A 3.5-inch ST7796 Screen on the ESP32-P4
Wiring a 320x480 ST7796 SPI panel and its FT6336U touch controller to the ESP32-P4, plus the numbers from the first working build.
ESP32 + RGBNW Light + Motor Controller with Four Encoder Dials
Four EC11 dials and four OLEDs on one TCA9548A, driving a 24V RGBNW strip and a stepper motor, with a WiFi page that stays in sync with the dials.
ESP32 + A4988 24V Stepper Motor Control
I turned the three HSV color channels into generic Rails and hung an A4988 and a 24V stepper motor off Rail 1, with the encoders and the web page still responsive while it moves.
ESP32 + Multi-OLED + Encoder HSV Control System
Three OLED + encoder modules on one I2C bus through a TCA9548A, two-way synced with a WiFi web page, the HSV tests.
ESP32 + WiFi LED Brightness Control
A web page served by the ESP32 itself drives the onboard LED over 8-bit PWM, so anything on the local network can set the brightness.
ESP32 + EC11 Encoder + OLED Angle Feedback
Dual EC11 encoders with OLED display and WiFi WebSocket real-time angle feedback.
ESP32 + EC11 Encoder + Stepper Motor Control
Embedded motion control with EC11 encoders, DM430 stepper driver, and WiFi WebSocket dashboard.
ESP32 + RGBWW FCOB LED Communication
NeoPixelBus communication test with RGBWW FCOB LED strip: channel cycling and protocol verification.
ESP32 + INMP441 Noise Monitor
Real-time noise monitoring with INMP441 I2S mic, FFT analysis and web dashboard.
ESP32 + RGBWW FCOB LED Color Wheel Control
WiFi-controlled RGBWW LED strip with web color wheel picker and RGB-to-RGBW conversion.
Tinkercad 3-Channel LED Strip Control
Virtual 3-channel LED strip controller with push-button channel selection and potentiometer RGB control.
ESP32 + Serial Output Test
ESP32 microcontroller verification: uploading a sketch and confirming serial communication over USB.
