Build temperature & humidity & smoke alarm system based on ICStation Mega 2560 compatible with Arduino( Cost is USD32.39 ONLY) . The working voltage of this system is DC5V.It can measure the current temperature, humidity and smoke. It can display real-time data by the 1602 LCD and can realize the sound and light alarm when in the dangerous temperature and humidity. It is a simply and easily to operate monitoring alarm system about temperature humidity and smoke.
I want to show you, how you can program your Arduino with your Android device. It is very simple and cheap. Also it allows us to program our Arduino where ever we want, this is usefull for permanently installed Arduino boards, like in light controllers...
The xPico WiFi Shield supports simultaneous wireless LAN client connectivity and access point (AP) functionality. This makes it easy to securely connect to an Arduino microcomputer using web-based tools and interactive applications on smartphones or tablets. Its built-in controller ensures that there is no need for a wireless LAN driver on the Arduino microcontroller to configure wireless connectivity.
Roboartist is a 4 stage robotic arm that can sketch out the outline of any image using a pen/pencil on an A3 sheet using a modified application of the Canny edge detection algorithm. The project relies on the core engine to extract the edge from the image uploaded for processing. An Arduino Mega controls the servos using information sent from MATLAB (Fret not, a more open implementation is on the way) via the USB/Bluetooth port.
Garlow is a mini GPS Watch that is based on the Arduino Nano board. It’s not really that “mini” compared to other commercial GPS watch like the Garmin, but I really made a great effort to bring the size down. In fact it looks more like a GPS clock. The first version Arduino GPS logger I built was based on the Arduino UNO, and it was larger than 2 packs of poker cards stacked together. It works just as well as a Garmin GPS watch.
in this project i want to show and explain you a range sensor with ultrasonic and a 20x04 lcd screen. I wrote the code for this project myself and added lots of comments, so that everybody can understand it and use it for other projects (maybe a light range sensor?!). It is easy to build and much more easier to program, it just requires a few cheap parts and can run on battery, for a portable rangefinder.
When I was a kid, I loved playing with Estes Rockets, so I decided to get back into the hobby but using all of my maker skizzls. So here's a really cool Arduino Rocket Launcher launching 3D Printed rockets from my MakerBot Rep2! Enjoy! Fully Open Source for anyone to make!
After I built the tiny balancing robot using an IR sensor for stabilization, there was a comment on the youtube video about how it would be a good thing for kids to build and learn about PID controls. I thought that was a great idea, the only problem was that that tiny robot was the simplest of balancing robots. It was just an on off switch for telling the motor which way to move. There was no actual PID implementation in that system. So that got me thinking about how it would have been really cool if in one of my classes where I was learning about control theory I had a robot that actually let you see the changes in a PID system in real time. I decided to take it upon myself to create such a robot.
As a person without a car, I don't need to carry keys around everywhere I go. Because of this, I've been locked out of my own house several times. It's a pain to wait for someone with a key, so I thought I would do something about it.
This project is my way of solving this problem, while getting the chance to interface with an awesomefingerprint scanner (aka: FPS).
Also, this module isn't restricted to just garage doors, for you can create different kinds of simple motorized locks to suit your needs.
Tetris is a tile-matching puzzle video game released in 1984 and it was the hugely successful handheld version for the Game Boy launched in 1989 that established the game as one of the most popular ever.
Just for FUN, we thought we could build a simple Tetris game by daisy-chaining two of the Bi-color LED Matrix Driver modules together driven by an Arduino micro-controller simply by adapting similar projects found at instructables. We searched through the instructables here but did not manage to find any similar Tetris project to work on.
We expand our search to other online sites and managed to find some information which we adapted to build a simple Arduino based Bi-color LED Matrix Tetris game here.
To build this project, basic electronics knowledge with electronics component soldering skill and some knowledge on using the Arduino are required.
Movies look cool with those EKG (electrocardiogram), the one that beeps and detects heart activities. A few months ago, we had to shoot a hospital scene for our school project. We needed an EKG instrument. To keep the movie authentic, we didn't want to fake the readings so we made the next best thing, a pulse monitor. Since my dad is a doctor he gave me some advice to design the pulse monitor.
Not everyone lives somewhere with central air, or is willing to pay for a Nest or similar "smart" thermostat. The Climaduino is a DIY Arduino-based thermostat designed to control a wall unit A/C. I incorporated both temperature and humidity sensors in order to optimize comfort and reduce energy usage. I then developed a Raspberry Pi-based web interface to control the Climaduino from my phone.
This is still a work in progress, but is definitely functional. I am posting this instructable so others can both build their own smart thermostats, and hopefully build on this project with their Climaduino improvements.
This device was created for a final project for a class by a group of students at Indiana University. As sport fans, we thought it would be really useful to create a tool that would measure distance between two points. This could be used for many different sports, but we focused on golf. A handheld unit that could measure distance in yards from where a ball is hit and where it ends up is really what we were motivated to construct. Distance markers on golf courses are not always accurate and it is very important to know correct yardages to play well. This system could be used to keep track of the average distance for a certain club or to check the accuracy of yardage markers at the course.It works by recording latitude and longitude points of where the ball was hit from, and then calculate the distance from that location to wherever the ball lands.
I am currently living in a college dorm. Like most dorms it's about the size of a tissue box but less comforting. Fortunately, my room has a heater/AC with four positions: low, medium, high, and off. Unfortunately in winter an hour on the low setting makes the room a stifling 80 degrees and when turned off it drops quickly to 60 degrees. My solution uses an arduino, temperature sensor, and motor to automatically turn the heater on/off to keep the room within a desired temperature range. Not only is this more comfortable but it dramatically reduces the time the heater is used, saving lots of energy. (Also note that the motor is only driven to switch the setting and then turned off so no holding energy is wasted.)
ArdaSol is the project name for my solar energy and Arduino based monitoring system. This description shows how the system is built and how it works. The energy production of a photovoltaic plant is monitored and also the consumption or feeding to grid of the energy. Data acquisition during a solar day and publishing on the internet is also a function of this system.
Use a ATTiny85 (can be ATTiny45, ATTiny44) to make an Arduino just for US3.00 and name it as Tiny Arduino.
Tiny Arduino have only eight pins as shown in figure above, Pin4 is ground (Gnd), Pin8 is 5V (Vcc), Pin1 is Reset, Pin2 and Pin3 originally used to connecting the Crystal. In order to utilize all the IO, the internal oscillator (RC Oscillator) is used to replace the external clock which require a crystal. Therefore the Tiny Arduino is now come with five IO. Below shows the Arduino IO functions.
1. There are five IO, each IO can be Input or Output 2. Among the five IO, two of the IO can perform as PWM 3. Among the five IO, three of the IO can perform as Analog Input
I2C may require to extend the features of Tiny Arduino.
Recently, we scavenged an old Lego Mindstorms 1.5 set. It’s fully functional, but the RCX 1.5 Lego software is obsolete and does not run on recent Operating Systems. Besides, the brick has only few in/out ports: 3 inputs and 3 outputs. So, we decided to forget it and reuse Lego parts with an Arduino board.
