| FLAJZAR.cz. Can you move over? The 74HC595 8 bit shift register. OK, so say you have this crazy cool idea where you need to control a ton of LEDs (I know, I know… LEDs). You looked at the multiplexer article, and that was great, but this idea is so cool, you need individual control of each LED, and turning them on one at a time just won’t do. Well again, we are here to help, and now it’s time to introduce you to the Shift Register. Not just any shift register, the super cheap, incredibly awesome 74HC595 8-bit Shift Register! What does a Shift Register do? Basically a shift register will, in the end, let you expand on the digital outputs you have on your mictrocontroller. But the way it works is a little confusing to think of at first, and these are helpful enough that it is really worth understanding what the heck is going on under the hood.

You can imagine a shift register as a row of chairs. Now, every 10 seconds or so, someone rings a bell, and everyone has to get up and move one chair to the right. How does this let me control LEDs again? Code. S1D13700 Library, Schematic, and Example Code | CafeLogic. Example S1D13700 Graphic LCD Breadboard Set-up This is some example code written specifically for the Powertip PG320240WRF-HE9 320×240 Graphic LCD but it should work with any S1D13700.

Rh_count. Relative Humidity Measurement using the Humirel HS1101 Sensor Arduino, BasicX BX24 and PICAXE-18X copyright, Peter H. Anderson, Baltimore, MD, Nov, '07 (Nov, '07). Introduction This discussion focuses on a relatively simple technique for measuring relative humidity using a sensor. It is desireable to measure temperature as people are usually interested in both the relative humidity and temperature. Advantages of this technique for measuring relative humidity are that it is inexpensive and as the input to the processor is a pulse train as opposed to an analog voltage, the RH measurement circuitry may be located several hundred feet from the processor. I offer a small assembled package, consisting of a HS-1101 sensor, TS555 (SGThompson), 49.9K and 562K one percent resistors for the 555 circuitry, and a separate 10K NTC thermistor for measuring temperature. In the above I have illustrated the powering of the humidity board using a processor output.

Arduino. BasicX BX24. Arduino Home Control. What started out as a simple way to open my garage door from my iPhone turned into what you see here. As of this writing it can be used to open/close the garage door, check the status of the garage door, arm/disarm my security system, and send email alerts. The heart of this system is (obviously) an Arduino, but no ethernet shield was used. The Arduino is controlled via serial commands from a php script running on my home web server. That same server has a python script running that listens for serial data and saves the status of the door and security system to text files for displaying on the website. The python script is also sending emails when it sees the door open. My next step is to try to control my heating and a/c. This site will be kept up to date with the latest information on my Arduino home control system.

***Updates*** Arduino — CMD-c && CMD-v. Using an Arduino + acceleromter to monitor sleep June 20th, 2010 — Arduino, C, Code, Hardware, Python, Software I have heard that a trip to a sleep doctor entails hooking up a bunch of sensors to you and they tell you things like how many times you woke up in the night. I don’t have a bunch of sweet EEG nodes, but I realized that I could easily create something that measures my relative movement throughout the night. Looking at an over-arching chart would probably give me a good idea of how I was really sleeping. The Parts I am currently working on a system which involves control theory and I purchased one of these IMUs from Sparkfun. Sparkfun Razor 6DOF IMU This is a 6 degree of freedom inertial measurement unit.

Accelerometers are really simple devices and they have become completely ubiquitous. The Build Hooking up to the accelerometer is pretty simple. Boarduino + IMU wired The Code The client code is just a single python script. All you need to change is your FTDI_USB location. The Results. Make: Arduino. Dispatchatron Project video at For my son's fourth birthday, we decided on a fire truck... Cheap Arduino Wireless Communications. I was looking for a way to handle wireless communications between two Arduino boards. Other options like Xbee or Bluetooth were going to cost $50 to over $100. Then I found a cheap RF transmitter and receiver at Sparkfun.

The total cost is only $9! Here are a few limitations to RF solution: Communications is only one way. If you wanted two way communications you’d need to buy two receivers and two transmitters which would raise the cost to $18. The advantages are that it is cheap and it is pretty easy to use. Below are some images showing how I hooked up the receiver and transmitter to two different Arduino boards. Here’s a picture of the my actual bread boarded circuit.

