Don’t get confused with an RGB clock

przedwczoraj 23:46 | http://www.embedds.com/dont-ge... | ∞

Lots of hobbyists are struggling to make their digital clock designs unique, interesting and bizarre. Craig has built interesting clock where he used RGB LED strip with 14 LEDs. Clock runs on Pro Micro Arduino. Time is clocked at separate RTC chip. ...

Sanguino – when more power is needed

16 Maj 2012 23:26 | http://www.embedds.com/sanguin... | ∞

Standard Arduino comes with Atmega328 chip. It isnt the top notch microcontroller when speaking of number of I/Os or Flash memory. You could go with mega version when real power is needed. But fact is that mega might be too much or simply too expens...

Portable digital stethoscope with record and playback

Stethoscopes are intensively used by physicians. Some of them are modern other are old fashioned. But in many cases technology may help to see what human may skip/not notice. This is why computer aided diagnosis (CAD) is important. Having this in min...

AVR Interprets Morse code

15 Maj 2012 14:06 | http://www.embedds.com/avr-int... | ∞

Morse code is basically dashes and dots. Each character is encoded using a mix of them. Human can learn Morse code during some practice. If you dont want to learn it but still need to decode some messages you can build a simple Morse code interprete...

We all know how sweet sleep can be in the morning. Every last minute counts& If there are kids around then things get different. Simply speaking – they dictate when to wake up and get up. Most frequently this is because kids dont have a sense of tim...

Arduino based alarm system that sends SMS

13 Maj 2012 14:08 | http://www.embedds.com/arduino... | ∞

Alarm systems tend to be more reliable when you can get status messages anywhere you are. Usually such systems uses a GSM modules that are quite expensive. If your protected object isnt very critical you can try simple version like following which i...

Driving Seven segment LED display using serial interface

12 Maj 2012 15:55 | http://www.embedds.com/driving... | ∞

Seven segment LED displays a great way to indicate basic numeric and text information. They are visible in a dark an from larger distances comparing to LCD. Driving one seven segment display is a piece of cake using any MCU. But when it comes to larg...

KLBasic interpreter for AVR

11 Maj 2012 14:08 | http://www.embedds.com/klbasic... | ∞

This Basic interpreter originally was developed by Gordon Doughman and run on Motorola 68hc11 microcontrollers. Karl Lunt admired this work and decided to port it to AVR microcontrollers. He found an ASM source code on internet and converted in to C....

Arduino can now program PIC18

10 Maj 2012 14:46 | http://www.embedds.com/arduino... | ∞

Say you devoted your hobby life to AVR microcontrollers and would like to give a try on PIC. The basic scenario would be to build/get a PIC dev board and also look for suitable programmer. Anyway building one takes time – purchasing also doesnt look...

Software USB for PIC16

9 Maj 2012 14:27 | http://www.embedds.com/softwar... | ∞

Not all microcontrollers have USB peripheral that can be used directly. In fact MCUs with USB tend to be more expensive and more complex. But sometimes you need simple MCU with USB capability. And you dont want to spend additional funds on USART to ...

IR based Arduino programmer

8 Maj 2012 21:21 | http://www.embedds.com/ir-base... | ∞

Wireless programmers may be useful in some cases. For instance where devices are in hard to reach areas or simply to update firmware without leaving your desk. In either case it is a great option for someone. So this is an IR based Arduino programmer...

VFD tube alarm clock

7 Maj 2012 12:08 | http://www.embedds.com/vfd-tub... | ∞

Haris purchased few IV-11 VFD tubes and decided to build nice looking alarm clock. The tubes itself look impressive when lit. Instead of leaving them as is he also added and RGB LED under each tube. This way Haris could fill them with different color...
