  1. the 1 kohm resistor is needed between Arduino TX and DFPlayer RX because the serial input is goign at 3.3 volts while arduino otuput is 5 volts. " 4.1 Serial Communication Connect Module's serial port is 3.3V TTL level, so the default interface level is 3.3V. If the MCU system is 5V. It is recommended connect a 1K resistor in series" http://www.picaxe.com/docs/spe033.pdf btw great work!
  2. just send me a PM and i will send you the link with the zip file to download (sent you) IMPORTANT NOTE ABOUT THE PROJECT: i fixed the RESISTOR value between the MP3 Player (DF Player) and Arduino, it must be 1 KOHM instead of 10KOHM or the DF player (and clones) wont work fine or at all!
  3. that sounds great, i just ordered the MAX4466 over ebay i think it can go even with 3 AA alkaline batteries
  4. it's working great! the MAX4466 preamp microphone is very reliable
  5. Notes about the DFplayer sound module: you can find several DFplayer chinese clones on the market but not everyone fit this project. In fact there are fakes clones that don't support the DFplayer libraries. working clones have a chip named "YX5200", blue led status light, silkscreen around all components on board.. example of not working clone:
  6. just note i made an easy assembly board to make the work easier and better. Just succesfully completed its testing, the sound is loud and clear, no clipping or noise, thanks to PCB connections. With this board it will be easier to fit arduino and their components inside the PVC pipe, saves extra cables and work, no mistakes. Size WxLxH mm main unit: 91x29x21.8 drivers module: 41.5x29x18.70 bar leds module: 35.5x19.5x9.85
  7. that was a good find, by the way these sounds are streamed at 22.050 kHz / 16 bit because of the limitation of their board. In this project you can play MP3 files at 44.100 kHz (and over), that is much better quality. This is because here the limit is just the SD capacity (up 32GB!). For example, you can upload the best soundtracks from the saga or any background sounds (like the stormtrooper chatting radio from 501forum), playing them while your blaster is folded. If you need the mp3 sounds just send me a pm, i will send you the link and the password.
  8. just in case, i update the range limit of the power supply of the latest scheme with arduino pro mini, from 7,4v - 12v into 7,4v - 9v after some testing and reading around, i realized that these arduino pro mini chinese clones can't handle in this project 12 volts, it will burn their small voltage regulators. By the way, it is really unecessary 12 volts, the project just need around 7,4volts
  9. great job! i like the idea of the transparent rod to light up the bar
  10. you are right The voltage regulator should be positive i used the L7805CV edited first page
  11. sure and it would be very easy it might be better to start a new code with the basic functions fire sound and led light when fire
  12. Ops didnt know of double barrel. If they fire at the same time you might try to use 3 drivers of 700mA for both RGB Leds, the PWM control from arduino should works for both. In that case the 2 RGB leds should be connected between them in parallel to double the amperage needed. Otherwise you still need the 350mA for each color with pt4115 and pwm output.
  13. please when you post in this topic add more specific information how to add that feature in this project, such as the updated scheme, the link of the module (datasheet), otherwise is quite unuseful. Thanks.
  14. not sure what leds you are going to use as fire effect, are you going to use an RGB led or standards led as in the video? or you want to use 2 sets of RGB led? why should you need 2 in that case? drivers are needed in the RGB led because high amperage. In that case you need a 350mA driver for each color. But if you use standard led as the second picture (they rated about 20ma) you don-t need the driver, you can use a resistor as the blue pulse led (around 100ohm).
