A Smart Night Lamp for Kids

You can download our e-book ‘Learn Arduino from Scratch’ from this link 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… Read Article →

Solar Power your Arduino

You can download our e-book ‘Learn Arduino’ from this link 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… Read Article →

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

You can download our e-book ‘Learn Arduino’ from this link 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… Read Article →

LightBlue Bean – Zero Wires

You can download our e-book ‘Learn Arduino’ from this link 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… Read Article →

Transceiver 433mhz

Arduino 433Mhz RF Wireless Data Transfer

You can download our e-book ‘Learn Arduino’ from this link 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… Read Article →

Arduino Ultrasonic Range Finder – HC-SR04

You can download our e-book ‘Learn Arduino’ from this link 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… Read Article →




Digispark

Introduction to Digispark

You can download our e-book ‘Learn Arduino’ from this link 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… Read Article →

Arduino Beginner’s Course Lesson 3– Using the Serial Library

You can download our e-book ‘Learn Arduino’ from this link The Serial library is one of the most widely used library in Arduino development. The serial communication provides a simple communication interface to the PC or any other device that accepts connections over serial protocol. Throughout this course and some of the projects we post, Serial will be used to output either debug data or factual data. Debug data is… Read Article →

Arduino Beginner’s Course Lesson 2– Introduction to Arduino part 2

You can download our e-book ‘Learn Arduino’ from this link In this lesson we will go through the Arduino language. We’ll cover programming basics and introduce some of the libraries provided by Arduino. The Arduino Language is very similar to C. It’s almost the same language but Arduino provides us with several libraries to make things a bit easier. If you have absolutely no knowledge of any programming language I… Read Article →
