By
SMT Assembly Workshop

Learn to assemble and reflow solder a double sided SMT Arduino printed circuit board. At the end of this workshop you will have a working Arduino that you can take home. Note that every effort will be made to ensure you are successful but it is still possible to assembly the board in a way…

Eagle Routing Workshop

Step1 – Creating a layout from the schematic Open the “Road_Warrior” schematic. From the file menu select “switch to board” setup the placement grid by typing “grid mm” and “grid 1” in the command line. This sets the grid to a 1mm metric grid. You could also have used “grid inch” and “grid 0.1″ to…

Rolly Bot Preview

My first 3D printed Rolly Bot design is a work in progress. The printed plastic parts work well enough that I want to move on to designing a user friendly PCB as part of the design. As you can see in the photo of the yellow Rolly Bot the current UNO and wiring are a…

WS2812B Introduction

The WS2812B is a bit addressable RGB LED. The WS2812B (don’t confuse this with a WS2812 which has six pins) is a four pin device that is very simple to wire up to an Arduino. The LEDs can be daisy chained and are available as LED strips or discrete parts. Notice that no resistors are…

Carduino/Swarmbot

I’m not sure whether this design should be called Carduino or Swarmbot. The design of this car is based on the Arduino UNO where the pin map matches that of an UNO. The design includes a dual H-bridge so that the motors are individually reversible. I have also included an IR remote control to send…

Using Paper Car 2014

The Tiny84 paper car controller includes the following two features by default. First there is a motor speed controller which allows you to directly drive two low current motors. Using FET transistors attached to the Tiny84 I can drive two high current outputs. Typically the Tiny84 delivers 20mA of current while the FETs extend this…

Paper Blinky

Paper Blinky is a simple four LED circuit that allows you to develop Arduino code to turn the LEDs on and off in a variety of patterns. Rather than wiring the LEDs on a proto-board they are assembled on a permanent paper circuit; this allows you to rapidly plug in the circuit to demonstrate your…

By
Arduino Ottawa Contest #1

Our local Arduino Ottawa group created a design contest which required an Arduino design that uses a mystery component. The last day of the contest is June 10th so I had to get my project started quickly. To that end, I re-used as much of my paper car work as I could. This allowed me…
