ESP32 comes in the NodeMCU structure we are familiar with, but it also offers bluetooth support. Exciting for IOT applications, this ESP-WROOM-32 model features internal antenna, RF balun, power amplifier, low-noise amplifier, filters and power management unit. It features 2.4 GHz dual-mode Wi-Fi and TSMC 40nm low power technology Bluetooth chips.

Esp8266 is an affordable and breadboard-compatible development board that allows you to easily consume your projects based on ESP8266.

The HC-SR505 is a mini PIR (Passive Infrared) motion sensor module used to detect the movement of an object in front of it, as its owners have explained.

4Ω small speakers can be output directly, it has enough output power, energy and good sound quality.

NYAF cables are used in mobile installations and connecting devices. It can be used as a grounding cable, as well as for terminal connections in automatic controls, inside electrical panels and in different cable ducts in humid areas for various purposes.

The MAX7219 is integrated with 10MHz serial communication (SPI) used to use units such as common cathode LED panels, 7-segment displays, level states in microcontroller projects.

This module consists of an 8-bit microcontroller as the main control chip. It can be useful for projects where HC-SR04 ultrasonic module is used. It can calculate the distance of an object from the sensor and displays it on the mounted 3-digit LED display. In addition, it can also extract its data through the serial pins on the card.
