Hello all
I am kind of new (noob) with arduino programing and i whant to try an ambitious project.
The project:
I want to build a Whashing + Curing station for SLA 3D Prints.
Objectives:
To have an OLED display and a Rotary encoder to be used on a menu that has 2 options:
-> Washing (stepper rotates at 100rpm, UV light is OFF)
-> 5 min
-> 10 min
-> 15 min
-> Curing (stepper rotates at 10rpm, UV light is ON)
-> 5 min
-> 10 min
-> 15 min
Hardware
- Arduino Uno
- Oled SH1106 1.3" display
- Roraty encoder
- Relay (to turn on the UV Light)
- Stepper motor ( to turn the base )
- Buzzer to alert when time is up
- Switch on the door (to pause the timer when door is opened)
I have a small sketsh base on existing system tha boots up and has a counter, a button and a oled.
When you press the button the countdown starts (value is hardcoded to 15sec) and the relay is on.
It works for my intention but when i import the code for the stepper and run it, the display stays at 00:00 the relay turns on and the stepper turns on but it ignores the 15 sec timer (hard coded) and only stops after 30 sec and the when it stops, the display starts the countdown.
The code
#define name "Curing/Washing 1.0"
#define RelayPin 8 //Porta do Arduino que irá acionar o relé
#define RelayLevel LOW //Nivel lógico de ACIONAMENTO do relé
#define pinStartButton 7 //Porta do Arduino em que o botao Start esta ligado (o second terminal do botao deve ser ligado em GND)
#define ResetTime 2000 //define o time em que o botao Start deve ficar apertado para efetuar o reset (em miliseconds)
#define CounterValue 5 //define o time do counter (em seconds)

Is there anyone that can help me get this project of the groung ??
