…………………………………………………………………………………………………
Parts:
Arduino (any board)
Jumper wires
RF remote and receiver
5-9volt power supply (for Arduino)
5volt 4 channel relay module
12volt 2Amp ISOALATED transformer
Wire (Needs to handle 5 Amps)
Nichrome wire (from a hair dryer for example)
Alligator clips
Project box (5x10cm/2x4in) (Optional)
Tools:
Wire stripers
Wire cutters
Screw driver
Hot glue gun
Step 1: Wiring Up
-----------------------------------------------------------------------------------
Arduino:
.....................................
relay:
Vcc to 5v
GND to ' - ' / Ground
Pin 13 to relay 1
Pin 12 to relay 2
Pin 11 to relay 3
Pin 10 to relay 4
.....................................
receiver:
Vcc to 5v (unless it runs on 3.3v)
GND to ' - ' /ground
Output (any button pin) to Arduino's pin 2
....................................
---------------------------------------------------------------------------------------
12v transformer
One wire (any one) spit to one side of each bit of nichrome wire and
the other wire split to each relay connected to 'COM' port,
last but not least a bit of wire from 'NO' port of the relay to the other side of the nichrome wire. you will need to take the cover off each clip.
----------------------------------------------------------------------------------------
Power supply
5-9v power supply to Arduino power in barrel jack.
Step 2: Uploading the Code
Plug in your arduino, select type of arduino: tools-board-_____ and com port: tools- serial port-________
finally upload the code ctrl-u

Step 3: Housing (Optional )
For this step you can mount everything inside how you want.
Step 1:
Drill four holes on the long side and on the Opposite side drill two holes along with holes on the bottom to mount the 12v transformer.
Step 2:
Glue a piece card board to the bottom of the box on one side, this is If it is a metal box and prevents short circuiting to the metal.
Step 3:
Attach the Arduino, relays and RF receiver to the card board.
Step 4:
Mount the 12v transformer with screws and nuts.
Step 4: Set Up
Step 1:
Place the firework in a secure spot, but make sure the other fireworks are at least 30cm/11inch apart.
Step 2:
Place the control box and 12v transformer next to the firework at least 50cm/19inch away. Plug the 5-9v & 12v transformer (you may need to use an extension lead and a plug board).
Step 3:
Wrap 2.5cm/1inch of nichrome wire around the fireworks fuse.
Step 4:
Attach the alligator clips on to each bit of nichrome wire.
Step 5:
Make sure you have a Co2 fire extinguisher near by, DO NOT USE WATER with electrical nearby!
Step 5: Before You Press the Button....
