Pico: drive a 28BYJ-48 stepper motor with a ULN2003 driver
Wire a 28BYJ-48 stepper to a Raspberry Pi Pico with the ULN2003 board and drive it with MicroPython. Precise position control for about $3 in parts.
ESP32: PWM on every pin with the LEDC peripheral
Use the ESP32's LEDC hardware to generate PWM on any GPIO. The right way to dim LEDs, drive servos, and control motor speed.
ESP32: drive a hobby servo with LEDC
Wire a hobby servo to an ESP32 using the LEDC peripheral. The right way to control an SG90 or MG996R without the Servo.h library.
ESP32: drive a NEMA 17 stepper motor with the A4988 driver
Wire a NEMA 17 stepper motor to an ESP32 using the A4988 stepper driver. The right call for real torque and precise positioning.
ESP32: build a 2WD robot base with motor control
Two DC motors, an L298N motor driver, an ESP32, and ultrasonic distance sensors. The base you build a robot on top of.
Arduino: drive a 28BYJ-48 stepper motor with a ULN2003 driver
Wire a small stepper motor to an Arduino using the ULN2003 driver board. Precise position control without the expensive hardware.
Arduino: control a servo motor
Drive a hobby servo (SG90, MG996R) from an Arduino. The shortest path from Arduino to 'something moved.'
