This is a mini article where you are going to learn about an One Button push on push off switch circuit. Sometimes we need a small button switch that can be used as one push switch on, another push switch Read more…
In this article, we are going to learn about Interfacing External EEPROM with a PIC microcontroller. All the microcontrollers do not have EEPROM but sometimes, we need to save some information in EEPROM while the MCU does not have any. Read more…
This is a very common error to them who works with microcontrollers. In this article, I’ll show you ways to solve this Not Enough ROM/RAM error. The high-level MCUs are capable of handling the memory mapping properly. But the lower 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 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. 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 Read more…
In this article, we are going to learn how to make a simple voltage protector for your appliances. A small device can save lots of money, saving your appliances from voltage spike/surge/sag and unacceptable voltage range. So let’s make it! Read more…
Sometimes, you may need to make a DC/DC converter with minor components that can handle small loads. In this article, we are going to make something like that. This DC/DC converter using transistor has only a few components and can Read more…
In this article, we are going to make a Simple Component Detector using PIC16F877A microcontroller. Using the basic working principles of different semiconductors, we can identify the devices. Here, we are using some simple and basic techniques, using these techniques, Read more…
This is a productive post with a voltage stabilizer circuit with 4 relays. A voltage stabilizer is sometimes becomes essential for our appliances if the supply voltage is not stable. Here in this post, you’ll find a product that can Read more…
