Many materials are available on which to build prototype circuits. The material chosen will depend on the required life and use of the circuit. For laboratory use or other short-term applications where a permanent circuit is not needed and operating frequency is below 10 MHz, solderless breadboards such as that shown below can be used.
The board comprises:
There are three banks of LEDs on the left hand side of the board for signal output:

Common Ticking Criteria
All of the workshops should be written up in full in the style of a laboratory log book. You may use an actual log book or else loose sheets with page numbers. From your notes it should be possible for somebody else to be able to reproduce your work. This is good scientific practise. When an exercise is complete and written up, including answers to the questions, the final page will be signed by a demonstrator and a tick entered in the tick sheet.
We recommend that you draw out circuits in your log book before wiring them up. Put pin numbers for the connections to each chip.
VERY IMPORTANT: you need to hand in this assessed exercise as part of your portfolio of work at the end of the year (see the Head of Department's notice), SO YOU MUST KEEP YOUR WORK!
