I am a newbie in electronics.
I need a circuit (which I can use as a subcircuit) in Logisim 3.8.0
When the pushbutton is clicked ONCE, the LED should come on and STAY ON. Here when the clock sticks over, the LED turns off off. I want the LED to stay on!
When I click the push button the LED...
Hello,
This is my dirt bike speedometer (Suzuki DR 250R 98), I noticed the first two digits of the odometer faded, so my initial thought was a bad connection I thoroughly cleaned the zebra connections but the issue wasn't resolved so I tried to fix it by changing polarizer films, I didn't...
Hey there, this is my first time posting here. I definitely appreciate any and all help.
I've got a TI MSP430G2552 microcontroller that I am using, leftover from a class last semester. I also have a 16x2 LCD with the HD44780 controller/driver. I'm building the library and C files inside of Code...
Hello guys, I'm a student that really new to this codevision.
Today I am here to ask some problem to a professional in this field.
Yesterday our teacher give us a proteus project and the code in codevision about ultrasonic sensor.
and showing the sensor value on the LCD on the right.
And now...
While taking a taxi on a business trip, I saw an interesting thing. I was sitting in the back when I noticed a small touch screen TV installed in the back of the passenger side, which made my trip not so boring. I think I can also purchase a touch screen that can play the video and I can put it...
I accidentally hooked up the Arduino to a 12v power supply while using the Arduino Uno to connect to my screens and power them up, which made my board burn up in a heartbeat. I think maybe the 3.3v capacitor is burnt out, how should I repair it?
My board is normally connected to the computer...
Hi there. I have a 3D TV LG 42lw650s that one day stopped working. Attached images of what happens when turning on. The t_con board is not, since I changed it and the same thing keeps happening ... What could it be? Thanks in advance.

Hello,
I have been searching the Internet for days now, hours wasted scrolling through alibaba and aliexpress with very little luck.
I am looking for a 1 to 2.6 inch color lcd (doesn't matter if oled or tft or whatever) with a resolution of around 480x800 or similar with an aspect ratio of...
Greetings To All !
I am brand new to this forum and this is my first post. I have been struggling to find a resolution to an apparent common problem I am experiancing with a Visio Model SV370XVT flat panel TV. When the set is first powered on the display has a very narrow blue bar across...
I reciently faced a problem with a 2x16 LCD (4 bit mode).
Only one line was displayed.
The solution was disconnect the LCD's unnused data bits from ground, and let them float, disconnected from each others.
Has anyone experienced this??
Now for some background...
I breadboarded the full...
Hello
I am hoping someone can help me as I am pulling my hair out trying to figure this out and have tried following the limited information I can find about this online but like a lot of the information the steps given are not always complete which makes trying to figure something out as a...
I want to use one of the newer LCD character displays that has a generous 40 x 4 character screen. This is done using 2 controllers in effect, with two enable lines. Has anyone tried this with an arduino? I am not sure if you can define two separate LCD objects, and at the same time share the...
Hey everyone.
It's know it's been done 1000's of times before, BUT, I'm interested to know if the way I'm doing it is a good way.
So basically I'm driving a 4x16 LCD (44780 controlled) in 4-bit mode.
I set aside 64 bytes of ram (in bank 1) to use as LCD Character place holders.
Throughout the...
I am currently working with PIC microcontroller 16F877A. I am only allowed to work in Assembly (nothing high level like C). I have a number saved in a register. I need to display it on the LCD.
I was thinking of separating the digits, then sending the ASCII value of each digit. The only issue...
Hello,
Regarding Renesas part number R5F100LEAFB#V0: I have its data lines and control lines tied to an LCD (operating at 5V). The R5F100LEAFB#V0 has EVDD at 3.3 V. Will the R5F100LEAFB#V0 be damaged due to the voltage mis-match to the LCD (3.3V vs. 5V)?
Thanks,
Calvin
Hi,
I'm using ST7565R lcd with STM32F3 board but failed to initialize the lcd properly, I added the 1uf capacitors as per datasheet . I have observed 1.358V at the V0 pin and 1.359V at V1,V2,V3,V4 pins . And I have attached my code here, please help me someone to resolve my problem.
Hi
I hava a HundaTech 4.3" I2C TFT Display (Link Below) and want to display value read from the analog pin of my arduino DUE. The communication config i using is I2C
Has anyone successfully managed to get the display on the lcd...
Hi guys, i'm doing a project with an unknown multiplexed LCD, i don't know any of its caracteristics besides its a 16x3 LCD with 33 pins, i'm trying to do the pins mapping but i'm not succeeding at this :/, i've tried several things like using the multimeter with the continuity mode to try to...
I am working on a project for school. Using a keypad I have set "1" key to display my name. When I press the "*" key, I want to read what's on the LCD and compare it to data stored on the PIC18f4520. Go to the next line and translate it to Japanese. The only problem I am having is getting the...
