The FTDI FT232 chip is found in thousands of electronic baubles, from Arduinos to test equipment, and more than a few bits of consumer electronics. It’s a simple chip, converting USB to a serial port, but very useful and probably one of the most cloned pieces of silicon on Earth. Thanks to a recent Windows update, all those fake FTDI chips are at risk of being bricked. This isn’t a case where fake FTDI chips won’t work if plugged into a machine running the newest FTDI driver; the latest driver bricks the fake chips, rendering them inoperable with any computer.
In a presentation at the Maker Faire held in Rome this weekend Arduino co-founder Massimo Banzi gave a preview of the soon to be released Gemma wearable Arduino board. The 27 mm diameter board contains an ATtiny85 processor programmable from the Arduino IDE via Gemma’s micro USB connector. The design is a collaborative effort together with Adafruit Industries who also worked on the Arduino Micro.
This article is a about a fully functional water level controller using Arduino. The circuit displays the level of water in the tank and switches the motor ON when the water level goes below a predetermined level. The circuit automatically switches the motor OFF when the tank is full. The water level and other important data are displayed on a 16×2 LCD display. The circuit also monitors the level of water in the sump tank (source tank). If the level in side the sump tank is low, the motor will not be switched ON and this protects the motor from dry running. A beep sound is generated when the level in the sump tank is low or if there is any fault with the sensors.
As open-source hardware users and makers, we love playing with new chips, boards and tools. And there is one chip which is quite popular these days: the CC3000 WiFi chip from TI. This chip comes with many promises: cheap (around $10), easy to use, low-power … It was featured in many articles around the web, but somehow it was quite hard to use with Arduino as there was no breakout board or library available.
In this Instructable I'll show you how to make a electronic dashboard for a bicycle. We'll be using an Arduino and a few off-the-shelf parts to create a system with light control and an LED speedometer.
I purchased a battery operated smoke/fire alarm few days ago and it showed up today. It runs on 9V and will make a loud sound if smoke is detected. My intention was to hook it up with my home automation system so that I would receive alert if it would go off including SMS, pushbullet notification to my phone, email etc.
Lets start with a warning: this project controls water. Electricity and water really don't mix and there is a real risk of electrocution and or death if you are not careful. Build this project at your own risk and I won't be held responsible for anyone who builds this. make sure you use a battery to power this NOT a mains transformer of any kind. just be smart and be safe.
Any and all damages/injury incurred by the implementation of the information in this publication are the sole responsibility of the end user, I cannot accept any responsibility.
What is this? it is a arduino compatible (ATMEL 328p) based home bathtub controller.
this controller sets the depth, adds bubbles and monitors the temperature of a bathtub based on a user profile. v2.5 has support for Internet of things but it is not fully implemented.
But why? Well why not? ever wanted to have a bath ready at a touch of a button or from your smartphone(coming soon)?
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.
Featuring 3 OLED screens on a flexible circuit board, this minimalist electronic wearable is stunningly bright, likes to be touched and features a rechargeable 10 hour battery. Apologies about the hairy arms (and the dubstep)!
I’m starting to source parts for my nixie tube experiments. I’m in the very early stages of prototyping a nixie clock. My Breakout Boards were a bust, but that’s not stopping me from pushing on with the nixie-tinkering.
I recently started brewing beer at home with a group of friends and one of the things that quickly came to light, is that maintaining a steady fermention temperature can be the key to a good brew. We have a stick on thermometer on our fermenter buckets which we can use for reading the temperature of the beer, locally, but I was wondering if there was a system I could hook up, so that all of us could check in on the beer via the web. Lo and behold, there are a few systems available for monitoring/controlling the temperature of a batch of homebrew beer as it ferments. But most of them require expensive equipment and the ones that don’t are still based on theArduino-sensor and Raspberry Pi-gateway model, which will set you back the bones of €80, if you make it yourself. As well as that, the webserver for the BrewPi system (most popular as far as I could see) runs on the Raspberry Pi in your home network. This means you have to configure port forwarding and something like dyndns to access it from outside the house, making the system configuration a bit of a chore.
Arduino's control small motors very easily; in fact, I've done a number of videos covering How to Control a Servo with Arduino, How to Control a Stepper with Arduino, and How to Accurate Control Steppers.
But another great thing about Arduino's is they make it very easy to control large motors - like the brushed DC gearmotors in this video buy using a motor controller.
There are a thousand of radio stations are broadcasting music/reviews/interviews over the internet. To listen these radio stations you will need a personal computer or tablet or smartphone or a stand alone web radio player.
The circuit I have designed is an inexpensive web radio player with high quality stereo sound.
At the Maker Faire this year I got lots of questions about soil moisture sensors, which I knew little about. So I started seriously researching the subject. I found a few different soil sensors, learned about their principles, and also learned about how to make my own. In this blog post, I will talk about a cheap wireless soil moisture sensor I found on Amazon.com for about $10, and how to use an Arduino or Raspberry Pi to decode the signal from the sensor, so you can use it directly in your own garden projects.
I know GSM controlled home automation systems are widely used and can be found easily on internet, but as we all know, the prices are very prohibitive for general consumers. This is why I've tried to build some sort of device based on open-source knowledge that can be replicate by all the hobbyists, even if they are amateurs or professionals.
So I begun to think what kind of basic home appliances could be remote controlled via GSM network and nothing else? We all know, that you can control lights, heating, multimedia system and so on, but I've tried to make my project closer for my basic needs: lighting and heating (optional - garage doors, but it's not my case because I live on a 3rd floor apartment).
For the last several weeks, I've been working on SPI transactions for Arduino's SPI library, to solve conflicts that sometimes occur between multiple SPI devices when using SPI from interrupts and/or different SPI settings.
To explain, a picture is worth 1000 words. In this screenshot, loop() repetitively sends 2 bytes, where green is its chip select and red is the SPI clock. Blue is the interrupt signal (rising edge) from a wireless module. In this test, the interrupt happens at just the worst moment, during the first byte while loop() is using the SPI bus!
This robot will mow the grass of your garden, staying within a defined area, avoiding all obstacles and working in complete autonomy, automatically charging itself with a solar panel.
In this post we present a robotic lawn mower, powered with solar energy and able to operate just with the clean energy from the sun; this one is a great difference from the commercial projects having a robot in need of a charging station connected to the electrical grid.
