RC, RL and RLC Circuits The entire range of electronic components can be divided into two broad categories: active components and passive components. The Passive components include the Resistor (R), the Capacitor (C) and the Inductor (L). These are the three most used components in electronics circuits, and you will find them in almost every application circuit. These three components together in… |

IoT Digital Thermometer using NodeMCU and LM35 In previous Getting start with NodeMCU tutorial, we saw What is NodeMCU and how we can program it using Arduino IDE. As you know NodeMCU has Wi-Fi chip inside so, it can also connect to internet. It is very useful to build IoT Projects. We previously used ThingSpeak with Arduino to make IoT thermometer, but here we will create our own webpage to display temperature.… |

Passive High Pass Filter Previously, we discussed the Passive Low Pass Filter; now it is time to look into the passive high pass filter. A passive high pass filter is an electronic circuit that allows high-frequency signals to pass while blocking low frequencies below a predetermined cutoff point. Same as before, if you look into the name, it shows “Passive”, “High… |

Smart Blind Stick using Arduino Ever heard of Hugh Herr? He is a famous American rock climber who has shattered the limitations of his disabilities; he is a strong believer that technology could help disabled persons to live a normal life. In one of his TED talks, Herr said, “Humans are not disabled. A person can never be broken. Our built environment, our technologies are broken and disabled. We the… |

Arduino Relay Control Tutorial LED Blinking is a very common and almost first program for every embedded learner or beginner. In which we blink an LED with some delay. So today we are here with the same project, but here we will use an AC bulb instead of a normal LED and will blink an AC bulb. You can also drive into this project of Relay Interfacing with PIC Microcontroller. … |
