Stepper motor 28BY J-48 with Driver ULN2003
the ULN2003 stepper motor driver or in English stepper motor, unipolar (4 phases/ 5 wires ) allows you to easily plug the small motor 28BY J-48 5v gràce to the 5 pin male connector and connects easily to an arduino or other through a 4 pin connector for control signals and Gnd (ground/-). The power supply of ULN2003 is between 5 and 12V.
The TL-Smoother is a module that can be added to stepper motor drivers (A4988, DRV8825, etc.) that are utilized in 3D printers and CNC.
Its role is to reduce vibrations, ripples and mechanical noise generated by stepper motors, smoothing the electrical signal transmitted to the motor coils.
This module improves print quality, reduces ghosting/moiré phenomena on printed parts and extends the mechanical life of motors.
12mm 12528 LDR is a type of photoresistor with a 12mm diameter and the model number GL12528, which changes its resistance based on the intensity of light it is exposed to. The resistance of the component is high in the dark and drops significantly as light increases, making it useful for detecting ambient light levels
This is a general OLED display Module, 0.91inch diagonal, 128×32 pixels, with embedded controller, communicating via I2C interface.

A 5v relay is an automatic switch that is commonly used in an automatic control circuit and to control a high-current using a low-current signal. The input voltage of the relay signal ranges from 0 to 5V.
Shaft support diameter 16 mm – SK16
The shaft can be tightened with an M5 screw provided.
The HW-201 IR infrared obstacle detection module can detect obstacles within a distance range of 2 cm to 30 cm, with a detection angle of 35 degrees.
It can operate with a supply voltage of 3.3 V to 5 V and has a maximum current consumption of 100 mA. The module outputs a digital signal, high when an obstacle is detected, low when no obstacle is detected.
The infrared LED has a wavelength of 940 nm and an operating frequency of 38 kHz. The module operates at temperatures between -25 °C and +55 °C.
