Arduino Data Logger Shield Features The Arduino data logger shield can be used to make a connection between an Arduino and an SD card. In fact, this module can be used to store Arduino data. It is very suitable for storing data when the Arduino power supply suddenly shuts down. This module also has a DS1307 module as RTC for keeping time and date. The communication protocol for RTC is I2C and for SD card is SPI. Arduino Data Logger Shield Pinout This module is pla...

Overview Most people reading this article are probably familiar with Arduino or at least have heard the name. In this article, we try to introduce this platform in more details and study it from a critical point of view. Furthermore, we will point out the features we have come to discover in our experiences that have not been appropriately addressed. In the first section of the article, we discuss Arduino’s past, why and how it came to life and then study its components. In the second section, we b...

Overview In this project, We’ll try to get some information from human body by using simple sensors and Arduino. You can use these information to create a lie detector machine What You Will Learn Know Polygraph and basics of measuring and recording physiological indicators. Will be familiar with Lie Detector systems. Can get data from sensors and analyze them by Arduino. Can measure respiration rate by using ECG electrodes and impedance pneumography. ...

Active Buzzer Features A buzzer is a device used to produce sound. There are two types of buzzer: active and passive. In the active model, buzzer starts playing sound only if connected to a power supply, but in the passive model, we need to send a pulse from the microcontroller to play sounds.  The supply voltage of the buzzer is 3 volts, 5 volts and 12 volts.  You can download the active buzzer datasheet here.
