rorosol_cover

Bletooth soldering station with Arduino

Building a soldering station is not that hard if you have a Arduino at hand. But I wanted my station to be small and to have something extra than just a temperature controller. This is how I come up with roroSOL, the bluetooth soldering station with arduino.

 Needed components

  • Arduino Mini Pro
  • HM-05 bluetooth module
  • LM358N operational amplifier
  • 5v+ logic MOSFET
  • 2pcs-10k,1pc-1k, 1pc-120k resistors
  • 2pcs-0.1uF capacitors
  • cheap soldering iron
  • 24V (aprox. 6A) power source

SMSAlarm-titlu

SMS alarm system with Arduino

This project represents a simple SMS alarm system made with Arduino that allows you to arm or disarm via SMS message. Also when the alarm is triggered you’ll get a SMS notifying you that. And because I know that is very hard to type messages the included android app will help your fingers to rest 😀

 Needed components

  • Arduino Uno
  • A-GSM shield
  • Bread board or prefboard
  • laser diode
  • photoresitor(LDR)
  • 10k resistor
  • leds
  • wires for connections

Cum sa arzi un Arduino Pro mini in 3 pasi simpli

 

1.Se ia un arduino pro mini

2.Se alimenteaza pe pinul RAW cu 12V 6A

3.Bucurati-va de artificii!!!!!!

La urmatorul link gasiti mai multe detalii despre ce s-a intamplat: http://electronics.stackexchange.com/a/18479

Sugestii ca sa evitati aceasta problema:

  1. Nu alimentati direct cu 12V 6 A
  2. Folosire radiator
  3. Folositi un regulator auxiliar 12V-5V, de preferabi ceva diferit de L7805
