I'm extremely new to arduino. I originally bought my uno micro controller to find a way to remotely detonate fireworks. The initial basic model for my detonator would be this:
Following the instructions listed here(http://projects.sindrelindstad.com/how-to-led-arduino-php-proc/
), I have set up a web site with an on/off switch.
The arduino would be connected, by nichrome wire, to a battery with a high voltage. The battery would be connected to the firework by nichrome wire too.
I wish, when the switch on the website is turned 'on', for the website to turn the arduino on. This would send a message to complete the electrical circuit and to detonate the fireworks.
Question 1: can an arduino be used to turn an electrical circuit on and off?
Question 2: can nichrome wire be connected to an arduino in the way illustrated above?
Question 3: how can the Processing IDE script be altered to complete the circuit instead of turning on an LED?
Question 4: is the procedure explained above possible and feasible?
Thank you very much for taking the time to answer my questions.
