Thousands of lives are being lost every year due to IEDs (improvise explosive devices). IEDs were responsible for approximately 63% of coalition deaths in Iraq. ABSTRACT Mobile Explosive Containment Vessels (MECV) referred to as Total Containment Vessels (TCV) are fully enclosed vessels used to absorb the explosion forces the enclosure is spherical and made of […]
This page explains how to build an RFID reader with just an Arduino (Nano 3.0 was used in testing, but other models may be compatible), a wire coil made by hand, and various affordable common components. Credits The hardware and software designs for this project are based in part on the ideas, code and schematics […]
4D Systems makes some really nice serial OLEDS. They aren’t hard to use, but the documentation for them is very scattered. This tutorial pulls together the various pieces i’ve found so that you can get up and running very quickly. Start by skimming through the user manual for your particular 4D OLED. µOLED-128-GMD µOLED-96-G1 µOLED-160-GMD1 […]
Introduction This design project utilizes an Arduino MEGA2560 with an ATMEGA1280-16AU microcontroller to create a digital clock. The clock will be able to save time when disconnected from power, and it can be powered from a USB connection or from the wall outlet. The clock displays the hours, minutes, and seconds with an AM/PM indicator. […]
As thefts are increasing day by day security is becoming a major concern nowadays. In this project we will make a digital door lock system with keypad using Arduino Uno. It will open your door only when the right password is entered and it will start beeping when a wrong password is entered. Components Required 4×4 […]
In this project, we are going to make a Digital Thermometer using Arduino Uno. We will use DS18B20 temperature sensor to sense the temperature and Nokia 5110 LCD to display it. DS18B20 is a 1-Wire digital temperature sensor manufactured by Maxim Integrated and is capable of reporting degree celsius with 9 ~ 12 bit precision. […]
Servo Cable The continuous rotation servos that come with the BOE Shield-Bot have a 3-wire cable for connecting it to the power and controller. The black wire is the ground, the red wire is the power (positive) and the white wire (sometimes yellow, depending on the servo) is the signal wire. The signal wire is […]
Schematic Since the IR Sensor uses a light sensor, the schematic is very similar to that of the light sensor. The only difference is the addition of an IR LED and that the IR detector requires connection to 5V and ground. Breadboard Setup To setup the sensors you will need: 2x IR Detectors 2x IR […]
Concepts So you know what a switch is, but what can you do with it? One of the uses of a switch is to tell the controller to activate/deactivate different components. In this case we are going to use the switch to turn on and off an LED. We will do this by checking to […]
There is a wide application of linear actuator where one wants to move something but they do not want to physically get involved in moving it. There are quite a number of ways to control linear actuators depending on the application and the user experience required. These are the key aspects determining the setup and […]
