DIY Current meter using Arduino

There are many methods to measure the DC current. Hall effect sensors and dedicated hall effect current measuring ICs are available to measure Current precisely. But in this tutorial, we are going to cover very basic method to measure current using shunt resistance in the circuit. We will also make our own current sensor and…

NTC v/s PTC Difference And Applications

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…

ESP8266 Wi-Fi based 7-Segment Display clock

Hello guys, I made want to make a 7-segment display. But this time with bigger digits and RGB effects. Because this can be used to display some readings like Clock with Nodemcu, temperature monitoring using Arduino. Also, with an option of color changing after each second or next reading. I also have the similar one,…
