====== Getting Started with the Breadboard Breakout for Analog Discovery ======

This guide will walk through the process of setting up a simple circuit, applying a waveform to it, and reading the results using the Analog Discovery and Breadboard Breakout.

===== Prerequisites =====

=== Hardware ===
  * **An Analog Discovery 3 or Analog Discovery 2**
    * //Note that the guide below was written for the AD2, however, there is no functional difference when following the same steps with an AD3.//
  * **A Breadboard Breakout for Analog Discovery**
    * //This can be purchased from its **[[https://digilent.com/shop/breadboard-breakout-for-analog-discovery/|Digilent Store Page]]**.//
  * **A breadboard and circuit to test**
    * //The circuit constructed in this guide requires three identical resistors and several jumper wires.//

=== Software ===
  * **Digilent Waveforms**
    * //Follow the **[[/learn/instrumentation/tutorials/analog-discovery-2-getting-started|Getting Started with Analog Discovery]]** to install Waveforms.//

==== Set up a Circuit ====

=== 1. ===
The image to the right is a diagram of the circuit that will be connected to the Analog Discovery 2 through the Breadboard Breakout. Three 10Ω resistors are used to create a Voltage divider circuit, which will have a waveform applied from the **W1** pin of the Analog Discovery 2. The circuit will be grounded to the Analog Discovery 2, and will be probed at the two intermediate nodes using the **1+** and **2+** pins. The The **1-** and **2-** pins should be grounded to get accurate readings on Analog Channels 1 and 2.

=== 4. ===

Plug the Analog Discovery 2 into a computer with a microUSB cable and launch Waveforms. Open the **Wavegen** tab and create a //Sine// wave at //1kHz// frequency and //1V// amplitude on //Channel 1//. Click **Run** to apply this waveform to the Analog Discovery 2's **W1** pin.

=== 5. ===

Open the **Scope** tab. Since both channels of the Analog Discovery 2 scope are already connected to the circuit, enable both channels with an Offset of //0 V// and a Range of //200 mV/div//. Click **Run** to begin displaying the waveforms seen at the two intermediate nodes of the voltage divider circuit. As seen in the image to the right, Channel 1 will see a 1kHz Sine wave with an amplitude of 0.67V, while Channel 2 will see a 1kHz Sine wave with an amplitude of 0.33V.
