Sıcaklık ve Nem SensörüDHT22 veya DHT11 sıcaklık ve nem sensörü serisinin iki versiyonu var. Biraz benziyorlar ve aynı pinouta sahipler ama farklı özelliklere sahipler.DHT22, açıkça daha iyi özelliklere sahip olan daha pahalı versiyondur. Sıcaklık ölçüm aralığı -40 ° C ile + 125 ° C arasında + -0.5 derece hassasiyetle,...

Thermometer example: TM1637 4-digit 7-segment display with DHT11 temperature and humidity sensor 4-Digit 7-segment displays are great for displaying sensor readings like temperature, humidity, voltage or speed. In the following example, I will show you how you can display temperature readings on the TM1637 display.We...

4-Digit Clock based on a RTC moduleI have got a DS1302 Real Time Clock Module with Battery Backup, and I was eager to making a digital clock. As I also had a 7-segment 4-digit display, I was looking for the best way to make that clock. But I was always reluctant to use this type of display, because...

My first Arduino project was to build a battery capacity tester. I’ve got a box of rechargeable AA batteries, and it seams they’ve been less and less effective. Since most applications require 4 batteries, invariably one problem battery makes the rest of them look bad. The Atmel ATMega328 microcontroller has 6 analog...

Buck Boost Regulator using XL6009 with Adjustable 3.3V to 12V Output Voltage Buck-Boost regulator is made using two different topologies, as the name suggests, it consists of both buck and boost topology. We already know that Buck Regulator Topology provides a lower magnitude of output voltage than the input voltage,...

Kalp atış hızı , vücut ısısı ve kan basıncı izleme, insan vücudunun çok önemli parametreleridir. Doktorlar ateş veya vücut sıcaklığını kontrol etmek için termometre, kan basıncı ölçümü için BP monitörü ve kalp atış hızı ölçümü için nabız monitörü gibi çeşitli tıbbi cihazlar kullanır. Bu projede, bir dakika içinde kalp...

Abstract The Arduino inbuilt 10 bit ADC, can be used for constructing / measuring the 0 Volt to 1000 Volt user selectable Digital Volt Meter. The 16x2 LCD display driver, connected with Arduino Uno will be used for displaying the measured voltage. This voltmeter can read only DC voltage. ...

M.Pugazhendi build a digital voltmeter using Arduino and MAX7219 display driver. The Arduino inbuilt 10 bit ADC, can be used for constructing / measuring the 0Volt to 50Volt Digital Volt Meter. Popular MAX7219 display driver, connected with Arduino Uno will be used for displaying the measured voltage. This voltmeter...

I found a website that solves all the wiring and coding issues; A library, written by Dean Reading. I downloaded the zip file, copied it to /usr/share/arduino/libraries/ and unzipped it (includes the .cpp, the .h and an example sketch). (The directory is correct for my Linux Mint 16 system). Given this library, the example...

This was a great buy, easy to wire up and surprisingly accurate, when I measured up to 3 metres. I found another blogger who had created the code. The ultrasonic distance sensor and pin layout. ...

Hello world! Today i made a simple and very cheap to build alarm System with a keypad, pir sensor, relay and a very loud alarm strobe. You have 30 seconds time to leave the room after activating the alarm system, of course this can be changed in the code to less or more seconds. Now it has been set to 30000 milliseconds. You...

I got thoroughly fed up with cheap MP3 players 2 years ago, and built my own. It works so well for me. Project completed; December 2014. Updated January 2016 This project was great; there are a number of issues that you will also face, if you choose to investigate this mor...

İşaret, R2 ve R3 dirençlerini bir 4.7k düzeltici ve bir Zener diyot VD1'in olmamasıyla devreden farklıdır. Şebeke voltmetresinin modifiye edilmiş bir devresi de gönderildi, voltmetrenin voltajını stabilize etmek için daha iyi bir devre ile ayırt edildi...

PIC16F676 mikrodenetleyicisindeki bir voltmetreye ayrılmış bir makale uzun süre sitede yayınlanmıştır . Zamanla, bazı ziyaretçiler voltmetrede değişiklik yaptı ve bu değişiklikleri paylaşmaya karar verdi. Bunun için minnettarlar. Makale, PIC16F676 üzerinde yapılan 50 voltluk bir ölçüm limiti olan bir voltmetreyi...

What is a bootloader, and what is bootloading? The bootloader is the little program that runs when you turn the Arduino on, or press the reset button. Its main function is to wait for the Arduino software on your computer to send it a new program for the Arduino, which it then writes to the memory on the Arduino....

If you don't have an easy way to order an Arduino board or kit, you can etch this PCB design by hand and solder it together. It is pin-compatible with the Arduino Diecimila, and should work with any Arduino shield. This is the third revision of the board: the Arduino Single-Sided Serial version 3, or s3v3,...
