Smoke Detectors are very useful in detecting smoke or fire in buildings, and so are the important safety parameters. In this DIY session, we are going to build a Smoke Detector Circuit which not only sense the smoke in the air but also reads and displays the level of Smoke in the Air in PPM (parts per million). This circuit triggers …
Recently I started playing around with DHT11 Temperature and Humidity sensor, at that time around, I had an idea to make a small yet effective Weather Station, so in this project inscructable, we will use the DHT11 sensor from the previous tutorial and turn …

In this Instructables I am going to explain about my new project called ” A Pocket Sized Touch Keyboard” .It is a Arduino based small physical device used to simplify your different keyboard operations.You plugs it into your computer usb port and touch it on the capacitive touch sensor,the sensor can be made from any …
MIT has developed a fantastic visual programming language called Scratch. It is also an amazing learning tool for children, because it is simple, cute, and by providing interaction with the real world by a board called “Scratch Sensor Board”. This Instructable shows the development of a shield for Arduino that can interact with Scratch and replicates the functions …
Are you constantly being scared when people sneak up behind your back? Do you have bad hearing and can’t hear people approaching you? Do you want to just build a super fun Arduino project? If you answered yes to any of those questions, then this project is for you! I have a workbench in my …
I wanted to make an easy and secure way to enter my garage. RFID was the best way to unlock my door, even with my hands full I can unlock the door and push it open! I built a simple circuit with a basic ATMega 168 Arduino chip and a ID-20 RFID reader to control …
NOTE: This Instructable is currently incomplete. I will finish it before September 19. I started this project after seeing Nick Johnson’s Turing Alarm clock. I found that the PIC chip he used was a little too advanced for me, so I decided to use the Arduino microcontroller. The original project by Nick Johnson can be …
Way back in the year 2015 we designed a Simple Dual Axis Tracker for use as a fun student or hobby project. It was small, noisy, a little complicated, and provoked a lot of really weird community comments. That being said, three and a half years later we’re still getting emails and phone calls from people all …
In this project I will show you how to build a very simple security system for all kinds of rooms. It might be simple but still effective. It is based around an Attiny85 and uses a reed switch and a key switch as inputs to see whether an intruder has accessed the room. A buzzer …
Reginald started from the simple, yet bold idea to control a bot from anywhere in the world with a live video feed. What I wasn’t expecting was for Reginald to develop into an involved, feature rich project. With my work and money, I was able to complete a project exactly to my satisfaction and more. …
