A small story about Blinker using arduino and NE555 timer IC

A small story about electronic components NE555

This is the one of the easiest arduino projects. You might be interested in making this project on breadboard. So, you can take some easy steps given below:

- One pin of reset switch goes to GND(ground) and the other pin goes to reset pin(Pin1 of chip).
- 10K resistor is connected across reset pin (Pin 1) and Vcc. Vcc is the power to run the programmer and that is drawn by FT232RL breakout board via computer.

- Pin 7 of chip goes to Vcc
- Pin 8 of chip goes to GND
- 16Mhz crystal oscillator is connected between Pin 9 and 10 of Atmega chip.
- One 22pF capacitor is connected across pin 9 and GND and the other capacitor across Pin 10 and GND.
- Pin 22 goes to GND
- Pin 20 and 21 go to Vcc.
- 330R resistor is connected to Pin 19 (DIG 13) and cathode terminal of LED and the led’s anode terminal is finally connected to GND.

Many hot ic components lm358,lm317,lm339 and so on, high demand in the market.
