The Ethernet module for Arduino and compatible boards based on the Wiznet W5500 chip, faster than the previous W5100. It provides an easy way to connect your module to the local network and internet based WIZNET with a TCP/IP interface. Compatible with libraries with the same Ethernet API. A web server can be built with this UNO board shield. It can be used as a server or as a client.

ProtoShield Prototype Expansion Board with Mini Breadboard 170 points for Arduino UNO V5.0 features:
- To mount your projects in a comfortable and orderly way, access to all the pins of Arduino Uno R3, it has a universal plate and protoboard zone, 5V and Gnd buses, reset pushbutton, pushbutton and 2 general purpose leds, zones for integrated Soic and Dip
- The seamless mini breadboard has 170 connection points.
- You can stick on the shield with its self-adhesive back.

It can be used to control the microprocessor of the Arduino AVR PIC system and others, or as a digital potentiometer rotating the rotary encoder can be counted in positive and negative, depending on the direction of rotation; with the button of the rotary encoder can be reset to its initial state, which starts counting from 0.

XM-15B Bluetooth Serial Port Module Master Slave Compatible Arduino HC-05/06 features:

- Built-in hardware protector, never hangs

The module has two outputs: analog A0 and digital D0
Digital output D0 - signal 0 appears or 1 depending on the threshold setting
The threshold is set with the potentiometer
The sensor can be used for example:
Automatic watering for potted plants
With this module you will be able to measure the humidity of the soil, so that you will be able to control the humidity level of the soil of your plants
Characteristic:
Operation: 3.3V -5V
- Sensitivity adjustable by potentiometer
- Dual output mode: analog and digital
- Red LED - power indicator
- Green LED - indicator digital switching output
- PCB measurements: 3 x 1.5 cm
- Probe measurements: 6 x 3 cm

It is made up of a 16-character, 2-row, 6-button display.
The display is compatible with the HD44780 controller and is connected in 4-bit mode so it can be used directly through the Arduino LiquidCrystal library.
