Control an RGB LED with a Button | Beginner Arduino Project

[@legend_guyes7638]

Guys i wrote the Code, Here // define pins #define BLUE 3 #define GREEN 5 #define RED 6 #define button 2 // define color mode int mode = 0; void setup() { // setup LED lights pinMode(RED, OUTPUT); pinMode(GREEN, OUTPUT); pinMode(BLUE, OUTPUT); //setup buttons pinMode(button, INPUT_PULLUP); } void loop() { if (digitalRead(button) == LOW) { mode = mode + 1; delay(400); } // off if (mode == 0) { analogWrite(BLUE, 0); analogWrite(GREEN, 0); analogWrite(RED, 0); } // White if (mode == 1) { analogWrite(BLUE, 225); analogWrite(GREEN, 225); analogWrite(RED, 225); } // Red if (mode == 2) { analogWrite(BLUE, 0); analogWrite(GREEN, 0); analogWrite(RED, 225); } // Orange if (mode == 3) { analogWrite(BLUE, 0); analogWrite(GREEN, 75); analogWrite(RED, 225); } // Yellow if (mode == 4) { analogWrite(BLUE, 0); analogWrite(GREEN, 220); analogWrite(RED, 225); } //Green if (mode == 5) { analogWrite(BLUE, 0); analogWrite(GREEN, 225); analogWrite(RED, 0); } //Blue if (mode == 6) { analogWrite(BLUE, 225); analogWrite(GREEN, 0); analogWrite(RED, 0); } // Violet if (mode == 7) { analogWrite(BLUE, 225); analogWrite(GREEN, 0); analogWrite(RED, 100); } // Switch off if (mode == 0) { mode = 0; } }

how nice of you,,,!! lovely

[@abusekak1934]

for anyone that cant really copy paste and want a simpler version, (im experienced with 4 years coding), here is a way simpler version written by me (its actually is more advanced and has way more colors but is easier to write) #define blue 3 #define green 5 #define red 6 int mode = 0; void setup() { pinMode(red, OUTPUT); pinMode(green, OUTPUT); pinMode(blue, OUTPUT); } void loop() { int bluevalue = random(1, 500); int redvalue = random(1, 500); int greenvalue = random(1, 500); analogWrite(blue, bluevalue); analogWrite(red, redvalue); analogWrite(green, greenvalue); delay(400); }

[@abusekak1934]

ok ye i forgot to remove the: *int mode = 0* but u can type it or skip it either way it will still work

[@matchesbattlefield8840]

This is great! clear and insightful. My only concern is that it overemphasises the placement of the button as something that is essential, when other placements can work, but that's only a minor gripe. Great video!

[@codymagasich8051]

For everybody here saying this code did not work for them. Check your RBG LED and ensure it is a common cathode and not a common anode. I had the same issue and when I installed the correct RGB LED it worked perfectly

[@BrosifStalin]

Then how do u make it work with a anode pin RGB LED

[@codymagasich8051]

@@BrosifStalin it’s a completely different circuit for a common anode. I’m not an expert on them but you could probably find circuit diagrams online to compare the two. I just purchased the common cathodes when I realized that was the problem

[@babalolamichael1123]

great job! but can you share your arduino code used for this project????

[@abusekak1934]

use mine *it has way more colors and is way more advanced. but simpler to write if u dont have copy paste* #define blue 3 #define green 5 #define red 6 void setup() { pinMode(red, OUTPUT); pinMode(green, OUTPUT); pinMode(blue, OUTPUT); } void loop() { int bluevalue = random(1, 500); int redvalue = random(1, 500); int greenvalue = random(1, 500); analogWrite(blue, bluevalue); analogWrite(red, redvalue); analogWrite(green, greenvalue); delay(400); }

[@MALGAPOVANRAILYR]

for all who wondering that this code is not working your wrong just debug the if (mode == 0) in the end of the code and replace the zero and input 8 if (mode == 8) and it works just watch and focus to the end of the vid 5:17

[@justb4lboa23]

This tutorial was very helpful for me! I wasn't really understanding arduino push button stuff and this helped me a lot! Thank you!

[@Bansheekilr]

This is exactly what I was looking for! Thanks 🙏

[@MrBobWareham]

I know you don't want to share your code, but it would help if you made the text on screen bigger, so we could follow along

[@zanejr.2946]

This tutorial really did merged with my ideas, liked it brother.👍😁

[@Prubotics]

Very clear and extremely useful at this point.

[@michaeldeloso9042]

How may I set the led to super slow changing colors such as 10 seconds delay transition colors of rgb and switch automatically to music reactive mode when there is playing music or songs on my videoke and turn back automatically to super slow changing colors of red green blue when there's no music playing or in standby mode?

[@FishFingers764]

u can do something like analogWrite(BLUE, 225); analogWrite(GREEN, 0); analogWrite(RED, 100); delay(10000); analogWrite(BLUE, 121); analogWrite(GREEN, 42); analogWrite(RED, 32); i think

Why can't we connect a single resistor to the cathode? I am going to do that...

[@EnderKnigh]

wait it keeps saying pinmode not defined or something like that?

[@emilianomartinez8036]

How can I make the LED take less time to change color?

