Kitronik Alarm Clock Kit with ZIP Halo HD for micro:bit
Explore time, light, and also sound with the Kitronik Alarm Clock Kit, a fun and hands-on introduction to the ZIP Halo HD.
KITRONIK ALARM CLOCK KIT
The Kitronik Alarm Clock Kit with ZIP Halo HD for microbit provides a fun introduction to features of Halo HD. This kit features a modified version of Halo HD, all of the parts required to build the clock, and also power accessories. We have included an easy-to-follow tutorial book which will guide you through building your clock. Additionally, there are online tutorials within MakeCode.
The modified version of Halo HD changes are as follows; power is now provided via a 2.1mm barrel jack connection and there is also a coin cell holder fitted to the rear of the board. When a 1220 coin cell battery is inserted, it will then provide power to the RTC chip when no power is being supplied to Halo HD.
ZIP HALO HD
The Kitronik Halo HD board for the BBC micro:bit incorporates 60 individually addressable full-colour ZIP LEDs. It also breaks out P1/P2 to a standard 0.1” footprint, it features a MEMS mic for detection of sound, and a buzzer to play sound. It also features an onboard real-time clock (RTC). The board has M3 mounting holes for a more sturdy project.
Kitronik has created custom blocks for the ZIP Halo HD for use with MakeCode. To add these blocks; Under the “Advanced” section click on “Extensions”. In the next window search for “Halo HD”. Then, click on the tile to import it into MakeCode. You will see that the blocks are split across three categories; ZIP LEDs, Microphone and Clock. For those requiring more of a challenge, the Alarm Clock Kit kit can also be coded with MicroPython.
Kitronik has also produced 4 tutorials for you to explore once you've finished the supplied booklet. The tutorials are in two formats, downloadable PDFs and also as tutorials embedded in the MakeCode editor. You can find the links to all at the bottom of this page. Kitronik has also produced some example MicroPython code that covers how to code a basic clock.
POWERING THE ALARM CLOCK KIT
The ZIP Halo HD supplied with this kit is powered via a 2.1mm Barrel jack connection. The kit is supplied with a 3 x AA Battery Cage with Lead and 2.1mm DC jack. The adapter cable is for use with a separate power supply (not included). A regulated supply is produced on the board to power the connected BBC micro:bit. Halo HD has also been fitted with an ON/OFF switch, switch it off when not in use and the onboard coin cell will keep the memory of the RTC chip alive.
- The BBC micro:bit is NOT included in this kit.
- No soldering is required.
- Some quick and simple mechanical assembly is required.
- Ensure that when using a power supply that it is rated for at least 1A and 5V.
