Plants liven up any space by adding a sense of airiness and life. That is – of course – when you don’t forget to water them, and they shrivel up and die. I am very bad at remembering to water plants. That is why I built this self-watering plant to do it for me. Using a soil sensor, and an Arduino-controlled water pump, I have created a system that will never forget to do it.   Instead of remembering to water my plants when the soil goes dry, I only have to remember to once and a while refill the water reservoir. In this way, I have decreased my obligation to these plants and put it off to a much later date. Perhaps further iterations of this device can be connected to a rain barrel so that I won’t even have to worry about refilling my reservoir, and the entire system can be fully automated. [ ]

We all are aware to custom characters used in various display module.Heart,various style of smileys,arrow are the foremost usually used custom characters. Thus during this tutorial we are going to learn how to display custom characters in LCD using arduino uno board. This project is done by using of arduino uno board and 16*2 LCD module. custom character display It is assumed that reader know how to interface lcd with arduino and how to install arduino software.We can generate completely different style of custom character using the below pixel array shown in the image.  Pixel array custom character shown below that is used in our program to generate the smile type character:          {                 0b00000,                 0b00000,                 0b01010,                 0b00000, ...

Do you still remember the H1N1 outbreak in Asia? The manifestations are usually flu-like symptoms which includes fever, cough and colds. The best way to detect fever when people are arriving from the affected areas was to use a thermal camera. These were widely used in Asian countries especially on airports but not all can afford one because it’s very expensive. We can all agree that this is the greatest deal ever! A thermo-cam which costs around 100$, now there is no reason it can’t be bought by even poor countries to help prevent the spread of the disease. Credit must be given to inventions like this because it’s really a big help.

The circuit in this article is an RS232 converter , it is possible to connect an Arduino bootloader or your chip with a RS232 port . Here are two versions, one very simple and functional above and one below a little more sophisticated . The port 232 gives a bit more work than USB , but in case of equipment that only have this feature that is a good outlet .  Converter RS232 to Arduino Circuit Diagram

What do you think of using the good old pic in a 32 Ardino ? This would boost their projects, leaving the Arduino 5 times faster, increasing by four times the memory and still leave the Arduino cheaper. This is a new concept ByPic development of microcontrollers, it is not necessary IDE, no complex code in C, no compiling, no programmer is required, only a serial interface.  The ByPic is ideal for beginners and lovers of rapid prototyping.ByPic PIC32MX150F uses the IC-128 has 128K Flash, 32K RAM and operates at 40MHz. It is a kit of parts that allows you to build, you only need a soldering iron. building when the device is fully programmable by simply using the serial interface.  Once built the controller it will be able to adapt to many projects with servo controllers, stepper motor controllers, robots, Projects clock, timer, times, alarms, automation, etc. ..No software is needed, beyond what is in the IC. He self compiles the text you write and download to the serial port. ...
