Decoding ideas

This image below will guide you to construct an arduino on a breadboard.Here we are using the MAX232 Level converter IC rather than the conventional two transistor circuit to increase the reliability of the communication.

Note:
1.All Electrolyte capacitors are 1 micro Farad.
2.The Ceramic capacitors are 18 Pico farad.
3. The LED is a 5MM LED
4.The crystal is 16 MHz crystal
5.Pin 2,3,5 represents Pins of the serial port
6.The regulator is a 5V regulator

I drew this scheme using Fritzing but the Max232 was not available – so used different IC and then used a photoeditor to change the name of the IC.

Arduino is a physical computing platform based on a simple I/O board and a development environment that uses the Wiring library to simplify writing C/C++ programs that run on the board. Arduino can be used to develop stand-alone interactive objects or can be connected to software running on a computer (e.g., Adobe Flash, Processing, Max/MSP, Pure Data, SuperCollider). Currently shipping versions can be purchased pre-assembled; hardware design information is available for those who would like to assemble an Arduino by hand.(from wiki) and its awwesome

Well for those who want to purchase one from India Look out for the stores below
1.Ashwin venkat (Official distributer)
2.Bhasha-e-store
3.Simple Labs

Well I would say all are “okay” options, but I would still prefer to build one on breadboard or stripboard.

Here are the list of all the projects whose heart is an IC555

1. Test your IC555 (tested)
2. Ambulance siren using IC555(tested)
3. Ic555 : Bird sound circuit(tested)
4. Factory Siren(tested)
5. Light to sound using IC555(tested)
6. Ic555:Magic eye(tested)
7. Metronome(tested)
8. Ic 555: Monostable multivibrator(tested)
9. Mosquito repellent circuit(tested)
10. Simple siren using IC555(tested)
11. Telephone Timer(untested)
12. Thermim(tested)
13. Touch based switch uisng IC555(tested)
14. Electronic organ-Resistance based(untested)
15. Electronic organ-Capacitance based(untested)

I would like to thank Arun Kumar R for his help, He is the one who tested most of the circuits, debugged and made those sirens sound like the original.
If you have and doupts you can mail it to me or Arun Kumar R

Well we know that a wide range of frequencies can be generated using IC555. Here we are implementing the same.Here we are changing the capacitance between PIN 6 and gnd (The capacitance directly added-up when connected parallely). There is a set of capacitors given in series , thus connecting the probe we will get different output.
