Learn electronics, coding, and projects — step by step.
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 […]
There are actually a lot of GSM module available in the market but I personally recommend and prefer SIM800L due to its size and simplicity. It has a small footprint so it occupies a very small space. This is because SIM800L only provides the basic core of GSM. Meaning to say, you need to provide […]
I just want to share this beautiful LCD Menu implementation that you may use to your next Arduino project. The original code is for PIC microcontrollers, and just ported it for Arduino. My apologies to the original author of the source code, all credits goes to you, Sir. VIDEO DEMONSTRATION SOURCE CODE #include “LiquidCrystal.h” LiquidCrystal […]
