Analog vs. Digital

Resources and Going Further

Now that you know the difference between analog and digital signals, we'd suggest checking out the Analog to Digital Conversion tutorial. Working with microcontrollers, or really any logic-based electronics, means working in the digital realm most of the time. If you want to sense light, temperature, or interface a microcontroller with a variety of other analog sensors, you'll need to know how to convert the analog voltage they produce into a digital value.

Also, consider reading our Pulse Width Modulation (PWM) tutorial. PWM is a trick microcontrollers can use to make a digital signal appear to be analog.

Here are some other subjects which deal heavily with digital interfaces:

• Binary
• Logic Levels
• Serial Communication
• SPI Communication
• I²C Communication
• IR Communication

Or, if you'd like to delve further into the analog realm, consider checking out these tutorials:

• Voltage Dividers
• Resistors
• Diodes
• Capacitors
• Transistors
