I built a device where you enter a password: if it’s correct, everything is fine, but if it’s incorrect, a distinctive sound plays; if you enter the wrong password three times, a siren starts blaring and a light begins to flash. You can also connect a servo motor to the device, which rotates when the correct password is entered. And please, don’t judge too harshly—this is my first Arduino project. Thanks!
Hi! I started making a new Roblox Game. I will tell about it a bit later
Today I was filling out the README on GitHub. I wrote about the functionality and the components I used, outlined the wiring diagram for connecting the boards, listed the libraries, and covered installation and flashing. You can check out my project on GitHub—though I haven’t uploaded the code yet.
I’ve started a new project called SpotifyMe. The concept is simple: you connect to the device via Bluetooth and play music (it doesn’t have to be Spotify; any music app works). The screen displays the track’s album art, artist, and playback timeline, and you can skip tracks forward or backward using buttons. You can also adjust the volume by turning a rotary encoder, and pressing it allows you to play or pause the music. On the technical side, the build is based on an ESP32 and uses an ILI9341 display (manufactured by ILITEK in 2011), a KY-040 rotary encoder, a DS1307 RTC module (featuring an I2C interface and 56 bytes of NV SRAM), two buttons, an RGB LED for accent lighting, and three 220-ohm resistors.
README Git. I added everything to GitHub and wrote README
Hi everyone! This is my first post, and the project I’m working on is called the Space Habitat Monitor. This photo was generated by an AI as an example of what the final product will look like.
You could really call it anything, though, since the concept is quite simple. It’s an ESP32-based device that monitors metrics like temperature, humidity, pressure, and acceleration, and it also includes a built-in gyroscope. It has potential applications everywhere—for instance, on the ISS, where astronauts could use it to track vital environmental readings. If the readings drop below average levels, an LED indicator lights up. I tailored the system specifically for spacecraft, basing the specifications on NASA data, but anyone can download the source code from GitHub and customize the settings. And if you have a 3D printer, you can print a case for this device and place it inside for greater convenience and safety. Thanks for reading!
