im using the tinkercad arduino software and this is a link to my project. For someone willing to help I would be able to send a link where you would be able to edit a copy of the code/circuit board inside the online software.
I have been trying to fix this bug since december and would really appreciate some help.
Tinkercad will give that error message when something else is wrong.
I tried a simple circuit with the #include , that works.
I tried to compile the sketch in the Arduino IDE, and it compiled without problem.
I tried it in the Wokwi simulation, and it compiles and runs. But the Adafruit library might not be compatible with the Wokwi LCD display.
Since Wokwi can use every library, I suggest to go directly for the best library: "hd44780".
Perhaps Tinkercad has a older version of a library which is not compatible with the rest.
Perhaps you can replace the troubles lines with other functions? And perhaps you should avoid using the String class on a Arduino Uno. You can also use the F() macro to reduce SRAM usage.
As I said, Tinkercad will give that error message when something else is wrong.
However, both UKHeliBob and me confirm that the code compiles in the Arduino IDE, and I have tested it in Wokwi and it compiles and runs also there.
You can not keep trying to find out what Tinkercad does not tell.
Step out of this. You need something completely different. Either other code in Tinkercad, or Wokwi simulation or the Arduino IDE for a real project with real hardware.
Was bored here at work so I went through your code and commented out all calls to lcdPrint2. Error went away. Then I started uncommenting them one by one and about halfway through, the error came back.
Definitely a TinkerCAD issue.
Hello, Arduino community,
I am a student trying to make two thin-film pressure sensors turn on 4 separate green LEDs and one LED ring (a WS2812 ring to be exact). The code works so when one is pressed it should turn on 2 LEDs and the ring to half brightness. When both are pressed at the same time it should turn on two.
Currently, when uploaded when I apply pressure to the Arduino it reads at 0 and does not turn anything on. I have attached my code and a diagram to this post and any help would be lifesaving. (ps the resistors for the orange wiring are positioned on the right side of the breadboard-in tinkercad it wouldn't let me position it there).
Don't connect a real Arduino like that. There are so many mistakes that I lost count. The worst mistake is that you have shorted the 5V and GND pins which will cause the Arduino to reset and could damage your pc/laptop or if you are lucky, only cause the pc/laptop to give an error message and cut usb power to the arduino.
I'm trying to make a code for a product that when charged turns on led lights at the top to mimick UV lighting. The sensors go on top of a standard power board and are turned on when someone charges a device.
I can say that with 24 RGB LEDs, the Arduino cannot provide enough power to light your ring, you will need a separate 5V power supply with maybe 2A current. This would be capable of powering the Arduino as well as the led ring.
Looking back at your original diagram, I think I see what the general problem is. You think the breadboard holes are connected together in horizontal rows? It's the vertical columns that are connected together. The horizontal channel in the middle of the breadboard is where there is a break in those connections, the columns in the top half of the breadboard are not connected to the bottom half.
Some breadboards have some horizontally connected rows at the top and bottom, like the red and blue in this picture. But in the main part of the breadboard, the connections are vertical, shown in black above. Your breadboard doesn't have those horizontal rows, assuming it looks like the one in your wiring diagram.
in this tutorial you will learn how the force sensor works and how to interface with Arduino in tinkercad. The force is use to detect the pressure, amount of weight applied on the sensor, there are many applications of force sensor like it is used in electronic drum, gaming devices, industrial electronics etc. These sensors are good for measuring pressure but not highly accurate for measuring the weight.
The hardware a part of this project is quite simple and easy to place together. First of all, make the connections for the force sensor with the Arduino. The connections for the force sensor with the Arduino given in the above circuit diagram.
The force sensor we used here has size 2 inch. force sensor has two pins one is connected to the GND pin of an Arduino and another pin is connected to the digital pin of an Arduino using the voltage divider across this pin.
If the FSR value is less than 30 then pin 5 will be and pin no 4 and pin no 3 will be Low. This will make blue LED to turn on and other two LEDs will turn off this indicates the low pressure applied.
If the applied force value is less than 220 and also If the applied force value is greater than 90 then pin 4 will be high and pin no 5 and pin no 3 will be Low. This will make yellow LED turn on and other two LEDs will turn off this indicates the medium range force is applied on FSR.
Explore the written of language of braille, whilst teaching students 3D modelling concepts. 3D printing opens up a world of opportunity to create bespoke, on-demand braille models. You may wish to create simple braille blocks or take it a step further and create braille signage for different areas of your school.
Teach students about sound waves, frequency and amplitude before challenging them to design a whistle. With the use of an iterative process, students can analyse and evaluate their creations to improve on their designs.
Create pen cases by using intersecting shapes such as pebbles drawn in Tinkercad. In this example, students learn about mathematical linear sequences to determine how many pebbles are required to achieve the right sized pen case for a Bic Cristal biro cartridge to slot into the centre.
What better way to learn about Egyptian Hieroglyphics and monuments than getting students to design their own obelisks! Using a hieroglyphic alphabet, they can go on to personalise their obelisk model with their own name.
Whether its population, life expectancy or any other demographic, 3D bar charts make presenting information much more interesting and readable than basic 2D graphs. You may wish to consider using demographic or survey information from your school to create 3D bar charts that show information that is specific to your school.
Combine toy design with concepts of forces and motion by guiding students in creating spinning tops. Once 3D printed, students can compete to see whose spinning top can spin for the longest before analysing the results and making improvements on the design.
Explore historical and architectural concepts of the Great Wall of China. Students can use research methods along with their own unique interpretations to recreate these famous relics of the Great Wall.
For those with arthritis of the fingers or those with a weak grip, opening screw cap bottles can be extremely difficult. Luckily, with the use of certain tools in Tinkercad, students can create assistive devices such as bottle openers. Whilst designing they can learn about simple machines and the principles of levers.
I have noticed that it usually takes 5 tries to get a design right. Sometimes these can be total rewrites of your software library, or like this time around, it took me 5 tries to design a pair of scissors.
The first design was total disaster. For some reason I designed the scissor blades the wrong way around! Silly me. In my very first attempt I did not realize that both blades are actually printed laying on the same side, that is, the second blade is not mirrored.
In the second design I also tried to address what happens when you press the handles together. I made the handles twice as think as the blades. This worked well, but the handles were too close to each other, there needs to be gap.
In the third version I separated the sides a bit and added a small nob there so that the handles would stop at right angle. Still not working, though! The handles are too close to the joint. That prevents the blades to open enough and there feeling is not quite right. It needs more leverage.
I used the same joint mechanism as I used in my Strandbeest prototype. There are two washers which are fastened together with an 12mm M3 screw and everything is slightly loose fit so that the blades rotate even if the whole package is fatened tight.
So this is how the design process usually goes. You make a desing, make it, analyse the problem and improve it. It is super rare that you get something right the first time you try it. You usually find the most glaring problems initially, sometimes it takes few months of use to find the final tweaks.
There is one more thing I would like to improve about the scissor design. For right handed scissors the topmost blade should be on left side. This allows you to apply some force to push the blades more tightly together and make more accurate cuts. That would be the 5th, perfect, design ?
You are right, i have to tinkercad slot. Regarding the wing, i use 3d printed as it has to, make a prototype as a lot of thing have to be made. If wing really sucks, it will be time to use a real one.
