Get the RGB SunLight
Prepare your smart Light's brain (bend the Atmega pins)
This step is optional, but may make it easier to insert the atmega168 into the PCB. Use a ruler, or a stapler or anything small, flat, and strong to bend the atmega's pins so that the two sets of legs are little closer together. In the picture I'm using a piece of plexiglass (stay lucid!).
Insert the Atmega168 in the Correct Orientation
The atmega168 must be inserted so that pin 1 lines up with the pin labelled 1 on the sun-shaped PCB. Pin 1 on the atmega (like on all DIP packages) is the one directly to the left of the U-shaped depression. Make sure you have same orientation as shown in the picture.
Insert the LM386 Audio Amplifier in the Correct Orientation
The LM386 is the smaller chip with 8 legs. You may want to bend its legs together before inserting, like you did with the Atmega168. Again be sure to line pin 1 on the LM386 with the silkscreen 1 on the PCB. Use the picture as a guide.
Add the Crystal and the 2n3904 NPN Transistors
Now insert the 16MHz oval-shaped, silver, crystal oscillator. The orientation of the crystal does not matter. Also insert the 3 2n3904 NPN transistors. These are the black semi-circular silicon transistors which have 3 legs. The orientation of the transistors DOES matter. Insert them so that their semi-circular bodies follow the white silkscreened outline of their shape on the PCB.
Insert the RGB LED
Now after soldering down the chips, transistors and crystal, you are ready to start inserting the RGB LEDs. Again orientation matters, you must insert the RGB LED so that its longest leg (the common cathode pin) is closer to the flat side of the silkscreen led shape on the PCB. Use the image as a guide.
RGB LED Correctly Inserted
Make sure your LEDs are in the orientation shown in the picture.
Insert All the RGB LEDs
Now insert all the RGB LEDs, with each one being careful to insert it in the correct orientation. Long leg one pin away from the flat edge of the LED outline.
Insert the 10K and 10 ohm Resistors
Once you've soldered the LEDs down and chopped off their legs with your cutting pliers, you are ready to start putting in the resistors. First grab the 10K ohm resistors the ones whose color bands go brown-black-orange-gold. Insert them in each of the resistor placeholders labelled 10K. You should also have one 10 ohm resistor with color bands brown-black-black-gold. Insert this one in the slot labelled 10 near the LM386 chip.
Insert the 300 ohm Resistors
The kit comes with fifteen 300 ohm resistors, these protect the RGB LEDs from too much current. Insert all 15 in the resistor slots labelled 300 on the opposite side of each of the RGB LEDs. Don't worry about the orientation the resistors are symmetric.
Insert the Buttons
Now insert the two buttons. They go on two of the sun's flames that don't have LEDs on them.
Now insert the potentiometer (the five legged knob) in its correct place on the sun PCB.
Insert the Electret Microphone and the On/Off Switch
Almost Done! Now insert the Electret microphone. The ground pin on the Electret Mic is the pin connected to metal shield this pin should go in the pad labelled with a minus sign on the PCB. If the circle outline fits snugly around the mic then you did it right. Also put in the black three-legged on/off switch.
Lastly insert the USB connector if you want to power you SunLight from a USB cord otherwise you can attach a battery pack to the pins labelled 5V and GND. Power you're badboy up and get ready for Rainbows!
