What is OBD2? OBD or On Board Diagnostics is a vehicles built in diagnostic system. Have you ever notices a check engine light blinking on the dash board of your car? That is your car telling you that some thing is not right and you should visit a mechanic before it is too late. [AdSense-C]When…
In the last post, I showed you how I made my long lasting heavy load power source for Raspberry Pi. Now let us take one more step forward. Let us build a mini computer with a 7 inch LCD Display, a small Keyboard and Mouse . Things Needed Raspberry Pi Lithium Polymer Battery > 12…
Raspberry Pi is simple, handy and cheap yet powerful single board computers of all time. It has USB ports to connect hardware such as pen drive, keyboard, mouse, HDMI port for display out, 3.5 mm port for audio and several GPIO pins to work with embedded projects, all of which can be powered using a…
Suppose we have two systems A and B and they want to communicate with each other, the data has to travel from A to B and vice versa. To ensure that this data reaches the receiver from the source, we need to have some rules that guides the communication. These rules are called protocols.[AdSense-C] These…
A network is a group of devices connected together for the sharing of data and devices. Using network people can communicate with each other across the world at very low cost using services like chat and email. Network can be used to transfer files and information between devices at a very high speed. A single…
As I mentioned in the previous posts, Node MCU is a tiny little board is based on the ESP8266 WiFi module which is specifically designed for working with or without microcontrollers which are specifically designed for IOT projects. Today I will how you how you can live stream and process Android Mobile Phone’s Sensor Data…
In my previous post, I mentioned everything about various types of WiFi antenna and how to position them. Now I will show you how to make a long range WiFi antenna using cheap WiFi Adapter and Scrap Parabolic Dish Antenna. Before going further, let us take a closer look at Dish Antenna and its working….
Arduino now allows you to create and upload code without even downloading Arduino IDE. Arduino Online Editor is a very handy but lesser-known service of Arduino which can compile and upload code to any of your Arduino board connected to your computer using just your web browser. Getting Started Create an Account The first thing…
Along with Arduino MKR GSM 1400, Arduino has released another board specifically designed for IOT, extending wireless connectivity using LORA Technology. MKR WAN 1300 is a small, yet powerful board combining the MKR Zero and LORA Technology in a single piece of hardware. LORA WAN is an emerging Wireless Networking Technology, which is designed for…
Arduino has now released a new board, supporting wireless connectivity using GSM network, widening the scope for IOT development for hobbyists and people who do not have much experience in the field of networking. Evolution of Arduino has always been a miracle to all competitors around the world. The development and support of Arduino community…
Mindflex is actually a game from Mattel which uses our brain frequency to move a ball through obstacles. The brain waves (EEG Signals) are captured using electrodes that are placed in the headband and these waves are processed to get the attention and meditation level, which is later fed to the base station via Bluetooth…
It is very clear that EEG sensors and headsets are becoming more commercialized and thus accessible to users for building custom brain-machine interfaces with various functionalities from switching TV channels to controlling wheelchairs as in this case. We decided to take it one step further. Here we will show you how we created a Mind-Controlled…
