### Digital circuits

1. 1. DIGITAL CIRCUITS<br />By: Matt Vennekotter<br />
2. 2. Simple Circuit<br />A simple Circuit consists of three main components:<br /><ul><li>Voltage = V
3. 3. Resistance = R
4. 4. Amperage = I</li></ul>Voltage is usually a battery.<br />Resistance can be a light, motor, or a heater.<br />Amperage is the pressure of the electrons travelling through the wire.<br />The basic relation between these three parts is V=IR<br />
5. 5. Logic<br />Everything in life can be defined as yes or no, on or off, yin and yang, etc.<br />In logic the binary system is used which is usually represented as 1 meaning on and 0 meaning off.<br />
6. 6. Gates<br />Gates are used to change any amount of input its given into one output.<br />Using gates help organize inputs to get the output we want.<br />Like on any electronic, there are several inputs and several outputs.<br />On a microwave the buttons are inputs while the microwave turning on is an output or the digits on the clock are outputs.<br />
7. 7. Microwave Sample<br />Every single button on this is an input.<br />The output includes every little dash on the display, the turning of the microwave table, and of course the warming up of your food.<br />
8. 8. Simple Gates<br />The simple gates include the OR, AND, and NOT gate.<br />On the AND and OR gates there’s two inputs and one output.<br />This means there’s four possible combinations of inputs.<br />The NOT gate has only one input so there’s two possibilities of inputs.<br />
9. 9. AND Gate<br />The AND gate simply means that when your inputs are both ones, then the output is a 1. <br />
10. 10. OR Gate<br />The OR gate gets a 1 output as long as one of the inputs is a one.<br />
11. 11. NOT Gate<br />The Basic function of the not gate is to invert the number its given.<br />
12. 12. Summary<br />Through a combination of these gates and several other types of complex gates we can build machines that are able to interpret input and give the output we were looking for.<br />First step in making a circuit is figuring out your input and your output. Through the use of Boolean Algebra and other methods, circuits can be made to run our everyday life.<br />