Since the receiver is constantly picking up random noise I add a few extra bytes to every data packet. I broke the Arduino code into two files. I did all of my initial testing without any of these improvement and everything worked fine with these devices inside the same room. Add an antenna. Permalink. Scooterputer. I spend a fair amount of time zipping around town on my scooter, and thought it would be cool to add a voltage monitor to warn when the battery might need recharging. Waiting until the electric starter no longer works is somehow lacking. So after an evening with an Arduino Duemilanove, I had a simple programmable voltage divider with 3 LEDs indicating battery low, good, and charging. Done. That's when I saw Liquidware's very cool TouchShield Slide OLED display with touch screen. It was telling me it wanted to be on my scooter. It's a bit overkill for just battery status, so I added temperature and time/date readouts.

You can see in the first photo that the TouchShield display is separated from the Duemilanove / Cell Module / Sensor shields. Sensor Shield The sensors are mounted on a Proto Shield PCB from Ladyada's Adafruit Industries (which is also where I get my Duemilanoves).

LED Matrix - LEDMS88R. [PoBot] Capteur d'humidité résistif. Un capteur d’humidité résistif (ou humidistance) permet d’évaluer l’humidité dans l’air au travers d’un simple dipôle se comportant et se connectant comme une résistance. Pour notre test il s’agit du H25K5A de Sencera : Il coûte un peu moins de 4€ chez Gotronic et c’est un bon moyen de réviser l’acquisition d’une résistance, et comment on peut implémenter une table de correspondance dans un microcontrôleur (look-up table). Datasheet H25K5A Circuit de connexion au µC On utilise deux résistances : l’humidistance (nom générique du capteur) en pull-up connectée à l’alimentation 5 volts et une résistance en pull-down connectée à la masse. Entre les deux résistances, on obtient une tension de sortie du montage qu’on connecte sur un convertisseur analogique/numérique (tout bon microcontrôleur en est pourvu, avec plus ou moins de précision, 8 bits chez Pic et 10 bits chez Atmel).

La formule de calcul de la tension est donnée dans le petit schéma ci-dessous : Calcul de résistance Le montage Les tests. Bildr. Processing (fr) DS1307 RTC tutorial. Base PC USB-XBee autoalimentée. Date d'initialisation : Mai 2007 État actuel : Terminé Sommaire Description générale Mise à jour du 30/03/2010 Le schéma et le routage ont été mis à jour pour mieux prendre en charge la totalité des signaux de contrôle de flux, afin de rendre possible la mise à jour du firmware du Xbee via cette interface. L'idée générale de ce montage est de permettre une communication série sans fil entre un ordinateur et vos montages et/ou vos robots.

Non seulement il vous sera possible de communiquer par une liaison série sans fil avec vos montages et vos robots, mais vous pourrez reprogrammer vos micro-contrôleurs à distance après mise en place d'un bootloader ! Les XBee de Maxstream sont de formidables modules : ils permettent à vos applications de communiquer avec une liaison série sans fil (entre autres fonctionnalités) pour un prix raisonnable et pour un encombrement réduit. Le tout est intégré dans un petit boîtier disponible chez Farnell sous la référence 930180. Photos boitier.jpg facade_avant.jpg.

Dirt cheap wireless « CHEAP, FAT and OPEN. Looked around on the shiny shiny internet, and thanks to this thread in the arduino fourm (and my advisor david mellis) i made this neat little wireless connection: its super simple (and CHEAP!). Super nice thing is that you can block the signal with your hand (mirrors? Lenses?) This is real cool for my project, as this means that you can jam musical data coming from one unit to another. jam as in trash / mash up. also one unit will interfere with another. yeah: data chaos!

Below is pictures of the setup / schematic and code: transmitter: TX code: receiver: RX code: //dirt cheap wireless RX void setup() { Serial.begin(2400); pinMode(13, OUTPUT); } void loop() { // if incoming serial if (Serial.available()) { readSerial(); digitalWrite(13, HIGH); } else { digitalWrite(13, LOW); } delay(10); } void readSerial() { char val = Serial.read(); Serial.print(val); } Like this: Like Loading...
