IR based Wireless Audio Transmitter and Receiver Circuit AUDIO By Aswinth Raj   Sep 26, 2018 0 IR based Audio Transmitter and Receiver Circuit Infrared  is the most commonly used wireless data transfer medium for limited range, and we already covered about  simple IR Transmitter and Receiver circuit . Today in this Article, we will learn how to build a Crude  Wireless Audio Transfer Circuit Using IR LEDs . Using this circuit you should be able to play songs from your IPod, mobile or computer to an external speaker without having to connect them directly though an AUX cable. The circuit comes with many limitations and there are better ways like Bluetooth to play songs wirelessly, hence this article only aims to help you understand simple  audio circuits  and at the same time have fun building it. Also the circuit of this project is simplified as much as possible to keep things simple and reliable to make the build easier, so this should be a great weekend proje

Bluetooth or WiFi – Which is Best for Your New Wireless Product? ELECTRONICS 0 Bluetooth or WiFi – Which is Best for Your New Wireless Product? There are numerous wireless standards at your disposal when creating a new product. Each choice has its own set of advantages and disadvantages. It really depends on your goal. In this article we’re going to look at the three  most popular short-range wireless standards  including:  Bluetooth Classic ,  Bluetooth Low-Energy  ( BLE ), and  WiFi Direct . The Need for Speed If high-speed data transmission is the most critical requirement for your product then most likely WiFi Direct will be the best choice. Everyone has heard of WiFi, but few know of WiFi Direct. Although that is changing. Standard WiFi requires an access point. So if you want to transfer data from one device to another it must pass through the access point. WiFi Direct has the speed advantages of WiFi without the need for an access point. Data can

10 Most Common Mistakes while using Arduino By Odunlade Emmanuel   Oct 26, 2018 0 10 Most Common Mistakes while using Arduino Starting out as a beginner with the Arduino, can be quite challenging for people without electronics background, you’d come across errors, some of which may have simple solutions but might take you days to solve. So to make things a little bit easier, I have created a list of  10 most popular Arduino errors  along with possible solutions to them. 1. Arduino Board not Recognized This refers to a situation where an Arduino board, connected to a computer is not recognized by the computer. When this happens, the board is usually not listed under the port lists of the Arduino IDE and is sometimes labeled USB2.0 under the device manager.  This happens when you use certain cheap Arduino clones which use the CH340g USB to Serial converter chip instead of the FTDI (FT232RL) and others used by the standard Arduino boards. The drivers for

Digital Compass using Arduino and HMC5883L Magnetometer 0 Digital Compass using Arduino and HMC5883L Magnetometer Human brain is built of complex layer of structures which helps us to be a dominant species on earth. For example the entorhinal cortex in your brain can give you sense of direction helping you to navigate easily through places that you are not familiar with. But unlike us, Robots and unmanned Ariel vehicles need something to get this sense of direction so they could manoeuvre autonomously in new terrains and landscapes. Different  robots  use different types of sensors to accomplish this, but the commonly used one is a magnetometer, which could inform the robot in which geo-graphic direction it is currently facing at. This will not only help the robot to sense direction but also to take turns in a pre-defined direction and angel. Since the sensor could indicate the geo-graphic North, South, East and West, we humans could also use it at times
