In this Instructables, you will see how to Interface Moisture sensor to your NodeMCU. And check the moisture value and the same to be displayed on the LCD. We’ll use Liquid Clear Crystal to display the moisture value. This 16×2 LCD is very popular and broadly used in electronics projects as they are good for displaying information like sensor data from your

With this device you diminish the use of water in your house or work. Instead of waiting to see vapor in the shower to get in, this device help you to know when the water its at the temperature you want and you can instantly enter to the shower. In this way you don’t waste the water
Temperature Sensor for Shower using Arduino Continue Reading
In this Instructable, I’ll be explaining how to build a motion activated alarm! It uses an Arduino microcontroller, a PIR (passive infrared) sensor, and a type of alarm. You can use an LED indicator, a buzzer, or a piezo. That’s the easy part. I will also be showing how to display to a character LCD

In this Instructable we’ll make a robot (more like a RC car) which is controlled by voice i.e. Voice Recognition. Before I start to give you any further details one must know that this is Voice Recognition and not Speech Recognition that means the controller does not understands what you are speaking. This project uses

We all like to know what the current room temperature is, and sometimes what the temperature is in another room, or maybe even in your vacation house on the other side of the world. Maybe you want to monitor the temperature in your pet Lizard’s house? You’ve come to the right place to learn how

Don’t let a clogged drain slow you down!Coming back from our vacation, me and my wife were surprised by the water covering the floor of our apartment, and we found out it’s not even clean water, it’s drain everywhere. After clearing the drain and cleaning the floor, I had this question: why don’t we have

Colour reading is a real issue for industrial models. I’ve been working on it for more than 12 months now, since December 2009. After many months of hard work, • starting with the standard colour reader (season 1 ) with features a red LED, • adding extra light from bulb lamps (season 2 ), •

This fun little project will allow you the trivial joy of letting a electronic network announce that you have rain! The AI controlled, tear eliciting price’d Tesla has been rumored to have sensors that awaken the windshield wipers at the onset of rain. Being in a fully glass-enclosed cabin you would think that the obviousness

The following instructable describes a easy to build and inexpensive device to perform pressure measurements and demonstrate Boyle’s law, using the micro:bit in combination with the BMP280 pressure/temperature sensor. Whereas this syringe/pressure sensor combination has already been described in one of my previous instructables, the combination with the micro:bit is offering new opportunities, e.g. for class

Wireless power transfer systems are well on their way to replacing conventional wired charging. Ranging from tiny biomedical implants all the way to wirelessly recharging huge electric vehicles. An integral part of the research on wireless power is minimizing the magnetic field density. The International Commission on Non-Ionizing Radiation Protection (ICNIRP) provides scientific advice and
