Building DIY Arduino, Pi Watch : Discussion of Options

It is not very difficult for a newbie to build a DIY Arduino wrist watch. Just our Arduino Clock project and altering components with ATtiny 13 or ATtiny 10 does the job. You just need to build a prototype with all components (not modules), design the circuit to test. Rest is ordering PCB fabrication and assembling service - hardly $15 service. If components cost $30, then cost with battery is … [Read more...]

Flexible PCB : DIY Method For Pro Grade Circuits

Adding Flexible PCB to Fabricated PCB Will Give Professional Result. We tested many methods - from ething various copper tapes, thin copper sheets to DuPont's Pyralux flexible circuit material. We will suggest to go with DuPont's Pyralux flexible circuit material or similar product. Here is Detailed Guide on Flexible PCB - DIY Method For Pro Grade Circuits. Of course, we have to follow designing … [Read more...]

1602A LCD Display I2C Serial Interface (Arduino)

Previously, we shown how to setup 1602A LCD Display with Arduino. The units of 1602A LCD I received, is really of good quality. You noticed in that guide we had use huge number of wires occupying many pins of Arduino. That is not good, specially for when Arduino running with ATtiny - if one display occupies so many pins then many projects becomes difficult to make real. We can use a module/IC for … [Read more...]

How to Write Arduino Library of Your Own

Normally, we write sketch on Arduino IDE, which essentially uses libraries. Library of Arduino is Set of Instructions to Avoid Repeated Huge Coding. As we discussed in how to learn Arduino programming, C++, C are important languages are important to learn for Arduino and embedded systems. Libraries add an abstraction from reality - which is practical for using things like a temperature humidity … [Read more...]

Resources For Learning Electronics in Official Arduino Website

Arduino, WordPress, Debian apt repository, OS X Homebrew - all appears just easy from front end. Free Software culture tries to give Freedom to users in the way Richard Stallman described. Like Any F/OSS Project, Arduino Also Not Newbie Friendly to Find Resources. The reason of unorganized structure of documentations is for a basic fact - none actually make huge money from any F/OSS project. There … [Read more...]

What is TTL? – Transistor-Transistor Logic

In our some previous articles, in context of Arduino for beginners, we discussed about serial connection, UART, SPI, I2C protocol. Another commonly heard phrase is TTL. What is TTL? Transistor-Transistor Logic or TTL is a family of logic circuits used in electronics invented in the 1960s. We will try to keep the article as brief and easy as possible. What is TTL? TTL is a … [Read more...]

IBM Continues Mainframe Making Them Smaller in Scale

The New Models From IBM Can Fit into 19-inch Racks Efficient For Building New Generation Cloud Infrastructure. IBM has unveiled two new models from its current z14 mainframe line, released last year. IBM Continues Mainframe Making Them Smaller in Scale Like We Predicted Before. The most striking feature of these new is their small size. These compact models z14 ZR1 and LinuxONE Rockhopper II were … [Read more...]

Arduino Audio Spectrum Analyzer : Basics on FFT and I²S

Actually building Arduino Audio Spectrum Analyzer Better Than What We Did Before in Our Project Arduino Simple Music Analyzer VU Meter From Stereo Input Demands Slight Higher Knowledge. For Building Better Audio Spectrum Analyzer, We Need Some Theoretical Idea Around FFT, I²S, FFT Library and Know How I²S Hardware Works. Better in the sense - not just 3-5 channel spectrum analyzer with 5-8 LED for … [Read more...]
