First project, what components do I need? (Temp controlled fan)

hi, first post here. i don't yet have arduino board or parts thinking of buying starter kit alternatively parts needed project below. i understand basic programming concepts not electricity. however, learn doing things. the purpose of post choosing suitable arduino board suitable components project below. no need advice me on programming part yet, plan learn use , program when components. what have: -a 3d-printer custom built enclosure (to prevent drafts , increase ambient temperature). -a 12v pwm computer fan mounted through wall. (http://noctua.at/en/nf-f12-industrialppc-2000-pwm/specification) what want do: -read temp inside enclosure -increase fan speed proportional temp -change target temp cycling through 3 pre-set settings, (for example 25°/35°/45°) using simple button. (note not want set target temp via manual input rather have 3 profiles change between. match ambient temperature 3d-printing filament) -display temp on 1 line of lcd , chosen profile on second line -...

Matlab Arduino transfert d'une variable.

bonjour, je rencontre un petit problème dans l'élaboration de mon projet c'est pourquoi je viens vers vous. je reçoit des données via mon module nrf24l01+ ( réception rf) provenant d'une autre carte arduino. ces données sont celle d'un imu gy-521. elles sont donc composé de 12 octets et je les stocke dans 6 variables différentes. mon problème est qu'il faut que je transfert ces variables sous matlab. j'ai donc installé le package support arduino pour matlab. j'arrive ainsi allumé éteindre une led depuis matlab. ma question et comment faire pour transférer ma variable disons "toto" stocker dans mon micro controleur vers matlab? j'ai peur que en utilisant matlab cela téléverse un nouveau programme dans mon arduino venant écraser l'ancien. vos lumières m'éclaireraient bien, merci d'avance pour vos réponses. vous pouvez lire cela en gros vous configurez matlab pour lire ce qui vient sur le port série et cô...

i have been using uno , 101 without problems. have micro 5v board , cannot sketch run when using external power via 9v battery micro usb connection. im trying blink example now, works fine when connected computer via usb hook battery stops working.. . please help. that's because supply usb 5 volts not 9 volts (ouch) maybe connect little lower voltage if going direct usb connector or use proper vin pin. pinout here   Arduino Forum > Using Arduino > Installation & Troubleshooting > Help needed with Arduino Micro board arduino

Thread: Trying to get backlight to work with psb driver on netbook

hi, bought msi x260 ultra light (netbook) , far working pretty good, however, can't adjust backlight batterlife worse be. have installed psb driver (poulsbo) per https://wiki.ubuntu.com/hardwaresupp...ocardspoulsbo/ , works fine except backlight adjustment. dug deeper , downloaded psb-kernel-source , looking through source. interesting found code in intel_lvds.c checks see blc_type when module loaded. throughout code manipulates backlight, code checks see if blc_type either 0x01 or 0x02 , acts accordingly, however, blc_type 0x00, why don't have backlight support. 2 possible blc_types defined #define blc_i2c_tpe 0x01 #define blc_pwm_type 0x02 . don't know means. have idea how backlight working? xrandr --ouput lvds0 --set backlight 50 not work me. hey, did ever find solution? guess 1 try force setting 0x01 or 0x02, of course risky. assume have no files in /sys/c...
