How to Set Up a 5V Relay on the Arduino

How to Set Up a 5V Relay on the Arduino - http://wp.me/p5wC7n-1KvW

One of the most practical applications of the Arduino is controlling devices like box fans, light bulbs, and other home appliances. Since the Arduino operates at 5V, it cannot control these higher voltage (120-240V) devices directly. However, we can get around this problem by using a 5V relay to …

Controllino è un dispositivo logico programmabile open-source (PLC) costruito intorno ai microcontrollori ATmega328 e ATmega2560. E’ stato recentemente finanziato su Kickstarter per permettere ai Makers di progettare e controllare numerose applicazioni dell’Internet delle cose (IoT), industriali e domotiche. In particolare, offre la possibilità di implementare vari sistemi in molte situazioni quali droni ed elettrodomestici. Il PLC Arduino-compatibile è certificato CE, ed è stato progettato dal team SG-Tronic; attualmente lo si trova sul mercato con tre modelli: Mini, Maxi e Mega. Introduzione Il PLC è il componente base nel mondo dell’automazione industriale grazie alla sua robustezza. Con il tempo è entrato anche nell’uso domestico, come per esempio nei quadri elettrici a valle di interruttori magnetotermici. Le caratteristiche principali ne permettono l’utilizzo […]

Little update on the build of the 3 channel dew heater control module with ambient temperature and humidity sensors. All in parts cost of £40. It has three temperature probes, DewPoint, Ambient and Midpoint algorithms with adjustable band offsets. It takes 3 dew-not heater strips and can be remotely controlled via USB or Bluetooth #rbrown #edgehd #celestrondx #arduinonano #arduino #Dewcontroller #dewcontrollerpro2 #control #interface #dewnot #cgem #electronics #pcb #diydewcontroller #diy #astrophotography #astromony #space by andywad @ http://ift.tt/1QZcy4D

Does such a device exist? Need advice for a research project X-post from /r/audioengineering

I’m trying to build a device for a graduate research project which encourages walking with a symmetric gait.Pretty much I need to take a song (Lets say 60 Beats per minute for ), and chop it up into 1-second increments (samples, tracks, whatever the lingo is). Then I need to make it so that when my input device (I’ll be using a set of pressure sensors in a pair shoes) is triggered it plays the next sample in the sequence.The effect will be is that if the person walks exactly to the beat (60 BPS) it will produce a seamless song if not, it will be choppy and unpleasant to listen to.And if someone thinks they can do this for me, PM an estimate and we can work something out.Original thread at /r/audioengineering via /r/arduino

1st Assignment of Human & Computer Interaction and Interfacing (IMKA)

One of classes I take this semester is Human & Computer Interaction and Interfacing (IMKA). As the first assignment, we are given an Arduino project which utilize (any) sensor and (at least) two seven-segment display. The project should be done in a group of four (by our choice). My group consists of Astarina Natyasari, Eveline Purnomo, Jessica Nathania, and me.

We decided to create a project which display distance detected by ultrasonic sensor on seven-segment displays. For this purpose, our group used the following components:
- an Arduino Uno
- an Arduino USB cable
- 3 seven-segment displays
- a breadboard
- a set of jumper cables
- an ultrasonic sensor

The first thing we done was making sure all the components worked as they should be. The components we used haven’t been touched for almost 1,5 years, hence there were chances that the components broke down. We create a circuit and uploaded basic seven-segment Arduino program to do the test. Below are the pictures taken while we tested our seven-segment displays and arduino.

As we can see on the photos above, it can be concluded that most of the seven-segment displays, Arduino, breadboard, and the cables worked just fine.

Next, we did trial and error on how to display numbers on more than one seven-segment displays. The problem with two or more displays is the lack of pin available on Arduino Uno. Each display needs eight pins, thus two displays connected separately) would need sixteen pins. Meanwhile we also need additional four pins for ultrasonic sensor. Add them up and we need total of (at least) twenty pins for the project, which was barely possible with arduino specifications. Thus, we tried to put corresponding display light on series, then connect only one display to the Arduino pins. This method enabled both seven-segment displays show numbers simultaneously. However, it only work if we want to show same number on both display (which is not the case with the project). Hence, we tweaked the cable around in a way that the cable connected to ground on seven-segment displays got placed on analog pins in Arduino instead of GND pin. The basic idea was still letting both displays got the same number command at the same time, but keep only one display on at a time (by turning off other displays).

For example, we want to show number ‘12′ on the displays. First, we will command both displays to show number ‘1′. Soon after that command, we turn off the second display so that only the first (left side) display showing the number by give digital output on the analog pin (the one ‘tweaked’ before). After a certain amount of delay time, we give another command to both displays to show number ‘2′. Again, we only keep one display on; only it is the right display one we keep it on. In the end, we got number ‘12′ shown. The number shown might not perfect all the time - instead, we got them blinking rapidly in way that we can still read the number easily. To keep them blink faster, put lower number on delay time.

For the next step, we tested the sensor by running a simple program that showed the distance measured by the sensor on the serial monitor. At first, we thought the sensor was having some problem since all the monitor show was -1, which means nothing on its sensing range even though you wave things in front of it. It turned out the problem lied on two things: 1) there were some mistake on making the circuit involving the sensor, and 2) there were some overlapped pin assigning (which involved pin initially assigned for the sensor). After making sure that the sensor was working fine, we combine all the components for the project. Here is the link to ultrasonic basic (testing) code:

https://github.com/alicializbeth/IMKA/blob/master/Ultrasonic.ino

The number assignment to the displays involved some basic arithmetic expressions like div or mod. First, we successfully displayed the measurement on two displays.

Here is the link to the demo video:

However, as the cables were quite messy in length and arrangement, they easily fell off the pin and cause some light not turned on. While we tidied up the cables, we also did additional arrangement to connect the third display. With the same basic step, we managed to show distance measured by ultrasonic sensors on three seven-segment displays. Below is the video of us testing our project.


You can find the link to our codes on this link:

That’s all about this project. Hopefully it is clear and helpful enough! :)
