[/x_accordion_item][x_accordion_item title=”Step 1″ open=”false”]If you have a 3rd third hand it makes soldering much easier due to the small size of the PCB.

  1. Start with the SMD switch. It can be placed either direction.
  2. Apply solder to 1 of the pads.
    While heating the pad place the switch.
  3. Once aligned remove the heat.
    Solder the rest of the pins.

[/x_accordion_item][x_accordion_item title=”Step 2″ open=”false”]

  1. Insert each resonator and bend the pins slightly to the side so they don’t fall out when you flip it over.
  2. Flip over and solder each of the pins
  3. Clip the leads just above the solder joint.

[/x_accordion_item][x_accordion_item title=”Step 3″ open=”false”]Holding one side of the headers apply soldering to the opposite side and opposite pin, careful not to burn yourself.

Once aligned solder the rest of the pins.

Pin 1 is G and is marked with a G. The other two are the crystalresonators pins. Most if now all AVR microcontrollers have ground next to the two crystal pins. So you should be able to just plug it in. If this isn’t the case you can use jumpers on the breadboard to connect to the correct pins. Here is an example with a ATmega328p.[/x_text][/x_column][/x_row][x_row inner_container=”true” marginless_columns=”false” bg_color=”” style=”margin: 0px auto 0px auto; padding: 0px 0px 0px 0px; “][x_column bg_color=”” type=”1/1″ class=”center-text ” style=”padding: 0px 0px 0px 0px; “][x_image type=”thumbnail” src=”http://learn.friedcircuits.us/wp-content/uploads/2013/11/DualResonatorBreadboard.jpg” alt=”” link=”false” href=”#” title=”” target=”” info=”none” info_place=”top” info_trigger=”hover” info_content=””][/x_column][/x_row][x_row inner_container=”true” marginless_columns=”false” bg_color=”” style=”margin: 0px auto 0px auto; padding: 0px 0px 0px 0px; “][x_column bg_color=”” type=”1/1″ style=”padding: 0px 0px 0px 0px; “][x_text]

It is probably best to set the speed while the microcontroller is powered down. As a test you can load the blink sketch and connect a LED and resistor to pin 13. If you change the speed without changing the board settings in the Arduino IDE the LED blink speed will change. [/x_text][/x_column][/x_row][/x_section]
