123D Circuits Video Series : Measure Voltage

123D Circuits Banner

In continuing our new video series on Electronics we're hoping you walk away from this tutorial knowing how to measure voltages in real life and in the 123D Circuits virtual circuit simulator.  You may follow along with the video, or just watch and be entertained.
This link will take you to the playlist of all videos 


In this video we're still keeping it simple by getting the main point across in under two minutes.  If you watch all 7 minutes you may even learn some engineering science!  Check out the video below.

123D Circuits is a fantastic place to go to build electronic circuits without leaving your computer.  It's as simple as dragging together components and watching them come alive in your web browser.  It's fast, it's free, and it's quite powerful.


You can do this yourself, just head over to 123D Circuits and sign in, then create a "New Breadboard Circuit" then follow along with the video.  You never know, this could be the beginning of something big - we think so!

 

 

123D Circuits Video Series : Light an LED

Update: This is the first video in a series where we teach electronics through simple, short videos using 123D Circuits.  You may follow along with the video, or just watch and be entertained by the nerdy voice-over.  This link will take you to the playlist of all videos.


In this first video we're starting with the very basics: how a breadboard works and how to use one to connect an LED to a battery with a resistor and one wire.  Check out the video!

123D Circuits adds Arduino MICRO and ATTINY

For almost a year now you’ve been able to simulate a virtual Arduino UNO in 123D Circuits and in that time tens of thousands of people have used an Arduino board in their virtual breadboard projects.


Today we're announce two Arduino components new to 123D Circuits:  The MICRO and the ATTINY!

Having these two new components is valuable for a few reasons:

The first is that you may want to design your projects with components that are a lot smaller than an UNO and fit on a breadboard.  Your projects will look cleaner, use less wires, and if you’re also building a physical project using the smaller MICRO or ATTINY you’ll save some money over the bigger UNO.


ATTINY graphic 220 pixels wideSecondly, if you think about it the ATTINY isn’t really an Arduino board, it’s a chip made by Atmel that you can program with the same code as regular Arduino boards.  Almost all Arduino boards use these Atmel chips (called “AVRs”) so it makes perfect sense that you can also use just the chip to make your projects super small.

You Can Simulate a 555 Timer in 123D Circuits

It is an absolute joy to make this announcement about a tiny, unassuming chip that has changed the world:  You read it first here.  You can simulate a 555 in 123D Circuits!

Whether you knew it or not, we've all touched a 555.  They're inside appliances like toaster ovens, microwaves, alarm clocks, little robots, zillions of toys, early computers and even a few spacecraft.  They're everywhere!

Don't believe us?  According to their original 1971 inventor, Hans Camenzind, production has steadily ramped up to an astonishing 1 BILLION 555s being made per year, and they crossed that threshold in 2003!


For the announcement we put together an example circuit that when connected to a servo lets you control the angle (or position) by turning a potentiometer.  Click the Read More button to load it.   Read more »

Harsha P’s Clock Simulation is Right-on-Time

123D Circuits user and Instructables contest finalist Harsha P is back in the news again with his most excellent digital clock simulation.  Try it out, press the PLAY button in the upper right corner:

"Hours" by Harsha P.


Although Harsha does make printed circuit boards he has mostly focused on the breadboard simulation in 123D Circuits.  He says his favorite aspects of the application are the multimeters that can pinpoint the voltage at any node and measure the current through loops.  We agree, the multimeters are great, check out an example below:

DIY Sound Circuit Comes To Life

New Orleans has Mardi Gras, Austin has SXSW, and here at the123D HQ we’re getting into the groove with our new musical theme: #LISTEN3D

One of the projects we’ve been working on is a theremin-like circuit that makes cool, R2-D2 style sounds that change pitch based on how much light it detects.  Move your hand in front of it, the sounds change - it's super easy to build and tweak! Twist or press a button and the sounds change even more! 


 Here's another video of the same circuit hooked up to an Oscilloscope.

This circuit is inspired by the designs in Nicolas Collins’ book Handmade electronic Music and you can build your own based off the plans right here in 123D Circuits. Nicholas Collins is “a pioneer in the use of microcomputers in live performance, and has made extensive use of 'home-made' electronic circuitry, radio, found sound material, and transformed musical instruments.” 


Update: We used 123D Circuits to turn the hands-on breadboard into a real, professional printed circuit board.  Here's a blog post on it.
