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 →
