286  Using Arduino / Microcontrollers / What does the -PU, 16PU means ? on: October 25, 2012, 11:54:12 am
Hey guys, I have a very simple question here :

I saw that in Atmega 8, stated there is like Atmega8-16PU, and for Atmega 328 is like Atmega 328-PU, so what does the PU means actually ?

Thank you

This one ?

The FT Txd and Rxd connect to the Atmega Rxd and Txd. Look at the arrows on the chip to see the direction of the signals.

The left side of C5 goes to Reset. I would compare this against an Arduino schematic as well.

What is the thing in 500mA ?? Curious

So, just this 3 pins is connected to the atmega ? Excluded the VCC and GND to chip

So the bottom left ( DTR, TXD and RXD is connected to the atmega ? connect to which pin of atmega ?

Thank you

Erm, is that we just connect CCC, gnd, txd and rxd to the avr chip?

Hey guys, recently I just bought a FT232RL chip from RS. So, I would like to ask, how can I connect that to my AVR chip so that I can program my AVR chip just through the USB cable ?

Any schematic ?

Thank you

I have one atmega 8
now I want program it using arduino IDE
I didnt burn bootloader in it
so how can I program it using arduino IDE ?
Any changes I need to make to the arduino IDE ?

Means I various with the light intensity. Hahahaha..

Explain why the light intensity of the LED will affected by the intensity of light o LDR. I suppose it to be either HIGH or LOW...no intermediate. But when I vary the light intensity, the LED light up abit and when totally <400, the LED is fully light up

Erm, sorry .. My code is <400..Typo..

So how to explain the thing ?

Hey, according to this coding, this is a night lamp circuit. So I am curious about one thing. LDR is an analog sensor. So, the light intensity of the LED at pin 13 will change according to the light intensity received by the LDR. But then according to this coding, it is either a sharp 5V HIGH for the LED at pin 13 or a LOW for the LED. If the sensovalue is <150, which means dark ,so the LED will light up with 5V. But when I play with it, the light intensity of the LED is various with the LDR. So this make me do not understand fully about the coding @@ Can anyone clarify for me ?

Means I am correct ?
298  Using Arduino / Microcontrollers / Re: Bootloaing AVR chip on: September 05, 2012, 11:48:59 pm
Can you elaborate more on that ?

Thank you smiley
299  Using Arduino / Microcontrollers / Re: Bootloaing AVR chip on: September 05, 2012, 11:35:53 pm
Anyway, thanks for your great help in providing info smiley

I am still very blur about it. When burning bootloader, I have to change the setting..but when uploading code, Atmega 328 is the same as Atmega 328P ? So that is why the bootloader for atmega 328 lies ? Because the IDE recognise only Atmega328P bootloader ?
