With Decreasing Production Costs, Hot Glue Gun Becoming More Common. Although, $3 hot glue gun easily available on various places - from Ebay, Amazon to local shops, there is reason to look at the 10 times costlier options. Also there is need of knowing technical matters about hot glue gun and it's cartridge - glue sticks. With advent of Arduino like prototyping boards, robotics and IoT works … [Read more...]
How to Read Ceramic Capacitor Values?
Reading Values Printed on Electrolytic Capacitors is Easy, Digits on Ceramic Capacitors Need to Know Some Theory. Like resistors has some coding which needs to decipher, printed digits on ceramic capacitors also needs deciphering. Here is How to Read Ceramic Capacitor Values. Values are normally printed on capacitors in Micro Farad (uF) with voltage. 10^6 (10 to the power 6) Pico Farad (pf) is … [Read more...]
Blink LED With 555 IC (Classic IC Circuit Diagram I)
This is Our First Tutorial From Classic IC Circuit Diagram Series. In our previously published article, we listed commonly used IC. There are some worldwide popular circuits with IC and our target is publishing some of them to Help the Arduino users to understand electronics in-depth. Blink is popular initial program in Arduino. Like Arduino, You Can Blink LED With 555 IC. In old days, instead of … [Read more...]
Basic Arduino Oscilloscope (on Serial Plotter)
In previously published articles we discussed about oscilloscope and also kit to build oscilloscope. Logic analyzer is another tool which somewhat used for production grade checking of circuits. Ordinary users do not need dedicated oscilloscope, a multimeter should serve most purposes. Here is a Basic Arduino Oscilloscope, Which Will Show Plotting on Serial Plotter of Arduino IDE and Analog Inputs … [Read more...]
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...]
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...]
What is SPI? – Serial Peripheral Interface
For Arduino and related electronics prototyping, we need to know some basic theories which make them working. In our previous articles, we discussed about I²C protocol, some basics on UART and discussed some basic around serial communication. Another phrase you'll often come to notice is SPI. What is SPI? Full form of SPI is Serial Peripheral Interface. Serial Peripheral Interface is a bus, a … [Read more...]
