5 Microcontroller Based Projects You Must Not Miss!

Looking for a microcontroller based project? From our collection of microcontroller based projects, we bring to you 5 super cool projects. Have fun!

---

1. Microcontroller-Based Tachometer

A tachometer is nothing but a simple electronic digital transducer. Normally, it is used for measuring the speed of a rotating shaft. The number of revolutions per minute (rpm) is valuable information for understanding any rotational system. For example, there is an optimum speed for drilling a particular-size hole in a particular metal piece; there is an ideal sanding disk speed that depends on the material being finished. You may also want to measure the speed of fans you use.

2. Temperature Indicator-CUM-Controller

Here is an easy-to-construct temperature indicator-cum-controller that can be interfaced with a heater coil to maintain the ambient room temperature. The controller is based on Atmega8535 microcontroller, which makes it dynamic and faster, and uses an LCD module to display and two keys to increase or decrease the set values.

3. Microcontroller-Based Clock Using DS1307

Digital wall clocks, table clocks and desk clocks with pointer or LCD display are readily available in the market. Here we present a clock that can be built in a small budget using AT89C2051 microcontroller. Additional feature of the clock is that the time display is visible even in the dark.

4. Programmable Industrial On-Off Timer With RF Remote

Microcontroller-based embedded systems play major role in industrial automation. One such widely used system is the programmable timer.

5. Wireless Equipment Control Using AT89C51

The circuit that uses microcontroller AT89C51 can control four devices from a distance of upto 30 metres wirelessly. An LCD module is used to show the device number and preset control time at the transmitter module.

[TC] 20 Arduino projects of 2012

While looking for ideas for new some new project I noticed there aren’t many lists of Arduino projects online so I decided to make one and in the last few days I’ve been carefully digging Reddit (r/Arduino) and the Arduino forum until I ended up with a list of 20 Arduino projects.

All the projects in this list follow two simple criteria:

1. They’ve been published/released in 2012.
2. They provide quite detailed info (the more the better).

The second criteria forced me to discard some amazing projects, but I didn’t want this post to be a simple showcase of cool Arduino projects, I wanted it to be an useful reference for Arduino users.

20. arduino-l3dgecomm

This project aims to integrate a 3D world with real sensors and motors, more a proof of concept than a proper project, but still an interesting idea. Project page.

19. Charlieplexed ATTiny LED Christmas Ornament

A custom PCB designed in the shape of a Christmas tree, an Atmel ATTiny45 microcontroller, 5 IO pins, and 20 LEDs make a perfect Christmas ornament. Project page.

18. Sound Alarm

A simple idea, but it comes with quite few interesting features. The device built in this project is a sound level detector which sets off an “alarm” via IR when it detects the sound level is to high for too long. Project page.

17. Sleepy Timer

SleepyTimer is an Arduino-based sleep monitor which uses a 3-axis IMU to infer nightly sleep patterns. It graphs the results on an LCD and on a thermal-transfer printer. Project page.

16. Polar Plotter

A polar plotter is a plotter with a rotating, extendable arm. The construction is powered by an Arduino Uno and Maker Beams. Project page.

15. Lite Brite LED clock

An instructable that shows you how to make a Lite Brite clock using a Lite Brite, an Arduino, 46 LED’s and a few other miscellaneous parts. Project page.

14. Game Controller

A game controller powered by a Teensy microcontroller. No project page, but a photo gallery and the source code are available.

13. MP3 Player

Mix an Arduino Mega, an MP3 decoder, an SD card, and a nokia LCD with thousand lines of code and you’ll get a working MP3 player. Project overview.

12. Recognizing token image with camera

Devices built using LEGO always have something special… this one uses an Arduino Nano and an old webcam to recognize digits from a security code. Project page.

11. Reddit message indicator

This project could be useful to all the Reddit users, it’s a small desk notifier that lights up when your Reddit account receives a message. Project page.

10. PIP-Boy

A PIP-Boy is a device used by the protagonist in the popular Fallout series of video games for navigation, radiation detection, data storage/playback, and inventory management. This instructable explains how to make one. Project page.

9. WiiChuck steered laser pointer

This project uses a Wii Nunchuck to control a laser pointer moved by 2 mini servos. Project page.

8. RCArduino Yaw Control

The aim of this project is to make race RC cars more stable and easy to drive especially for beginner drivers. Project pages 1 and 2.

7. Disco Planet

 A huge disco ball made of 800 LEDs. Project Page.

6. Hacking hotel room locks

Last summer a black hat called Cody Brocious (aka Daeken) managed to gain access to 4 million hotel rooms with Arduino board. Probably not an usual project, but it definitely deserved a place in this list! Paper and PDF slides available online.

5. Hidden light control

Controlling a LED strip with an action figure of Ezio Auditore (Assassin Creed) is pretty cool, isn’t it? Project page.

4. ExpeditInvaders

A simple bookshelf can be strongly enhanced by some LED modules controlled by an Arduino board. Project page.

3. Pumpktris

The perfect project for Halloween: combining a pumpkin with the classic video game Tetris!Project page.

2. The Inebriator

An Arduino powered cocktail machine, with plenty of cocktails to choose from. Project website.

1. Pinokio

Pinokio is not just a lamp, it’s a beautiful animatronic powered by Arduino, Processing and OpenCV, which is aware of the environment around and expresses different behaviours in an incredibly natural way. Project log and in-action video.

Bonus project of 2012: Arduino cake

A lucky guy got this from his mum on his 18th birthday, unfortunately no schematic or sketch code are available, but you can check his forum post and maybe ask him for the recipe. 

And that’s all for this list of 20 Arduino projects of 2012!

What’s your favourite one? Can you suggest any other awesome project? Just leave a comment below

Fridge Door Open Alarm

It beeps if the fridge door is left open for too long or hasn't closed properly, to stop food from spoiling. There are lots of other uses as well. A refrigerator or freezer door that is left open or ajar may cause the food contents to spoil. In some cases, the internal temperature of the fridge or freezer will be maintained if the refrigeration system can cope with the open door.

Complete project:



But without the door sealing in the cold air, it may be a losing battle. Running costs will certainly rise. Typically, refrigerators and freezers are in constant use in the summer months and so it is important to ensure that the door is not open for any longer than is necessary. Otherwise the fridge or freezer will not be able to keep the contents cool. And it will cost more money to needlessly run the fridge’s compressor in a futile effort to keep the contents cool.

Circuit looks like:



Even the most diligent fridge user may sometimes leave the door of the fridge or freezer open without realizing it. And tilting the fridge or freezer slightly backward so that the door will fall shut is not completely fool proof as there may be an obstruction inside the door. The obstruction could be because an item inside the compartment has moved or fallen over or because the compartment is too full. This is where the Fridge Alarm is useful.



It warns when the door of the refrigerator or freezer is left open for longer than a preset time period. It is great for indicating when someone is standing with the door open for too long and a real asset in warning when the door looks shut but is still partially ajar. The fridge alarm operates by detecting when any light enters the compartment area. Therefore it is just as useful for freezers (which normally do not have a light) as it is for fridges (which normally do). As long as there is some ambient light which the alarm can react to, it will operate.

Parts layout:



PCB layout:



Circuit diagram:

The alarm will sound if the light is present for longer than the preset period and will continue to sound until the door is closed. In practice, the preset period is adjusted so that in normal use the alarm will not sound. It will sound when the door is left wide open for too long or if left slightly ajar.

Note:

    You don't have to house it in a transparent box, as we did . . . but if you don't, you'll need another hole in the appropriate place on the box wall so light can strike the LDR inside.
