LoL shield proves that you can’t have too many LEDs
One fine morning, Jimmie P Rogers woke up and decided to figure out how many Charlieplexed LEDs would fit on an Arduino shield.
Arduino
As the preeminent tool for makers, Arduino is a versatile platform that covers almost every type of creative making. With its simple-to-use coding language and fun programming concepts, Arduino enables users to create modern electronics with ease. From beginner level projects like flashing LED lights to more advanced builds such as interactive robots, there are an endless number of possibilities when it comes to building projects with Arduino. Whether you are new or an experienced builder in search of fresh ideas, these posts will provide interesting Arduino tutorials and unique ideas that may spark your creativity and motivate you take on any type of maker project!
Simavr, an AVR microcontroller simulator
Enjoy programming AVR microcontrollers, but wish there was a better way to debug your programs then blinking lights?
How-to: Using a 555 timer as an external clock for the Arduino
Here is another how-to from Jeff, this time he describes using a 555 timer as an external clock for the Arduino. It’s a really interesting technique on how to get a fairly accurate external interrupt at lower frequencies.
Multiple Peggy2s displaying serial video
Ian from weezey.com wired up a couple of Peggy2 light emitting pegboard kits to an Arduino and with a couple of tweaks to some existing code managed to get the display to run across both units.
In the Maker Shed: Advanced Arduino Starter Kit
Bridging the gap between the “real world” and your computer, the Advanced Arduino Starter Kit from the Maker Shed takes you further into the world of physical computing.
How-to: Connecting a 7-segment LED to the Arduino
Jeff posted this nice how-to about wiring up a 7-Segment LED to an Arduino. His code uses the ‘map()’ function to scale the sensor data and display it’s relative value on the 7-Segment display.
Solarbotics Ardweeny
Our finely-wired friends at Solarbotics have released their latest Arduino kit, the Ardweeny, “the smallest Arduino you can build yourself with through-hole components.” I love the backpack PCB concept which puts the support electronics for the ATmega328 chip on a board that stacks on top of the chip and is soldered to the chip’s pins.
