Starter Kit Recommendations + ATMEGA328P-AU vs. ATMEGA328P-PU

-

hello, all!

alright, i'm 100% new arduino , designing electronics in general. programming, couple years ago took couple of programming classes (c++ , java), @ point have forgotten everything.

i'm looking complete starter kit possible, low price possible. i'm living on stipend (student missionary), budget is, @ most, $50 (can go higher if necessary, demonstrated ~$60 price tag of kit linked below).

as such, looking @ clones. i've been looking @ ebay @ of cheap kits china, , liking i'm seeing in terms of price/component ratio.

one kit ran across has components i'm looking (i'm envisioning various ideas of projects use ultrasonic distance sensors, sound sensors, lcd displays, rfid, relay modules, , motion sensors... possibly accelerometers well, unfortunately kit doesn't have one), i'm wondering arduino clone comes with... it's called infiduino uno r3. claim complete compatibility arduino uno r3, take mean work shields , stuff well. 1 thing i'm concerned it, though, whether there functional differences i, newbie, run between atmega328p-au (the 1 on infiduino) vs. atmega328p-pu.

here link package:
http://www.ebay.com/itm/full-edition-uno-r3-starter-kit-for-arduino-1602lcd-servo-motor-relay-adapter-/221503487021?pt=lh_defaultdomain_0&hash=item3392a2fc2d

and here link infiduino page:
http://wiki.epalsite.com/index.php?title=infiduino_uno_r3

any other kits recommend similar price?

another question have: relay modules able used wall outlet? there's 1 listed in kit, unfortunately not give part number or check on it.

thanks!
electropulse

same die inside, different physical package.
wallwart needs 7.5v, 9v, 12v plug barrel adapter.
or 5v usb cable plug usb connector.

look @ kits www.yourduino.com also, terry king offers student discounts well.

hello, first post asking in forum patient if dont correctly   well, im trying make robot evades obstacles , uses interrupts in order distances. ive used flexitimer2 run void function each 5ms, problem whe try verify program says me there error in use of flexitimer.    code: [select] flexitimer2::set(1, 1.0/1000, rastreodistanciamin()); i copy code below, please can tell error , how solve it, ive been loking dont know do. thank you code: [select] #include <flexitimer2.h> #include <servo.h> //motor a int ena = 7; int in1=6; int in2 = 5; //motor b int in3=11; int in4=10; int enb=9; servo cabeza; //hc-sr04 device int echo = 13; int triger = 12; //it use hc-sr04 determine , return distance in front of him int calculodistancia(){   volatile int tiempo;   volatile int distancia;   digitalwrite(triger,low); /* por cuestión de estabilización del sensor*/   delaymicroseconds(5);   digitalwrite(triger, high); /* envío del pulso ultrasónico*/   delaymicroseconds(10);   tiem

LED Strip Code

i downloaded code. here have several single leds flashing music microphone. in project, instead of single rgb leds, have 5 rgb led strips. need change in code? led strip 10m supernight rgb strip cut 5 equal strips. // arduino pin numbers const int do_pin = 2; const int ao_pin = 0; int sound; int led1 = 8; int led2 = 9; int led3 = 10; int led4 = 11; int led5 = 12;   void setup() {   pinmode(do_pin, input);   pinmode(led1, output);   pinmode(led2, output);   pinmode(led3, output);   pinmode(led4, output);   pinmode(led5, output);   serial.begin(9600); }   void loop() {     if (sound > 31) {     digitalwrite(led1, high);   }     if (sound < 31) {     digitalwrite(led1, low);   }     if (sound > 35) {     digitalwrite(led2, high);   }     if (sound < 35) {     digitalwrite(led2, low);   }     if (sound > 40) {     digitalwrite(led3, high);   }     if (sound < 40) {     digitalwrite(led3, low);   }     if (sound > 45) {     digitalwrite(led4, high);   }     if
