I was struggling for the last few hours trying to solder up my LCD, this video saved the board! Thank you so much, it was super informative and allowed me to continue my project!
It makes it look so easy on the best terms of my local electronic store I keep trying and destroying He has a proper temperature controlled solder station
Thank you. I've been struggling to find a good brief tutorial on the basics of soldering. I was able to solder my LCD and it worked great. The tips about how much solder to put, what you do if you put too much, how to touch it up, which way to move the tip when done... Really helpful. Thank you, again. Thumbs up for sure. =)
Hello, can you help me with a question I have on LCD displays. I have to replace a failed 1601 16x1 VER 2.0 bluedisplay. I can't find anywhere a display with the same exact information and I don't know enough about displaysto know if a 1601 is the same as a 1601A as well as the VER 2.0 and if that is critical. The display is for a frequency countercalled a DD-103Thanks, Ken
LOL, i could not do it yesterday, and I got terribly angry and smashed my 2*16 LCD against the ground, now i know how to do it, thank sir, from Iraq, I really appreciate this video, liked and subscribed
hi should it also work without soldering or its necessary? I just 'attached pins', connected it to the board and my lcd turned on but it did not receive any data from Arduino, (double checked the wiring and it s fine)
Intermittent display. Sometimes no LCD, sometimes no backlight. I thought LCD was bad to I replaced it but I suspect either the wires are bad or my soldering isn't up to scratch. Thanks
ArcanePath360 When you are soldering the pins, please ensure the pins and the pad on LCD have been wrapped by the melt tin as quickly as possible. Please note that the two pins can not be soldered together directly. You can try to add some melt tin.
Melt tin - you mean solder? I did do it quickly but maybe too quickly. I'm guessing I have 1 or 2 cold joints. I also didn't use header pins but directly soldered the wires to the pad. I would throw it out and get a serial one, but I'm already using the SDA ad SCL pins
hi my display is working fine at first, my supply is a connected to a resistor to change it to 5V(i have also used 7805 voltage regulator IC and 5V zener diodes), but then when the supply (12V battery) is being charged by a DC generator we noticed that the regulating voltages we use is not working anymore which in turn makes the LCD display random characters. Please help! Thanks
Dear Norberto, The voltage problem will cause that the LCD dispaly is not clear, flashing or burn it. Not the random characters, random characters are generally due to the data is not correct, or LCD is not initialized or unstable wiring. Pls check the situations we have mentioned. If you still can't find it, pls connect with us and provide more details about the problem.
The display is alternating between random ASCII characters and the proper display. But when the generator is not charging the battery the display is at a stable proper display
Dear Norberto, It should be the DC generator problem. If you have oscilloscope, you can check the output of 7805, after connected the generator. In additional to, could you pls provide some picture or circuit diagram about the cables connection? We still can't understand your problem totally. Looking forward your reply!
Look at the percentage of “flux”. Flux let’s it melt. I would buy wire with 2 percent flux it. Also try to buy “clean” wire, eg without lead. Lead is very, very unhealthy. Cost a bit more but is worth it. Best regards, Leo The Netherlands.
haha,thanks for your attention if you saw it first time,maybe you You don't know it.If you want to know more,welcome to visit our website. www.sunfounder.com/index.php/ nice day
So they get warm enough to actually accept the solder.. If you just drop hot solder on a cold pin you'll get a cold connection which doesn't work or works very unreliably.
