When my Arduino UNO kit came in the 16 x 2 Liquid Crystal Display didn’t have connecting pins or wires connected to it and salvaged liquid crystal displays don’t always have pins or wires you can use. In this Instructable I will show how to add connecting pins to your Liquid Crystal Displays so you can plug them into breadboards, circuit boards or attach them to leads.

Step 1: The Liquid Crystal Displays

Other than the 16 x 2 liquid crystal display I got with my Arduino I have a number of displays I salvaged from electronics I dissembled for the useful parts.

The Arduino is a 16 x 2 LCD with 16 through holes for wires or connecting pins, 8 data inputs and 2 for LED light.

The LCD beside the Arduino LCD is a 16 x 2 LCD with 14 through holes for connecting pins or wires, 8 data inputs.

The next LCD is a 16 x 1 LCD with 10 straight connecting pins 4 data inputs.

And the last LCD is a 16 x 2 LCD with long enough leads to keep as is, 8 data inputs and 2 for LED light.

The LCDs I am going to add pins to are the first two.
<p>ooo yes! I have a lot of LCD's salvaged from old equipment.</p><p>a good idea. </p>
I like your reuse philosophy. I have a mother board destined for the electrical recycle bin, so I am going to emulate your approach with the propane torch this weekend. Hopefully I will get some nice connectors. Thanks for the reminder to reuse and recycle. Always!
<p>consider using a heavy duty paintstripper. that works well too</p>
<p>I have tried several paint stripers all they did was soften the PCB resin.</p><p>Joe</p>
I should have done a video of using the blow torch it is a little tricky. <br> <br>Do it outside that way if the circuit board catches fire you don&rsquo;t fill the house with smoke. <br> <br>It is a fine line between hot enough and to hot you will know you are close if you here little popping sounds. <br> <br>Joe
Well, I tried this and it certainly works very well. The best way to describe it that there was a <strong>rain of components </strong>falling around me as I swept the torch over the board. How well they will work remains to seen. Certainly all the connectors look good. I second the &quot;do it outside..&quot;, as I set off the smoke detector in the garage&nbsp;and DID fill the house with smoke. Thanks again for the instructable.
You can be sure half the components don't work but the IC sockets connectors and heat sinks should be fine, what gets to the semi conductors and other components is they have connections inside and the connections become desolder when they get to hot. one trick is the black and pink spring loaded tweezers the heat goes into the tweezers and not the IC.
