Paperduino: How to Print a Paper Arduino. Shrinkify Your Arduino Projects. Ever since I started making projects with the Arduino, I’ve had a desire to shrink them down to a single, small circuit board. One of my first projects, a customizable SLR intervalometer, was packed in a phonebook-sized cardboard box and used the Arduino Deumilanove connected to a breadboard with jumper wires.
I brought the box out to Central Park at 5am to make a timelapse of the sunrise, but when I got to the park, I spent 20 minutes fixing the connections between the Arduino, the breadboard, and the components. Since then, I’ve explored a few different ways of shrinking projects down and making them more robust.
For the intervalometer, I designed a circuit board that had female header pins to seat an Arduino Nano. It was a huge improvement on the design, but I knew I could do a lot better. I tried to teach myself AVR programming, but ran into a lot of snags along the way. When I came across this tutorial by MIT Media Lab’s High-Low Tech Group, I was elated. More: Matt Richardson.

Jan 2009 - New library with M3 and M4 speed swap fixed.Ugh! Also tested with up to IDE 13 so should be fewer problems Watch out! On some (much) older boards, Ground and VCC are swapped on the silkscreen next to the analog pins! The silkscreen should be "+5, GND, A0-5". Use a multimeter to check if you're confused Motors need a lot of energy, especially cheap motors since they're less efficient. Current requirements: The second thing to figure out is how much current your motor will need. On using the SN754410: Some people use the SN754410 motor driver chip because it is pin-compatible, has output diodes and can provide 1A per motor, 2A peak. Need more power? You can't run motors off of a 9V battery so don't even waste your time/batteries!
Servos are powered off of the same regulated 5V that the Arduino uses. The DC motors are powered off of a 'high voltage supply' and NOT the regulated 5V. There are two places you can get your motor 'high voltage supply' from. Here's how it works: Arduino electronics and robotics. Make an Arduino into ISP programmer. The Arduino and Arduino compatible boards all use a small program called a bootloader to take serial data from your computer and store it in the Arduino's memory. You will need to "burn" the bootloader into the chip if: You are building your own board and have bought a blank chip.Your 5V rail dropped too low for too long and your bootloader was corrupted (perhaps due to flat batteries).You overwrote your bootloader at some time to save memory.
Fortunately The Arduino IDE includes a program called "ArduinoISP" that allows you to use one Arduino board as a programmer to burn the bootloader into another board (the target). Using the latest versions of the Arduino IDE (V1.0 or later) you can write your code directly to the MCU without using the bootloader. PLEASE NOTE: This tutorial was written using Arduino 1.02 which was the latest at the time. I normally use an Arduino Nano as a programmer because of it's small size. 3x 4K7 resistors.1x diode (1N4001 or 1N4148).
