Among various tutorials of Electronics Hub, this project aims to make a spy robot that can be sent to the remote areas and is designed to capture audio and video information. The robot can be controlled by the remote, which has four switches to direct it in four directions in a maximum controllable range of 125 meters. This type of remote Operated Spy Robot Applications can be used to keep a check on the behavior of wild animals where human beings cannot reach, in army applications to detect the bombs, in industries etc. There are some limitations in this project like the system does not work for longer distances and also it is actually a theoretical circuit, hence when it will be implemented practically, it may require some changes.
Raspberry Pi – Daily Deviations Picture Frame
This tutorial has made use of the raspberry pi to power a photo frame for the living room. The common digital picture frames found at home that cycles through a bunch of pre-loaded jpg of your friends and family has been reinvented by using Raspberry Pi Model B, 8GB SD Card, and Rapbian Wheezy.In this project, gifs and other files don’t work yet. With this, a slideshow begins using the frame buffer. The slideshow is halted in the midnight to reboot the Raspberry Pi and then cycle starts over. This process works after installation of Raspbian wheezy on the SD Card, popping it into the raspberry Pi and then booting it up. The root partition is expanded to fill SD Card and the keyboard layout is changed along with the time-zone.

This tutorial is based on an open source Arduino project for a Smart Cane that assists blind people to walk alone anywhere with the help of inputs provided through an obstacle sensor and giving feedback through haptics (vibration motor). The device is affordable and can be easily replicated in couple of hours. It automatically detects the obstacle while walking and provide feedback by letting the walking stick vibrate along with a warning sound. The equipment needed for this project are Arduino UNO, Ultrasonic sensor (HCSR04), Mini breadboard, 9 volt battery connector, DC male power jack, Buzzer, jumper wires, a broken cellphone for the vibration motor, a Toggle switch and other peripheral devices.
Raspberry Pi Internet of Things Demonstrator
Internet of things has the ability to assimilate small devices into much larger devices, once connected to the internet. This tutorial by Whaley geek demonstrates an easy method to connect hardware over the network by using two Raspberry Pi computers. As any small device is connected to the internet produces data which is already uploaded to the internet. This data provides an opportunity to being analyzed on large servers, which are accessible on mobile apps or to send messages to other internet connected devices. In this tutorial, two Raspberry Pi computers are used to monitor a switch and to control an LED, connected via a local area network.
DIY Ethernet based home security system
Among different types of security system available in the market, one of them is the SMS notification service which is affordable but not that reliable. The system might face congestion problem in SMS center during a theft. The effective but expensive one is the Internet or Ethernet Notification system, which is not only reliable while using TCP, but operative too. Internet services remain always in demand and it would be rare to face a sudden failure.Since the later system is costly as the embedded Ethernet devices are hard to deal with and include heavy expenditure, therefore one can build its own security system at home over the internet using an Ethernet device. The cost would be same as any microcontroller and it also offers better options for your home security in comparison to the one which is commercially available.
Building a DIY Robot-Controlled Arduino Robot

The robot receives its power from a battery box connected to the power input jack of Arduino board.
Internet-of-Things-Sous-Vide Cooker Project
Attention cuisine lovers, this project by Chuck Tung, is an embedded micro-controller project, named as “Internet-of-Things Sous-Vide Cooker”. Inspired by the book called “Modernist Cuisine”, acquainted him with sous-vide, which offers a high-end crock pot and every time cooks your food effortlessly with perfection, without fail. But the machine is costly and take hours to cook. So, Tung decided to build his own sous-vide machine and completely turned it into a smart, internet-connected device.The list of items required for this project includes Crock pot, solid-state relay to control power to the crock pot, Arduino using the PID library to control the solid state relay, waterproof DS18B20 to measure the water temperature, and so on.
DIY Home Automation Remote Control
Android Manager is an amusing interface for controlling Arduino remotely over Wi-Fi or Ethernet. Whether it is home automation or remote control, Arduino manager has already captured everybody’s attention. This post by James Bruce, following the trend, has explained the role of Arduino manager and how is it used to control Arduino from mobile or tablet. The Android manager has the ability to turn on or off relays and servos; it also helps in gathering sensor data and to create thresholds or alarms that react to the particular data. The android apps are identical in functioning with the lack of code generator. In this project, Mr. Bruce has tested it with iOSwith limited requirements.
DIY Simple Solar Circuits
Windell Oskay, in his blog has explained how to affix solar power to small electronics projects instead of using battery powered night lights, garden lights or decorations for Halloween and save money and nature. The device, here, used for accumulating solar device is small solar panel for all of these circuits. The direct drive to use power from a solar panel is to connect the load directly to the output leads of the solar panel.This type of basic “direct drive” circuits is comfortable with their design function, but doesn’t deliver any energy storage, and is at risk of blinking out when a bird or cloud passes overhead. They are perfect for running a small fan or pump but for powering a microcontroller or other computer, power interruption can be troublesome.
Build your own Arduino based sound sensitive LEDs
One of the most common usage of sound sensors is to turn lights off and on by clapping. Taking clue from the copiousness of this sensor, it can be used to hook up to a range of LED lights that plays with music, clapping or knocking. With all the necessary equipment, that connects the sound sensor and the LEDs, the Arduino can be programmed accordingly to make sound sensitive lights.You will need an Arduino with a breadboard and its cables, a sound sensor for detecting high sensitivity sound sensor module by Keyes, LED lights and resistors. The sound sensor has four pins which are connected to the Arduino and on the top of it, there is a little flathead screw to adjust the sensitivity as well as the analog output of the sound sensor. Start with one LED and start attaching resistor from ground to the shorter side of the LED.
