The dreaded ‘LED Fan-Effect’. Due to size, it’s impossible to fit round LEDs neatly in the same breadboard row. Round LEDs are SO last season...introducing new rectangular LEDs!

Throughout my development of Stamps in Class Mini Projects and training of teachers and students, I've had one constant pet peeve: the LED Fan-Effect.

The "LED Fan-Effect" occurs when attempting to line up three or more T 1-3/4 circular LEDs in the same breadboard row. The diameter of each of these LEDs is too wide to fit neatly and as a result the LEDs splay across the breadboard. The result is messy and displeasing to the eye, yet unavoidable.

Arlo platforms in the workshop Arlo Power Distribution Board for the Arlo Robotic Platform System is Heading to Kitting!

In a prior post, I demonstrated how you can use our ActivityBot C code in our big Arlo platform to quickly and quietly carry loads and also apply classroom robotics for real applications. Imagine having a robot that can drive between your class and the office, one to launch fireworks at sporting events, or carry your computer and smaller robots along for you.

Until today, wiring for any of these was a bit of a time-... More
