Have you ever wanted to make a line following robot but the infrared sensors were too expensive for you? Do you want to upgrade the robot in my other instructable? Well this instructable comes in two stages, Stage 1 is the prototyping stage, where you build the circuit on the bread board and debug it […]

The Particle Photon is a microcontroller suitable for wearable project’s considering it’s small form factor and that it supports OTA updates. For those of you who do not know what a Particle Photon is it is a tiny microcontroller with on board WiFi (Cypress WiFi chip) and the STM32 ARM Cortex M3 microcontroller, which is ideal for cool

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
Moisture Control Unit – MCU Continue Reading
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
Arduino Controlled Motion Sensor Continue Reading
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
VRBOT (Voice Recognition Robot) Continue Reading
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
