Hi! Can anyone help me with the coding? bool btnIsUp = true; // the button is not being pressed at the start bool lightIsOn = false; // the LEDs are OFF at the start // constant variables (won't change) const int ledPin1 = 3; // LED 1 attached to number 3 const int ledPin2 = 5; // LED 2 a…

I made my own wiring diagram. For the code, I found them on YouTube.

In a few sentences, please tell us exactly what you decided you want the components to do. When is the assignment expected to be ready ?

First, I want all the LEDs to turn ON when I press the button once, where the LEDs need to stay ON (the LEDs doesn’t go OFF when I release the button). Then, after I turn ON the LEDs for a few seconds, I want to make a light sweeping effect from LED Pin 1 to 5 where I also be able to adjust all the…

It’s breakfast here right now, I’ll return after eating. Other volunteers might step-up and help in the meantime. What time of day is it where you are ? Do you have the time over the next hour or two to learn things ?

that’s okay, take your time! and it’s 2 A.M now here. I try to learn or tweak my code before I go to sleep. I think I can stay for the next 30 mins to 1 hour. It should be done in the next 24 hours then.

We approach the assignment a bit differently, but I’ll give it a try!

Hi, Jim. I tried and added more pins to the code. It does turn ON and OFF the LEDs, but when the potentiometer is turned to the right (which decreases the LEDs’ brightness), the LEDs are a bit jittering/flickering. const byte btnPin = 2; const byte ledPin1 = 3; const byte ledPin2 = 5; const byte…

We always start with writing a preamble which you have done. Next we always make a preliminary schematic, see below, does this make sense to you ? You can use KiCAD or EasyEDA for drawing. [2025-08-16_10-19-36]

This is the same, right? Although it’s more confusing to look at.. [image]
