The Digital Die

1 Soldering the board

Build It

  • Your initial board should look like this.

  • You should be able to solder on the first few components without any guidance.
  • Start with the smallest components first.
  • Make sure the diode and the 78L05 voltage regulator are in the correct way around (or you might give yourself a bit of a suprise).
  • Your board should look like this when it is finsihed.

Build It

  • Don't forget to pass your battery snap through the strain hole as shown below before soldering it on.

Build It

  • With the basic components soldered to the board, you now need to add in the LEDs.
  • The LEDs will be fitted using 2 spacers.
  • Follow the guide below carefully.
  • Take an LED and the two spacers.

  • Place the one LED through the centre of the spacers.

  • Now holding the LED and spacers together, place the carefully on the PCB and solder the LED in place.
  • Make sure the LED is as close to the spacers as can be when you are finished soldering.
  • You can now get the next 6 LED's ready.

  • You can now add the rest of the LED's. Make sure you have the long leg(+) in the correct hole.

  • Now you must download your program to the board and test it before continuing.

Badge It

  • Take a picture of the solder side and component side of your board.
  • Upload your program to your board and make sure it works. Take a photo of your board working.
  • Your badge will be awarded according to the quality of your work.
  • The silver badge progress ladder, green - Solder more challenging components (e.g. ICs) to a PCB, with assistance.
  • This gold badge progress ladder, blue - Confidently and consistently solder components to a high standard.
  • This platinum badge progress ladder, indigo - Produce working boards to a high standard, ensuring wires are correctly dressed and soldering is tidy.
