Circuit Lab HD

Circuit Lab HD for iPad via DP.

Circuit Lab HD is an electronic circuit analysis tool based on the modified node analysis method.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. I, for one, am getting very tired of reading about iApps for iDevices built by one of the maker unfriendliest consumer companies in the world in the feed from Adafruit. If you’re going to flog iDevices, make a separate feed for them so I can unsubscribe and stop wasting my time skipping over them.

    If you need a circuit analysis tool, go to https://6002x.mitx.mit.edu/courseware/ and use the circuit analysis tool. It runs on a web browser, it doesn’t require homage to the ghost of Steve Jobs, it does the right thing, and you can watch the videos and learn what the younger Terman wrote it to do.

    Sorry for the grumpiness, but you do feature a lot of this sort of … stuff which doesn’t do most people running on most computers, most cell phones, most tablets any benefit at all. So skip it. If it doesn’t work everywhere, it creates needless divisions in the community.

  2. @roger, thanks for posting up – we try to be inclusive and cover learning tools from all sorts of operating systems and platforms.
