Here we will further our exploration with the SIM800L GSM Module by testing the voice call capability. 1. Send ATD+ZZxxxxxxxxxx;<CR><LF> – this is tell the GSM module to dial the following mobile number ZZ – the country code of the mobile number you want to call xx – is the 10-digit mobile number ; – […]
In this tutorial, we will explore the mouse emulation in Arduino Uno. This should be the part 2 in using the Arduino Uno as Human Interface Device.

In here we will learn how we can use SIM800L DTMF to control anything from simple turning On or turning Off of LED to big projects like home automation. DTMF stands for Dual Tone Multi Frequency or more commonly known as Touch Tone. You will most likely to experience the use of DTMF when you […]
Whatever you are doing with the Arduino is lost the moment you pressed the RESET button or you removed the power. The work around that is to implement some data logging to an SD card or through the EEPROM. So what is EEPROM? EEPROM stands for Electrically Erasable Programmable Read-Only Memory. Each EEPROM address can […]
