Hey everyone, I'm in a bit of a bind with a project and could really use some help. I've got just one week left to program an LED setup using an ESP8266 for a gift to a mentor. I'm looking for something really basic—like, explain it to me like I'm five! I want the LED to cycle through different modes (On, White, Red, and possibly a red cycling effect) with just a button press.
I've been at this for a couple of weeks, starting with some 3D modeling for my gift, then running into issues with my ESP8266 board arriving without pins (which I had to solder in myself), and now I'm overwhelmed by the sheer volume of programming guides out there. Some use Arduino IDE, others suggest WLED, but I want to avoid anything that requires an app,
The Arduino IDE tutorials assume a lot of prior knowledge, and I'm not even sure if I need a breadboard to make this happen. Also, I've learned that using a USB C for power should work, but there's some debate about needing resistors for it. Any guidance on where to start programming this thing would be **greatly** appreciated!

Hey! So first off, you definitely don’t need to stress too much. If you're using an ESP8266 with WS2812B LEDs, just connect them to the board's GPIO pins directly and make sure to power them correctly. You can power the ESP8266 with a micro USB cable for ease.
For programming, I'd recommend grabbing the Arduino IDE. There are tons of example sketches available for controlling the LEDs. You might want to start with a simple ‘blink’ code to get comfortable with coding for the board—it’s literally just turning the LED on and off. Once you’ve got that down, you can easily expand it to switch colors based on button presses. For a button, you might check out using a pull-down resistor as it’s critical for stable readings. This way, as long as your setup is solid, you’ll have a blast with it! Good luck!
Awesome, thanks for breaking that down! I didn’t know about the pull-down resistor part—definitely adding that to my notes!
