The 7-part show « Adafruit Industries – Makers, Hackers, Artists, Designers and Engineers!

This week on the Adafruit learning systemAnd the We published an update of our LED Backpacking Guidewhich includes instructions on using one of my favorite Adafruit products, 7 compartment backpack. So today, let’s take a look at some of the many great guides that use the 7-segment display. But first, here’s my new favorite guide this week!

Plastic capsule containing electronics

Created by Lydia and Philip Burgess A new guide to help you cheat on your way to becoming a Chess Champion!

Social media has been fussing about the possibility of Cheating in strategic tournament matches. Does it happen? How is that possible with officials watching? Could there be a receiver hidden somewhere? What can be done to correct this? These are investigative questions!

We’ll get to the bottom of this by doing one simple method hidden caller Use Adafruit parts and the Adafruit IO . Service. Not for actual cheat Of course, that would be a disgrace…in short, a disgrace to the sport…but for the record to posterity whether this kind of back-streak is acceptable or just an internet legend.

If you’re making a simple alarm clock or a time machine within DeLorean, look no further than the simple 7-segment display. These projects will show you how.

Putting the big question out of the way: No, we wont These are sold. Legally, we I cannot For trademark reasons. But it is generally accepted for anyone to create replica props for their personal useSo we hope this article will inspire some great projects among our clients…

from the moment these Drove Displays Featured on our weekly Ask the engineer View, comparisons were made with the DeLorean Time Circle from Back to the future Movies. It was a moral imperative then to make a demo! If you come in handy with an Arduino and some shop tools, you should be able to get something similar (better, or even), or adapt ideas for other projects. This was built quickly in a fun way, so please don’t expect the same level of polishing as a tutorial for the final product.

Have you ever wanted to build a huge timer using 7-segment displays? Here’s a way to do it using NeoPixel sectional strips and acrylic diffusers to combine individual LEDs into seamless light sources.

This guide shows how to make 12 figures, each made of a meter of NeoPixels cut into strips and then joined at corners. Each digit is controlled by a single Arduino data pin, so you can generate and use as many digits as you want, depending on the power supply and the available Arduino pins.

Plus, you’ll create powerful buttons to start and stop the timer, and control the ear-slashing car horn from the Arduino!


LiDAR (short for Detecting light and range) is a technique that measures the distance to a target by shining a pulsed laser light on it and analyzing the reflections.

The surface on which the laser light bounces will affect how good a reading you get. Smooth reflective surfaces tend to bounce light away from the sensor depending on the angle at which the light hits the surface. If the light is coming directly to the surface, it will be reflected directly back and you will get a good reading. The further you move away from direct reading, the poorer you will get to read, and in the end you will not get a reading at all. Glass, mirrors, and any surface will be highly polished this way.


Inspired by Facebook’s “Reactions”. You press the button, and the number of digits is displayed on the LED screen.

It looks like a new product, but it can be used for all kinds of useful things like tracking attendance at an event, tracking a game score or anything else that needs a counter.

With so many clues to the Adafruit learning system out there, some great clues from years past are buried and lost. ALS Deep Cuts is working to bring this evidence back to the surface. This week’s guide from the past in 2018.

You can build a machine that draws cool geometric curve patterns using Crickit, Circuit Playground Express, TT and LEGO engines. This type of harmograph moves the armature from two motor axes operating at different speeds, generating and mapping complex harmonic motion!

Stop breading and soldering – start building right away! Adafruit’s Circuit is filled with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with MakeCode Drag and Drop Programming SiteLearn Computer Science with the CS Discoveries class at, go to Circle To learn Python and hardware together, TinyGO, or even use the Arduino IDE. Speed ​​Circuit Stadium It is the latest and best circuit board board, with support for CircuitPython, MakeCode and Arduino. It has a powerful processor, 10 NeoPixels, a mini speaker, an InfraRed transmitter and receiver, two buttons, a switch, 14 alligator clip pads, and a lot of sensors: capacitive touch, near infrared, temperature, light, motion and sound. A vast world of electronics and coding awaits, and it fits in the palm of your hand.
