SG90 Servo Angle Control with Pot

Servo Motor (SG90) Control with Potentiometer The main objective of this project is to precisely control the angular position of a servo motor in real time using an analog input unit, the potentiometer. The project is a basic engineering example to grasp the logic of analog-to-digital conversion (ADC) and signal mapping. Operation Logic: Analog Data Reading: When the user turns the potentiometer, the resistance change results in a voltage signal between 0V and 5V on the A0 analog pin of the Ard

ESP32 LED Brightness Control with a Potentiometer (Analog → PWM)

In this project, we control the brightness of an LED analogically using a potentiometer. The ESP32's ADC pin reads the 0-3.3V voltage from the potentiometer, and this value is then converted into a PWM (Pulse Width Modulation) signal and sent to the LED. As a result, as you turn the potentiometer, the LED gradually brightens and dims. With Arduino Core 3.0+, `analogWrite()` can be used directly; on the ESP32-S2/S3, the ADC resolution is fixed at 12-bit.

ESP32 Servo Motor (Potentiometer Control)

In this project, we control an SG90 servo motor using a potentiometer. We adjust the servo angle by mapping the analog value read from the potentiometer to the 0–180-degree range. Thanks to the ESP32Servo library, any GPIO pin on the ESP32 can generate a PWM signal. This is a fundamental control method for robotic arms, camera gimbals, and automatic door mechanisms.

ESP32 Color Mixer Light (3 Potentiometers + RGB LED + OLED)

A smart color-mixing lamp that lets you mix any color you want by turning three potentiometers with the ESP32! As you turn the red, green, and blue potentiometers, the common-cathode RGB LED changes color in real time. The SSD1306 OLED display shows real-time values for each color in the 0–255 range, visual fill bars, and the HEX web color code (such as #FF8040). A mini professional color studio—teaches RGB color theory, ADC analog reading, brightness control via PWM, and I2C display design all
