CH340 is a very common USB-to-serial interface IC for different purposes. With Arduino, ESP, or even adding a USB-serial port with any microcontroller this IC is a kind of legend now. So, let’s check it out! What is CH340: CH340 is a USB bus conversion chip, it can realize USB to Read more
R503 is a popular capacitive fingerprint sensor. We can use this sensor for industrial purposes. In this article, we’ll make a fingerprint attendance system with R503 capacitive sensor with Arduino. I hope this project will help many people make their own attendance system. So, let’s start! About R503 Capacitive fingerprint Read more
In this article, we are going to learn how to Read ThingSpeak Channel using ESP8266 and Arduino. There are lots of example codes over the internet with data posting to ThingSpeak using ESP8266 and Arduino. But there are almost none that really read the channel feed using the ESP8266 Wi-Fi Read more
In this article, we will write our own code that can be used for ‘Reading SMS with Arduino’. We use Arduinos in different projects. When using GSM modules, we may need to use SMS to give commands to the device. Besides using a big library like FONA, this small code Read more
In this article, we are going to make our own Caller ID detection using Arduino. Usually, there are several libraries over the internet, but recently I had some bad experiences with most of them. That is why I simplified the process so that we can easily integrate this function in Read more
EEPROM is a very fundamental feature of Arduino and it has internal EEPROM for this purpose. But sometimes, we need some more to use. In that situation, some dedicated EEPROM ICs like 24Cxxx ICs. In this article, we are going to interface external EEPROM with Arduino. So let’s start! EEPROM Read more
Let’s make an Universal Semiconductor and electronic component tester using Arduino. We use many electronic components in our projects and different products. Sometimes, you may need a simple electronic component tester that can help you testing some components for you. Here in this article, we will learn to make an Read more
