Garage parking assistant

Posted on by Leave a comment

Parking in your home garage could be a bit of challenge if you have a bigger vehicle. You would like to make sure when you parked, you had enough space to walk around the vehicle. This Instructable describes an Arduino based garage parking assistant that would allow you to park in your best spot every time.

It uses an ultrasonic transducer to measure the distance between your car’s bumper and the backside wall of the garage. A control box with visual indicators using bright Green and Red LEDs signals you when you are on the exact spot. Prior to its first use, you need to calibrate the sensor by parking your car in the best position that you like.

Analog thermometer

A new project tutorial from educ8s.tv is about making an Arduino based analog thermometer that uses an analog voltage panel meter for displaying temperature.

Today we are going to learn how to use this analog voltmeter with Arduino and make it show the temperature instead of the voltage. As you can see, in this modified voltmeter, we can see the temperature in degrees Celsius. The temperature is measured by this digital sensor, a DS18B20 and it is then displayed on the voltmeter. I really like analog dials like this one, because they give a vintage look to the projects. Let’s now see how to achieve that result.

Arduino powered vending machine

An Arduino-powered soda locker project posted by Mistablik on Instructables can easily fit into his locker and can supply two different kinds of pop. It features a coin acceptor that allows you to use nickels, dimes, and quarters for purchasing the soda.

Lockers just aren’t what they used to be. With so many schools moving to electronic devices for books, lockers become less of a space for your books, and more of a question of: “What am I going to do with this?”

What if you could use that space for your own vending machine? In this Instructable, I’ll tell you how I came up with the idea, how I designed it, how I solved a few problems along the way, and how it all turned out! So pop open a can of your favorite drink and come along!

Fingerprint controlled door lock

Posted on by Leave a comment

This fingerprint lock is described in an Instructable posted by JetLab and is about building an Arduino-based electronic door lock that can be installed on almost any access point in your house. The project uses a keypad and fingerprint scanner to grant access to the users by controlling an electric door strike with a relay.

I started this project because I was wanted to work with a keypad and fingerprint sensor as well as become more familiar working with LCD’s, I also needed a way to lock my door from the outside so I thought an electronic door-lock would be a great opportunity to over-engineer something and learn some cool stuff.

On power up the device displays a message on the LCD and a red status led lights up, indicating that the door is locked. The user then has the option of pressing a button for entering the password or for changing the password. To change the password the user would need to know the current/default password. If the password is input incorrectly then the display will show that the code was invalid and then revert to the default screen. When the code is entered correctly,the fingerprint scanner activates. If the scanner recognizes a fingerprint that has been enrolled then it will activate the relay and the a green status led for a few seconds, enough to open the door, enter and close it.

Personal location tracker

Tiobel‘s Track Me project describes a personal GPS tracker using an Arduino Mega along with a GPS module and a GPRS Shield. The GPS module finds its location using data from more than 3 satellites. In order to retrieve the location remotely, you need to call the number of the SIM card placed into the GPRS shield, and the system will send you back an SMS with the actual position and it’s link to the google maps.
