel, mapped and formulas needed. Spent some time looking up functions and states and figured it out. I suppose the lazy part of me was hoping for a pre-written code, but in the end, I did it myself and it works. Once the project is 10…
