Hello Everyone, In this project I’m going to show you how to make ESP32-CAM board surveillance Robotic car.

Componenets that I have used

1.ESP32-CAM board

2.Bread board

3. Jumper wires

4. 2 DC motors.

5. Motor driver module L298.

Apart from storage of data and sending alerts, the IoT can be used to build elaborate systems that work autonomously without human monitoring or intervention. This is possible through Machine to Machine ( M2M ) interactions, where different IoT devices communicate with each other either directly or indirectly, and carry out actions depending on the information/data they receive.

Types of IoT interactions

The Internet of Things (IoT) is a vast network of devices that share information using different Internet protocols. It is comprised of different kinds of interactions between devices, online servers, and humans. Most interactions involve communication…


This tutorial is a quick getting started guide for the ESP32-CAM board. I have used ESP32-CAM board for face detection and video recognization using simple example code is given in arduino esp32 library.

it also features a microSD card slot that can be useful to store images taken with the camera or to store files to serve to clients.

The ESP32-CAM doesn’t come with a USB connector, so you need an FTDI programmer to upload code.

Next You need to add on ESP32 in your Arduino IDE.


A Atmel ATiniy85 microcontroller is an 8-pin IC available in both surface-mount and through-hole DIL packages. The device is designed with minimum of external componets.

ATinity 85 has three diifferent types of memory:

1. 8kb flash memory wich will be store programm instructions.

2. 256 bytes of SRAM. which is used to contain the data while the execution of instruction.

3. 512 bytes of EEPROM that is used to store nonvolatile data that needs to be retained after a loss of power


Now days wifi password hacking is very usual to do. So here I will show you how to make wifi jammer which means how to block the wifi signal. here I have used Nodemcu or ESP8266 board for blocking the wifi signal and also able to create fake wifi SSID, where the board is mostly famous for creating IOT applications. If you want to do more IOT projects with hands full of dirty check out my website or my YouTube channel

Disclaimer: It is illegal to use jammer in the public areas without taking permission of govt. authority. This…
