Questions regarding multiplexing a common anode RGB led matrix

so, acquired rgb led matrix  ,because i'm new electronics, don't know stuff should. i'm planning on driving board using 4 74hc595 shift registers , arduino uno (later on i' ll try switch arduino nano) my questions are: what resistor value guys suggest use drive each set of colors? if rgb led matrix has different values red blue, should use different resistor value? i planning on using 5v power supply (the arduino's) can use 9v, 1 should use? i have attached datasheet of matrix ( here is link too). if more information needed please let me know, thanks! if use 595 registers drive matrix have use high value series resistors avoid overloading pins connected anodes. mean matrix dim , perhaps visible in dark room. each pin on 595 can source maximum of 35ma 1 of matrix anodes. them have shared between 8 red, 8 green , 8 blue leds, 24 in total, 1.5ma each. 1 in 8 multiplex, leds receive 0.2ma on average 1%of leds maximum current. so oth...

Detecting if person walks into/out of room using IR sensor?

i'm new programming/arduinos, i'm trying make tell me when walks or out of room using ir sensor. preferably, arudino connect computer in different room using bluetooth. can me started? an ir sensor might wrong choice; need 2 can determine direction. maybe can consider hc-sr04; can measure distance , based on changing distance determine direction.

XP patch for Firewire camcorder connection

Alimentation externe pour Shield

bonjour tous, dans ce topic j'aurais besoin de conseils en rapport avec l'arduino mais aussi en électronique : le projet : a partir d'un shield de prototypage j'ai réuni un panel de composants pour faire un shield personnel et modulaire : bmp280, blutooth, gsm, oled 0.96, gps... les modules se branchent et se débranchent au gré des mes envies sur des pins que j'ai moi même disposé...  le soucis: parmi les modules j'ai le fameux sim800l qui doit être alimenté en 3.7-4.2v et peut consommer des pics jusqu'à 2a (l'arduino donne soit du 3.3 ou du 5v mais pas prévu pour 2a) donc je souhaiterais mettre une entrée sur mon shield pour une alimentation externe capable de fournir 2a via un bornier à visser (la source de l'alimentation n'est pas le problème) et quit mettre une alim sur le shield pourquoi pas la partager avec l'arduino  les problèmes : fournir une alim au shield et aux modules fournir une alim l'arduino fourni...

(so the rpi 5v level may problem.) the gpio pins connected directly if both boards 5v or both 3.3v boards.  if boards supplied different voltages level shifter required.  pullup resistors (4.7k ohm sda vcc , scl vcc) required i2c buss work.
