HackSpace Magazine Issue 29 – adding a character display to your project @HackSpaceMag
In the new HackSpace Magazine Issue 29, Ben Everard writes about adding a character display to your project. The character displays can be programmed with Arduino or CircuitPython.
Displays come in all shapes and sizes, and it’s not about there being an overall ‘best’ display so much as it is picking the right one for your project. This month we’re going to look at character LCDs, which are cheap, widely available, and easy to program with most development environments.
Almost all of these are controlled by Hitachi HD44780 chips, and can take input in a couple of forms. In their bare incarnation, they have a parallel data bus which has 16 pins (though not all are needed), but there are also versions with I2C or SPI input.
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
