Firstly I had to choose the right type of Sundial. Horizontal Sundial are easy to make, but the gnomon has to be mounted at the angle of your latitude, so if you change location you have to adjust the angle of the gnomon and the positions of the hour marks on the plate. In equatorial Sundials the gnomon is perpendicular to the plate and then the entire plate is tilted at latitude angle plus the hour marks are evenly spread every 15 degrees. I chose the equatorial Sundial because you don’t have to adjust the hour marks and it’s easy to tilt the entire plate at latitude angle.
I also had to come up with the system for the Sundial to find North-South direction so I used digital compass HMC5883L and continuous rotation servo. To find latitude I used Neo 6M GPS module.
As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email firstname.lastname@example.org to let us know about your post so we can blog it up here.
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.
