Infrared (IR) sensors are normally used to measure distances, but they can also be used to detect objects. By connecting a couple of IR sensors to an Arduino, you can make an intruder alarm. Overview Infrared (IR) sensors are normally used to estimate the distance of an object, but you can also use them to detect the …

This project is about a moisture-sensing automatic plant watering system using Arduino UNO. The system reads the moisture content of the soil using soil moisture sensor and switches ON the motor when the moisture is below the set limit. When the moisture level rises above the set point, the system switches off the pump. The status of the tank, …

In this tutorial, we are building an interesting application using Arduino and PIR Sensor. A Burglar Alarm – is basically an intruder alarm or an anti theft alarm. So this project is all about building an anti theft alarm or an intruder alarm using Arduino and PIR sensor. It is possible to enhance this project with many features …
Here is my instructable on how to construct a pretty simple (for some!) short range infrared rangefinder/range sensor. Infrared rangefinders are very useful in a number of projects. The majority of these come from obstacle detection (in robots) or generally detecting distances! The one shown here is only a simple rangefinder and will only really …

The AAA Robot is a perfect robot for beginners. It is versatile, easy to build, and discusses many of the topics roboticists need to learn, including but no limited to transistor switches, motor driving nad analog sensors. This Instructable includes step-by-step instructions on how to build your very own robot. This robot has two modes, …
This GSM Mobile is used for our Remote Control (for example Gate Control, Temperature Control….). We use the word ‘module’ because, unlike what we did in our remote control projects, this time around the mobile phone is not mounted on a printed board, but rather on a small auxiliary board which is then inserted in a …
Do you want to control your TV and several other gadgets that are IR controlled? Ya but my phone doesn’t support it because it doesn’t have an IR blaster.Don’t worry here a gadget that gives IR control to any phone and the thing it needs …

Squirt is a motion activated water cannon using Arduino. This was designed for use in the garden but as it’s winter we tested it in the bathroom. It works! True motion tracking is expensive and complicated so this system activates when the victim moves into range and randomises the position of the cannon and the …
A quick circuit showing how to control the speed of a DC motor with a potentiometer with your Arduino board. Also shows how to use a TIP120 transistor to allow the Arduino control a larger power supply. Transistors are 3 pin devices, which via the 3rd pin (Base) allow it to control the current passing through the other 2 pins (Collector and Emitter). …

In this project, we will show how to build a vibration motor circuit. A vibration motor is a motor which vibrates when given sufficient power. It is a motor that literally shakes. It is very good for vibrating objects. It can be used in a number of devices for very practical purposes. For example, one …
