Tools Wire used to draw connectors Selector used to select objects Gates create your circuits using these Switch control the inputs to your circuits Node nodes are used to tidy up lines LED An easy way to check an output

A Q Example Test an AND gate What will you need to draw? l l AND gate 2 switches 1 LED Wire and nodes B

Step 1 • Select AND GATE • Click to place on page

Step 2 • Select Switch • Click twice Don’t worry if they are not in the correct position

Step 3 • Select LED • Place 1 LED Use the Selector button to move the components around Turn on the Grid and set grid to 5 (View Menu)

OR Gate Step 4 • Select Wire • Draw wires • YOU MUST DRAW THEM FROM OUTPUTS TO INPUTS OUTPUTS INPUTS

Draw Wires

Testing Press Play Toolbox will disappear Press Stop to carry on designing

Testing Try changing the switches and watch the LED

Exercises l Create one sheet with: – AND, OR, NOT, NAND, NOR, XOR You can also create multi-input ANDs Use the selector to double click an AND gate to create a NAND gate
