I built this display using the Micro:Bit and a couple of ☒CHIPs from XinaBox. It is a very simple and quick build. The XinaBox technology made this project extremely easy to do by eliminating the need for soldering and tools. The Micro:bit interface allows me to develop easily. You can easily modify the code to show whatever text you want and shape/image on the LED display.
Step 1: Assemble the circuit
- Click the OD01 and MD01 together using a ☒BUS connector (from the XC10pack).
- Insert the Micro:bit into the IM02 interface:
- Click the IM02 to the OD01 and MD01 using 2 XC10 xBUS connectorsDSCN1203.JPG
Step 2: Install package
- Open a browser and go to makecode.microbit.org
- Scroll down to "Advanced"
- Then Scroll down to "Add Package"
- Paste this URL into the search bar : https://github.com/xinabox/pxt-OD01 then click on OD01 to add the package.
- You now have all the packages you need this project.
Step 3: Programming
- Drag and drop code elements until you get something that looks like the image below.
Step 4: Compile and Test
- Drag the downloaded file, typically named: microbit-Untitled.hex, to your Micro:Bit drive, typically name: MICROBIT.
- See the result on the scrolling LED display and OLED screen.
Step 5: Complete Temperature Monitor
- Disconnect the Micro:bit from the Micro-USB connection.
- Insert the AA batteries into the PB04
- Use 2 ☒BUS connectors to connect the PB04 to the OD01 and the MD01 as seen below
- Turn the switch on the PB04 on.
- Now your Micro:bit Valentine's Display is portable and ready to be placed wherever you choose.
