SUMMARY
The MintDuino is perfect for anyone interested in learning (or teaching) the fundamentals of how microcontrollers work. It will have you building your own microcontroller from scratch on a breadboard, and then easilyprogramming it from almost any computer via the Arduino programming environment. Unlike pre-built microcontrollers, the MintDuino demonstrates the specific relationship between the wires, resistors, capacitors, and integrated circuits that enables you to program the microcontroller from your computer. After building the MintDuino, you'll have a much better understanding of how microcontrollers work, andhow electronics can interact with the physical world.

Step 1 — Build a Mintronics: MintDuino
Start building your MintDuino by adding the 7805 power regulator. This converts the 9v power to 5v power that the ATMega can use. Insert the 7805 into column "i" on the breadboard and rows 1,2 & 3 as pictured.The metal heatsink should be facing the right (or column "J")

Step 2

Now we are going to add one 10 uF capacitor to the power regulator. I like to trim the leads down so it doesn't stick so far out of the breadboard. One lead is longer than the other. The long lead is the (+) lead and the short one is the (-) lead. If you trim it, make sure to keep the lengths different lengths so it's easyto identify the (+) and (-) leads. Insert the (+) lead into "g1" & the negative lead into "g2". Easy!

Step 3
Next is the other 10 uF capacitor that we use to smooth out the power on the breadboard. Insert the (-) lead into row 1 of the (-) power rail of the breadboard. Insert the (+) lead into row 1 ofthe (+) rail of the breadboard as pictured.

Step 4

Now let's get some regulated power over to the power rails of the breadboard. Start by stripping the ends of one piece of red wire cut to approximately 1/2" long. Insert the wire from the (+) rail of the breadboard to "j3" of the breadboard. Next strip the ends of one piece of black wire cut to approximately 1/2" long. Insert the wire fromthe (-) rail of the breadboard to "j2" of the breadboard as pictured.

Step 5

Now we are going to add the power LED (Red). Start by cutting down the leads, as we did on the capacitor. Make sure to keep the long one (+), long, and the short one (-), short! Now you can insert the red LED into thebreadboard. The longer lead (+) goes into "d2" and the negative (-) goes into "d1"

Step 6

Let's get the power distributed around the board and to the LED. Start by cutting one red wire, approximately 1/2" long and one black wire, approximately 1/2" long. Strip both ends of each wire. Insert the red wire from "f1" to "e4", and the black wire from "f2" to "e5". Cut another piece of black wire about1/2" long (I'm going to stop saying "strip each end" each time) and insert it from the (-) rail of the breadboard (picture 2) and "b1" While we are here, lets add a 220Ω resistor (red, red, brown) from the (+) rail of the breadboard to "b2". Lastly, cut one piece each of red and black wire about 1 1/2" long and connect the right side rails together. Remember to connect (+) to (+) and (-) to (-) asin picture 3.

Step 7

Power it up! Now connect the battery clip's red wire (+) to "d4" and the black wire (-) to "d5". Connect a 9v battery and the red LED should light up. If not, immediately unplug the power and double check everything!!! Now you have a nice 5V regulated power supply from a 9V...