[@arjunj7540]

you can do it by reducing the delay time in code

[@abusekak1934]

here is a simple version (works kind off the same): #define blue 3 #define green 5 #define red 6 int mode = 0; void setup() { pinMode(red, OUTPUT); pinMode(green, OUTPUT); pinMode(blue, OUTPUT); } void loop() { int bluevalue = random(1, 500); int redvalue = random(1, 500); int greenvalue = random(1, 500); analogWrite(blue, bluevalue); analogWrite(red, redvalue); analogWrite(green, greenvalue); delay(400); } //YES i wrote this

[@j0hnk120]

Hello, The biggest problem is that you put in #define red,green and blue instaed of RED,GREEN and BLUE (the capital letters make a differrence).Also you had little mistakes in your code like not using "," before color and stuff.Here is your code #define BLUE 3 #define GREEN 5 #define RED 6 #define button 2 int mode = 0; void setup() { pinMode(RED, OUTPUT); pinMode(GREEN, OUTPUT); pinMode(BLUE, OUTPUT); pinMode(button, INPUT_PULLUP); } void loop() { if (digitalRead(button) == LOW) { mode = mode + 1; delay(400); } if (mode == 0) { analogWrite(BLUE, 0); analogWrite(GREEN, 0); analogWrite(RED, 0); } // White if (mode == 1) { analogWrite(BLUE, 255); analogWrite(GREEN, 255); analogWrite(RED, 255); } // Red if (mode == 2) { analogWrite(BLUE, 0); analogWrite(GREEN, 0); analogWrite(RED, 255); } // Orange if (mode == 3) { analogWrite(BLUE, 0); analogWrite(GREEN, 75); analogWrite(RED, 255); } // Yellow if (mode == 4) { analogWrite(BLUE, 0); analogWrite(GREEN, 220); analogWrite(RED, 255); } // Green if (mode == 5) { analogWrite(BLUE, 0); analogWrite(GREEN, 255); analogWrite(RED, 0); } // Blue if (mode == 6) { analogWrite(BLUE, 255); analogWrite(GREEN, 0); analogWrite(RED, 0); } // Violet if (mode == 7) { analogWrite(BLUE, 255); analogWrite(GREEN, 0); analogWrite(RED, 100); } // Switch Off if (mode == 8) { mode = 0; } }

[@ohnobo14]

If you dont want the RGB cycling through colors and you want a geniune RGB pulse here is a code with 5 different options that works with the above setup: // define pins #define BLUE 3 #define GREEN 5 #define RED 6 #define button 2 // define color mode int mode = 0; // 0 = off, 1 = pulsing, 2 = reset to off // Variables for pulsing effect int pulseValue = 0; // Variable to control pulse intensity (0 to 255) int pulseDirection = 1; // 1 for fading in, -1 for fading out void setup() { // Set RGB LED pins as OUTPUT pinMode(RED, OUTPUT); pinMode(GREEN, OUTPUT); pinMode(BLUE, OUTPUT); // Setup button pin pinMode(button, INPUT_PULLUP); } void loop() { // Check if the button is pressed (LOW means pressed, as we use INPUT_PULLUP) if (digitalRead(button) == LOW) { // Wait a short time to debounce the button press delay(300); // Increment the mode (1st press: pulsing, 2nd press: reset to off) mode = mode + 1; // If mode reaches 3, reset to mode 0 (off) if (mode > 2) { mode = 0; } } // Mode 0: LEDs off if (mode == 0) { analogWrite(BLUE, 0); analogWrite(GREEN, 0); analogWrite(RED, 0); } // Mode 1: Fade in and out (pulsing effect) if (mode == 1) { if (pulseDirection == 1) { pulseValue += 5; // Increase brightness if (pulseValue >= 255) { pulseDirection = -1; // Change direction to fading out } } else { pulseValue -= 5; // Decrease brightness if (pulseValue = 255) { pulseDirection = -1; // Change direction to fading out } } else { pulseValue -= 5; // Decrease brightness if (pulseValue = 255) { pulseDirection = -1; // Change direction to fading out } } else { pulseValue -= 5; // Decrease brightness if (pulseValue = 255) { pulseDirection = -1; // Change direction to fading out } } else { pulseValue -= 5; // Decrease brightness if (pulseValue = 100) { pulseDirection = -1; // Change direction to fading out } } else { pulseValue -= 5; // Decrease brightness if (pulseValue

I have a problem tho... I need to program 2 rgb led lights and they are expected to function like traffic lights signals... can anybody send help?😅 I need rgb led 1 (red light) to light up together with rgb led 2 (green light)... thing is they should have different durations ... though they lighted up together, they should turn off on different time durations. The rgb led 1 should light up for 15 secs and the rgb 2 should light up for 12 secs. Please help

[@FishFingers764]

u can just use red and green led instead of rgbs and do something like #define red 3 #define green 4 void setup() { pinMode(red, OUTPUT); pinMode(green, OUTPUT); } void loop () { digitalWrite(green, LOW); digitalWrite(red, HIGH); delay(15000); digitalWrite(red,LOW); digitalWrite(green,HIGH); dealy(12000); }

[@chbonnici]

Thank you Very kind will try it.

[@chbonnici]

Please note that in the mode OFF if (mode == 1) this should be 0 not 1 . As 1 is for white. as shown underneath. //OFF if (mode == 0) { analogWrite(BLUE, 0); analogWrite(GREEN, 0); analogWrite(RED, 0); } all work fine after except the after the last colour it does not switch off and after another pulse it should go back to the first colour. Please can you check and let us know. Thank you beforehand.

[@chbonnici]

to solve the problem at the end add this and all works fine. //SWITCH OFF if (mode==8){ mode=0; } }

[@Sizzlik]

The longest leg on an RGB LED is NOT the Cathode..nor the Anode. Its the COM for common. As it can be either a common/shared Anode or a Cathode..that depends on the LED you bought..both available. And on everyday LED or other diodes or polarized capacitors, the longest is the Anode(+). Dont make tutorials, if you teach bullshite.
