123D Circuits Video Series : Servo and More!

123D Circuits Banner

Ready to get your How-To on?  We've recorded a handful of awesome new videos that teach basic and advanced concepts of electronics in 123D Circuits.  Each video is based on an existing circuit and with one click you can duplicate it, learn from it, and build it into bigger and better projects.  

Circuit: Arduino and Servo


Circuit: Potentiometer


Circuit: Blink LED with an Arduino


Circuit: Oscilloscope Basics

Light Tracking BEAM Robot Comes To Life

Last week we announced a new theme: ROCKETS and ROBOTS so I'm super excited to post about a BEAM ROBOT that we've given life in 123D Circuits

"BEAM" is an acronym for Biology, Electronics, Aesthetics, and Mechanics.  It refers to a style of robots that don't require programming - instead they use analog logic to react to stimulus of various types (like light, sound, and heat).  The great thing about BEAM robots is that you can learn a lot about electronics just by making one or even taking one apart.  To get an idea, check out this BEAM robot simulator in 123D Circuits and experiment by clicking on its components to see what happens.

There are a ton of BEAM robot-related Instructables and we chose to build a simulation of one that reacts to light.  This is called a Phototrope, as it will try to move toward a light source.  That's pretty buggy!

Below is the simulation of the left 1/2 of the BEAM robot.  For clarity, we've linked a simulation of just one side of the BEAM robot (the second half would be identical).  Full left-right schematic here.

Whats What

We’ll be releasing this as a finished circuit board so you can build one, too.  We're also working on a 3D model for an enclosure in Tinkercad that you can use or build off and make your own Phototrope Bug.  Stay tuned!
