Can someone please help me code my project. I am trying to turn a light on and off at specific times. I know how to do this using the time.h and timealarm.h libraries. What I cant figure out is how to set the alarms and time with a grove joystick.
Post your code, and we'll help you with it.
I don't have anything yet. this will be part of a bigger project for controlling the environment for a bearded dragon. I'm having a hard time figuring out what libraries to use.
Sorry, I don't do life-support systems.
This is the easy way to do it. but I would like to be able to change time and alarms using a joystick.
#include <Time.h>
#include <TimeAlarms.h>
#define RELAY_PIN 12
void setup()
{
setTime(16,30,0,1,23,16); // set time hh/mm/ss MM/DD/YY
// create the alarms
Alarm.alarmRepeat(7,00,00, MorningAlarm); // 7:00am every day
Alarm.alarmRepeat(21,00,00,EveningAlarm); // 9:00pm every day
pinMode(RELAY_PIN, OUTPUT);
}
void loop(){
}
// functions to be called when an alarm triggers:
void MorningAlarm(){
digitalWrite(RELAY_PIN, HIGH);
}
void EveningAlarm(){
digitalWrite(RELAY_PIN, LOW);
}
So, tell us about your idea for a joystick user interface.
I was thinking hold joystick button down to enter menu. menu will contain: set time, set alarm 1, and set alarm 2. pressing the joystick will act as a select button and the direction controls would be used to navigate and change times.
Why not just use a rotary encoder? Couple bucks and are insanely easy to implement with the right library (don't even need interrupts if that's your thing).
After warily googling bearded dragon, and finding nothing obscene or scary, I see now why you won't use a rotary encoder. It's claws wouldn't be able to operate it. I'm still curious how it would be able to handle a joystick though.
I bought a grove kit that came with a joystick. I assumed it should be easy to use but I have no idea where to start.
The joystick is just meant to adjust the time and clock. A lot of people use buttons but I am using grove components and was trying to use what I got in my kit.
Is this what you have?
It only have X and Y axes are two ~10k potentiometers which control 2D movement .

No joystick button.
yes that's what I have. The joystick and be pressed in and it gives a different value.
Here are the values I get with the joystick.
center: x = 501
y = 509
left: x = 501
y = 270
right: x = 501
y = 743
up: x = 267
y = 509
down: x = 750
y = 509
pressed: x = 1023
y = 509
There is a 5 pins joystick button that have button, but you have only 4 pins type, so no button.

When you press the joystick in 2D movement, it gives a different value on the x & y potentiometers.
Here are some menu code not tested.
// Button defination for Keypad shield
#define btnRIGHT 0 // Okay
#define btnUP 1 // inc
#define btnDOWN 2 // dec
#define btnLEFT 3 // Select
#define btnSELECT 4 // Menu

Thank you. I will try out your code in the morning. I'm feeling sick right now.
tried your code but there were a lot of errors. I also found your code this derived from so I am going to try to compare them and see if I can figure out how to make it work.
would it be easier to get rid of the joystick and just use buttons. I want the user to be able to set the time (date doesn't matter), and what times to turn a light on and off.
Considering I have never seen an alarm clock with a joystick, then yes, buttons would be way easier.
Or at this point, you could have saved some time and energy and gone and bought a $3 alarm clock. Why reinvent the wheel?
the alarm is part of a bigger project. I am making a device that will turn lights on and off at specific times and monitor temp, humidity and uv of a terrarium.
