The ESP8266 – A Tutorial – Part 1 Environment Setup

Introduction The Internet of Things is a relatively new concept in the world of electronics. It was also quite expensive and maybe even unreachable by some hobbyists. The introduction of the ESP8266 changed that perception forever. Being first designed as a simple Serial WiFi adapter; today it is the most common IoT device among electronic hobbyists and hackers alike. The ESP is cheap, small, powerful and easy to program as… Read Article →

Arduino Bluetooth Tutorial HC-05

Bluetooth has been around for quite a while now. Being a common way to communicate with mobile phones, it was only natural to include this protocol in the Arduino arena. Bluetooth is typically a low power, medium range device, in fact it can reach up to 10 meters. Bluetooth operates on the same frequencies as WiFi, 2.4Ghz.Connections are normally one to one meaning no group communication is allowed by the… Read Article →

Smart lamp

A Smart Night Lamp for Kids

Order your Smart Night Lamp for Kids DIY Kit here!! Few weeks ago I heard my nephew (aged 7) complaining of the dark at night. Basically he was afraid So I decided to put knowledge into practice and build a night lamp for kids. Since the project was intended for kids, I thought of making the lamp change color every now and then. It should also be sensitive to light so… Read Article →




solar panel

Solar Power your Arduino

Solar panels or solar cells are becoming extremely popular as an alternative source of energy to power an Arduino. There are the 2 major setups which serve different purposes. First, the Arduino board can be powered directly from a solar panel or a set of solar panels. Secondly, and the more robust approach is to install a battery pack along with the solar panels. The batteries are charged by the… Read Article →

Arduino Beginner’s Course Lesson 6– Reading Sensor Data – Temperature TMP36

During this lesson, we will go through the process of reading sensor data, the TMP36 temperature sensor to be precise. First lets describe the sensor in  more detail. The TMP36 (ebay) has a linear voltage to temperature output meaning there is no error correction to be calculated from our end, the sensor handles it brilliantly on its own. The following are some details taken directly from the datasheet: Size: TO-92… Read Article →

LightBlue Bean – Zero Wires

Can you think of a device, which has a builtin 3v CR2032 battery, very small and portable, can run for over a month on a single battery and has a builtin BLE (Bluetooth Low Energy) device? No? We have!! The LightBlue Bean has all the features mentioned above and more… much more. First of all, this tiny device can be programmed wirelessly. Come again… 😮 Yes, no wires needed to… Read Article →




Transceiver 433mhz

Arduino 433Mhz RF Wireless Data Transfer

The most practical and cool way of sharing data from 1 Arduino to another is by far using a radio transmitter and receiver. The simplest form of wireless transmission (I could find) is the 433Mhz ASK modules. They come in pairs, a receiver and a transmitter. They are ridiculously cheap, selling at $1 or less a pair!! These modules provide simplex 1 way data transmission, in order to get a… Read Article →

hc-sr04 ultrasonic range finder

Arduino Ultrasonic Range Finder – HC-SR04

In this tutorial we present a method of measuring the distance between an Arduino and nearby objects. It is of particular use for automated robots for giving them ‘eyes’ to look out for nearby objects, measure the distances between them, and acting upon that distance. We present the HC-SR04 range finder sensor The cheap sensors normally have 2 cylindrical objects resembling a speaker with pins in the middle. Well, one… Read Article →

Digispark

Introduction to Digispark

In today’s blog post we’ll analyze one of the smallest and most practical boards out there. The Digispark board. It’s size, including the USB port, is 25mm x 18mm (so tiny)!! This little board is powered by an ATTINY85 chip and clocked to 16.5Mhz. For conveniece, it has a built in USB port and can be plugged into a your computer without cables or adapters. Now that’s pretty awesome! It… Read Article →

Arduino Beginner’s Course Lesson 5– Installing and Using Libraries

Libraries are an essential part in the Arduino world. They are what makes Arduino so easy to use. Libraries are written to encapsulate complex functions and expose them as simple function calls to the user. For example to switch a pixel on and off in an LED monitor. This is relatively very complex but, fortunately some folks at Adafruit created a library that enables us to handle an LEd monitor… Read Article →
