Can i remove the ic,(at mega 328) after program using arduino and place it in the same circuit.whether it work properly.
For the blink led example in the IDE, pin no:13 is the led pin.If we remove that ic from the arduino board and place it individuly pin no:13 is marked as PD7 in the pi diagram of atmega 328.is it work properly?
You can remove the ATmega328P-PU chip from the Arduino board and provide it with power (3.78V to 6V), ground, and a 16 MHz crystal or resonator to make the sketch run. Pin 13 of the Arduino is connected to pin 19 of the chip so that is where you would connect an LED and resistor to watch the LED blink.
It seems a lot of the tutorials on this here on this site are outdated (links don't work, pics aren't appearing).
Are there any other good sites for this info? As in, beyond the crystal and 328p chip, what else does one need to do? Should I have caps on the crystal like gammon's site says?
Parts you should have - 10K resistor from Reset pin to Vcc (+5V)
VCC connected to AVCC
0.1uF cap from Vcc pin to Gnd
0.1uF cap from AVcc pin to Gnd
0.1uF cap from Aref pin to Gnd
Resistor between Pin 19 (PB5, SCK, same as onboard LED) to LED anode, LED cathode to Gnd,.
Crystal between XTAL1 and XTAL2 pins
22pF cap from XTAL1 pin to Gnd.
22pF cap from XTAL2 pin to Gnd.
4.5V (3 AA batteries) or 5V (regulated DC output wallwart) for power, connect to Vcc/Avcc pins.
I'm sure I posted a similar picture last night.
FTDI and ICSP headers are optional.
Diode is optional.
0.1uF cap between FTDI DTR pin and reset is needed for autoreset during software download if using an FTDI Basic for serial interface to a PC.
