NTC and PTC are known as thermistors, which can be further known as temperature-controlled resistance. Now something is related to resistance but how it works and which type of circuits can be designed using these components. Let’s know the working concept and then we will use them practically. The value of these thermistors is not…
Previously, I designed an esp8266 shield. And today we will about to know that how to program this esp8266. Because our shield has the same pinout as it is in ESP breakout. Now we will see how to do make all the connections and how to setup Arduino IDE for esp8266 boards. I ordered SMT…
I made 2 different oscilloscope and these are featured on this platform. And now I came up with an idea of dual channel oscilloscope. This one has main microcontroller as Arduino and 1.3” OLED display. This time I also have battery operating options and onboard charging circuit also. You can make this on breadboard first…
Hi guys, Today we are going to make a SPY Wi-Fi camera using ESP32-CAM. I have some ideas to install that camera in a Led bulb cover or phone charger. Because some of the products related to this is also available on amazon. But I want to see the data over Wi-Fi or Internet. And…
Hello guys, today we are going to make this RGB ring using Neo pixel led’s. we will learn, something new about Neo pixel, how to operate them, how to show different animations and how to make your own RGB neo pixel ring. In last we will control them using Arduino Nano board and make some…
hello guys, today we are going to make a smart talking voltmeter. This one is built on Arduino and gives the reading by speaking itself. This function is cool and attractive because when we are working on circuits, we have to see again and again the readings and then switch the voltmeter leads to measure…
Hello guys, today we are going to have a look on, How I made an Arduino based FM and then turn its circuit into a fully functional PCB. In this tutorial you will learn, basic FM working, Arduino code for this FM, range, speakers, antenna and amplifiers used in this circuit. This type of digital…
