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… 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 →
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 →
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 →
Plants Monitor – Arduino Soil Moisture Sensor
You can download our e-book ‘Learn Arduino’ from this link Do you have a plant in the living room which you often forget to water? I know, I know you often forget about it. So before it becomes yellow and dries more than the Sahhara, follow this tutorial and build a little soil monitoring project. The Plants Monitor will help you remember to water your little plant by flashing an… Read Article →
