Hello,
I have this project with a relay. My kitchen lamp has 4 light bulbs but I just have one ON/OFF switch to control all 4's.
I want to use an Arduino to code and close the relays output according to on how I use the switch (in time).
-
A series of incremental relay activated: SWITCH PRESSED OFF-ON all 4 lamps at first (4 relays closed), SWITCH PRESSED OFF-ON 1 lamp, SWITCH PRESSED OFF-ON 2 lamps, SWITCH PRESSED OFF-ON 3 lamp, SWITCH PRESSED OFF-ON 4 lamp.
-
Activating the switch quickly OFF-ON-OFF-ON could go directly to the 1 lamp relay setting OR all 4 lamps relay setting.
I made tests with a MOMENTARY PUSH BUTTON (this is not the usual house light switch).
I found this project and modified it to add a function to turn the lights.
However, this project is only a template with 2 LEDS. I need to work with 4 LEDS and a different switch.
My question is:
Does anybody have a suggestion on how I could emulate the OFF-ON trigger action with a Push Button on a Breadboard and how to translate that into programming?
Here is what I have so far. Please bare with me I have no programming background:

/*Using a Single Button, create mutliple options based on how long the button is pressed
The circuit:
LED attached from pin 13 to ground through a 220 ohm resistor
LED attached from pin 12 to ground through a 220 ohm resistor
one side of momentary pushbutton attached to pin 2
other side of momentary pushbutton attached to Ground
Note 1: on most Arduinos there is already an LED on the board
attached to pin 13.Note 2: In this circuit, when the button is pressed, Ground Voltage is what will be applied.
