Rain Detection System using Arduino and Rain Sensor A simple Rain Detection System can be easily built by interfacing an Arduino with Rain Sensor. The sensor will detect any rainfall falling on it and the Arduino board will sense it and can perform required actions. A system like this can be used in many different fields, such as agriculture and automobile fields. Rainfall detection can be used to automatically regulate… |

Login to Windows Computers using RFID tag and Arduino As many of us know computers were invented around 1871, but it was not until 1961 we had them password protected. Early in the 19’s we used pins and alphanumeric characters as passwords for our computers, today we have many types of verification methods like Password, Pin, Pattern, Gesture, Fingerprint recognition, Face recognition and much more. But still, it is a… |

AC Light Dimmer using Arduino and TRIAC In our household, most of the appliances are powered from the AC supply such as Lights, TVs, and Fans, etc. We can turn ON/OFF them digitally if needed, using Arduino and Relays by building a Home automation setup. But what if we need to control the power of those devices for example to dim the AC Lamp or to Control the speed of the Fan. In that case, we have to use phase… |

DIY Arduino Wireless Programming Shield using Bluetooth Module While doing projects using Arduino, we always need to connect Arduino to PC in order to upload the program in it. But sometimes it is very uncomfortable to always connect the board with PC as if it is a robotics project then you always have to move the robot near to labtop to re-program it. This problem can be solved by programming the Arduino wirelessly. So here we are… |

Sending Sensor Data to Android Phone using Arduino and NRF24L01 over Bluetooth (BLE) Bluetooth Low Energy (BLE) is a version of Bluetooth and it is present as a smaller, highly optimized version of the classic Bluetooth. It is also known as Smart Bluetooth. The BLE was designed keeping in mind the lowest possible power consumption specifically for low cost, low bandwidth, low power and low complexity. ESP32 has inbuilt BLE capabilities but for other… |

Arduino Sleep Modes and How to use them to Save the Power Power consumption is a critical issue for a device running continuously for a long time without being turned off. So to overcome this problem, almost every controller comes with an Arduino sleep mode, which helps developers to design electronic gadgets for optimal power consumption. Sleep mode puts the device in power-saving mode by turning off the unused module. Whether you… |

How to control a Solenoid Valve with Arduino Solenoids are very commonly used actuators in many process automation systems. There are many types of solenoid, for instance, there are solenoid valves which can be used to open or close water or gas pipelines and there are solenoid plungers which are used to produce linear motion. One very common application of solenoid that most of us would have come across is the… |
