The resin paste for welding 150g Yaxun YX-20

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.

5mm 5537 LDR is a 5mm light-dependent resistor with a “5537” model number, which is a photosensitive component that changes its electrical resistance based on the intensity of ambient light. Its resistance is high in darkness and decreases as light increases, making it useful for light-sensitive applications like automatic lighting systems, alarms, and light-level detection.

Arduino Nano has enough processing power to control many electronic components. It has several I/O pins, which allows to connect it to many components. , it is a compact and reduced version of Arduino uno maroc.

Arduino Nano has 14 digital inputs/types (6 of which can be used as PWM outputs), 8 analog inputs.

The MQ2 analog gas sensor is used in gas leak detection equipment. This sensor is suitable for detecting LPG, butane, propane, methane, alcohol, hydrogen, and smoke. It has high sensitivity and a fast response time; the sensitivity can be adjusted using a potentiometer.

MODULE compatible Arduino to control 4 motors DC or 2 stepper motors and have 2 connections for servomotors. This shield uses pins D3 to D12 for operation (direction, speed, etc).

The module is based on two L293D drivers and can control up to 4 DC motors with an intensity of 0.6 A per output (1.2 A at peak).

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.
