Digital LCD Car Fridge Incubator Fish Tank Meter Gauge Thermometer with 1m cable

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.

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).

This is 125K RFID Tag. The RFID technology is used for sensing and identifying tagged people and objects for access control, automation, and a whole range of different applications.

Operating on a frequency of 125kHz, these tokens are all pre-programmed with unique ID numbers to communicate wirelessly with RFID Readers over distances of around 10cm or less. This means you can attach it to vehicles or items, keyrings or even pets’ collars to keep track of the location via an array of readers in the office, warehouse or home.

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.
