DHT11 Humidity, Temperature Sensor: How to Use and Interface with Arduino
We are now going to talk about one small cheap sensor that we call DHT11, and we can use that for measuring humidity and also temperature. You can see that many Arduino people like this sensor because it is very simple and also very low cost, so anybody can buy and try. The DHT11 can […]
IC LF155, LF156, LF256, LF257, LF355, LF356, LF357 Datasheet and Working
These ICs LF155 LF156 LF256 LF257 LF355 LF356 LF357 all belong to one big family of JFET input operational amplifiers. These are special op amps that give very high input impedance, very low input bias current and good DC accuracy. You may think why they made so many numbers, but the reason is that each […]
Isolated High Side Gate Driver Opto-Coupler HCPL3120: No need of Bootstrapping Capacitor/Diode
In this article I will be talking about this device that we call HCPL3120 or also J312, and we see that it is an isolated gate drive opto coupler which we can use for driving H-bridge MOSFET and IGBT gates safely from the low voltage logic side to the high voltage power side. It has […]
Servo Motor Working Explained
We know that servo motors already exist for very long time and we also see that many people use them in many applications. These motors look small but they give big power and also they save lot of energy. So now many people who like electronic things and who want to understand more about such […]
