Introduction The proto-screwshield (http://adafru.it/aIH) is the ultimate breakout board for an Arduino. It combines a prototyping shield with a full set of 3.5mm screw terminal blocks. The protoshield part lets you build custom circuitry and then you can easily & securely connect wires and sensors to the terminal blocks. Great for panel mounts, buttons, sensors, enclosures etc. The shield even comes with stacking headers, (http://adafru.
The proto-screwshield is based off of the Screw Shield by WingShield Industries (we just added a prototype area! (http://adafru.it/cmb) © Adafruit Industries https://learn.adafruit.
Make it! Let's go! This is a vey easy kit to make, just go through each of these steps to build the kit. 1. Tools and preparation (http://adafru.it/cDC) 2. Check the parts list (http://adafru.it/cDD) 3. Solder it (http://adafru.it/cDE) © Adafruit Industries https://learn.adafruit.
Preparation Prep Learn how to solder with tons of tutorials! (http://adafru.it/aTk) Don't forget to learn how to use your multimeter too! (http://adafru.it/aZZ) Tools There are a few tools that are required for assembly. None of these tools are included. If you don't have them, now would be a good time to borrow or purchase them.
So lder You will want rosin core, 60/40 solder. Good solder is a good thing. Bad solder leads to bridging and cold solder joints which can be tough to find.

Multimeter You will need a good quality basic multimeter that can measure voltage and continuity. Click here to buy a basic multimeter.

Flush Diago nal Cutters You will need flush diagonal cutters to trim the wires and leads off of components once you have soldered them in place.

Useful in cleaning up mistakes, every electrical engineer has one of these on their desk. Click here to buy a one (http://adafru.it/148).

Solder it! This tutorial page is for the pre-R3 version of the shield, so the photos may be slightly different, however the overall assembly procedure is the same! Assembly of the shield is pretty easy and should take you maybe 20 minutes maximum. First, check you have all the components. The green-pcb photo shows the older rev of the kit, The blue-pcb photo shows the R3 version - we now include an extra 10-pin stacking header and a 2x3 stacking header © Adafruit Industries https://learn.adafruit.
You'll need to slide the terminal blocks together. They come in 2 and 3-piece parts but you can easily connect them to make any size. Get ready by putting the PCB in a vise. Then you can start by placing one of the 8-piece terminal blocks in the "Analog" breakout area. Check to make sure that the terminal blocks are facing the right way! You want the 'mouth' to face outward. The terminal blocks should 'press fit' pretty nicely so they stay in place.
Flip over the PCB. And solder the pins to the pads. Use plenty of solder so that you get the pads completely filled. © Adafruit Industries https://learn.adafruit.
Place the remaining terminal blocks, checking again that they face the right direction! You can also just put the PCB with terminal blocks upside down on a table, which will keep the blocks in place while soldering. © Adafruit Industries https://learn.adafruit.
Next you can place the four 'stacking' headers. They go right next to the terminal blocks. With the new R3 version, you'll use 1 pc 10pin stacking header, 2 pcs 8 stacking header and 1 pc 6 stacking header Flip over the PCB, you can lay it down on a table again, just make sure that all the headers are sticking out straight. © Adafruit Industries https://learn.adafruit.
Solder all the pins of the header with plenty of solder. Next we'll place the two LEDs. The first LED is the green-colored one. This will tell us when the Arduino and shields are powered. LED's are directio nal which means you need to place it in the right way or it wont work! Check the LED to find the longer pin. This is the po sitive lead. That lead goes into the hole closest to the silkscreen '+' In the image to the left, the longer lead is to the left. © Adafruit Industries https://learn.adafruit.
Next is the red LED. This LED can be used for pretty much whatever you want, although we suggest connecting it to pin 13 to act like a debugging LED. Remember that the LED is directional, and the longer lead is positive. In the image to the left, the longer lead is to the left. You can bent the LED leads out of the way to keep the LEDs flat against the PCB. © Adafruit Industries https://learn.adafruit.
Solder both LEDs in place. © Adafruit Industries https://learn.adafruit.
Use the diagonal cutters to clip the long LED legs. They should be cut just above the solder joint. This will keep them from shorting against stuff. Next we will place the two 1.0Kohm resistors. These resistors are used to set the brightness of the LEDs. If you want brighter LEDs you can substitute 220 ohm resistors. If you want dimmer LEDs, you can use 4.7Kohm. Resistors do not have 'direction' so they can go either way and work fine.
Solder and clip the two resistors. Last we will place the reset switch. This switch will let you easily reset the Arduino. Tactile switches are symmetric, so you don't have to worry about putting them in wrong, and will snap into place flat against the PCB. Place the switch next to the RESET text. Clip the tactile switch legs. They're pretty short but they are right on top of the DC jack so the shield will sit better if you clip them! © Adafruit Industries https://learn.adafruit.
That's it! You can now insert the headers into the Arduino and start using the shield! © Adafruit Industries https://learn.adafruit.
