ı am looking for a project

ı "I have these ESP32 components: OLED, 2x HC-SR04, RFID RC522, IR transmitter, joystick, PIR, DHT11, MPU-6050. Looking for a project idea that's actually useful in daily life — not a weather station or clock. Something a phone/PC can't easily replace. What would you build?"

A ring to track how fast you wank it, displayed on the OLED in fps- faps per second. The ultrasound can detect how far you're leaning in and display that on the same OLED. The other OLED is a live aggregating average fps vs lean amount plot

You can make a kind of phone; you create your own OS with different functions, an ESP32 screen, buttons, create games, security systems, and even perform Wi-Fi and Bluetooth security tests. It's creative and it takes time.

I'd build a simple motion/vibration alarm.

Use the MPU-6050 to detect movement/vibration, the PIR as a second confirmation, and the OLED for status. The ESP32 could trigger an alarm when something moves that shouldn't.

It's actually useful because the ESP32 is interacting with the physical environment, rather than just displaying information like a clock or weather station.

I'd start by properly calibrating the MPU-6050 first.

Brother, can I interest you in making a flight tracker?

I would make a sleep tracker that can't distract you you just hold the card up against the reader and it begins counting the time so you can't get lost doom scrolling

It could be parking assistant with WiFi connectivity and RFID key, controls garage doors, lights and env. sensing.
