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 this … [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...]
Arduino : Make LED ON One at a Time Using a Potentiometer
We Can Use the On-Board ADC to Convert Number Between 0 and 1023 Rotating Shaft. Here is How to Make LED ON One at a Time Using a Potentiometer With Arduino. That means, as we will turn the shaft of the potentiometer, LEDs will turn on depending upon the position. Actually before this project, one should get used with two basic examples on official Arduino website … [Read more...]
What is I²C Protocol? Relevance of I²C in Arduino
Previously, we discussed about UART. What is I²C Protocol? I squared C (also pronounced as I-two-C) or I²C is a bus serial communication protocol designed by Philips for home automation and home electronics applications. Since 2006, licensing fees not needed to implement the I²C protocol. Fees needed to obtain I²C slave addresses allocated by NXP. I²C can connect a microprocessor and various … [Read more...]
Blink LED and Beep Every 1 Second With Arduino
Previously we have shown beep with key press and LED lightening up and projects like Arduino Traffic Light, Arduino TM1637 with RTC. Here is How To Blink LED and Beep Every 1 Second With Arduino. We Will Discuss Many Ways To Achieve The Goal Including Using RTC. Arduino has many ways to count time. Easiest we know is usage in the way we Blink a LED as basic example. Blink LED and Beep … [Read more...]
Solid-State Relay (SSR) For Arduino
In our one previous article we discussed about Arduino Relay Modules. Solid-state relays are not really relay rather are electronic components which has some functions like electromechanical relay. Here is an Article on Solid-State Relay (SSR) For Arduino. Solid-State Relay (SSR) provides limited switching arrangements (SPST switching, terminologies like SPST discussed on our article on electrical … [Read more...]
Arduino Basic Piano For Children (Pushbutton & Buzzer)
In Early '90s Technology Was Limited and Worldwide there Were Few Electronic Toys. This kind toys with 8051 or plain common IC were easy to find. This particular project is not created by us. This project is shared by ExeCuteLi on hackster.io who deserves the full credit. Here is His Arduino Basic Piano For Children With Pushbutton & Buzzer as Components. The original project on hackster.io … [Read more...]
LDR Reading on TM1637 : Example How To Print Analog Sensor Value
Printing serial display is a difficult or time taking work on particular desired display in Arduino project. Te reason is mostly out of cheap China sub-standard components and fight with community made various libraries hunting driver IC. New users often think that issue their fault. No, that difficult is not logical fault. In Case of LCD, Printing Actually Easy. Like We Have Shown Printing LDR … [Read more...]
What is MCB (Miniature Circuit Breaker)? How Household MCB Works?
Definitely, you have noticed switch looking gadget in modern household which automatically becomes off upon fault in line. They are called MCB - Miniature Circuit Breaker. Why These Days We Are Seeing More Usage of MCB in Household than Before? It is Common to Ask - What is MCB (Miniature Circuit Breaker)? How Household MCB Works? In this guide, we hope that we will be able to answer the common … [Read more...]
Control Multiple LED Depending on the Level of Light With Arduino
In our previous guides, we have shown how to control single LED depending on light with Arduino. Also, we have shown that without Arduino, can control LED depending on the level of light. The ways are different but essentially both involves a basic component - LDR. In this guide, we will show how to control multiple LED depending on the level of light With Arduino. It means - with increasing … [Read more...]
