i have an arduino uno and would like to plug an audio speaker (5W -not 0.5W- 8 ohm). would anyone have the kindness to tell me what resistor should i use for it? (and explain the calculation behind it so i won't bother again ;P) as a note i've already checked the "arduino tutorial tone". but got scared trying since the wattage of the speaker wasn't revealed...(or does it make sense or matter?)
My name is Alex from Switzerland. I am planning to start using Arduino on an artistic project due on this December... I have no experience in electronic but a bit in programming (python, processing).
Here are my goals: - create a vertical wooden panel with a button on it. the board has many holes that integrates LEDs (ideally white and around 50 of them) - create a sound device connected to the board - write the program for 2 states: when nothing happens then light pattern 0 + sound 0, once the button is hit then light pattern 1 + sound 1, once the pattern 1 is done back to 0.
"That's it" i guess. So if anyone has the kindness to guide me i would really appreciate. I don't really know where to start but here are already some questions: - what kind of Arduino board should i get for this? - what are the other devices/components i need to make this work and where's the best place to buy them ? (piezo, amp, button, LEDS, cables...) - about the LEDs how to connect them to a breadboard if they are at a greater distance ( bare in mind that i don't know how to solder...)
Big thanks in advance! Reading back myself i feel November will vanish in a sec
