Learn how to create a simple gear indicator for the manual transmission of the car. For that, we will use Arduino UNO with SSD1306 128x64px IIC OLED screen and 4 Hall Sensors to measure the magnetic field of the magnet placed on the shifter handle. All the images are drawn in Photopea and converted into C-style arrays using the Image2cpp utility. For a WOKWI simulation, potentiometers are used instead of Hall sensors for testing (since WOKWI does not support Hall sensors). We will also create a custom PCB in KiCad and manufacture it by PCBWay. If you want to follow along, having some wires and a breadboard is helpful. Good luck with your project!

@cdgonepotatoes4219 2 месяца назад

Rewriting instead of copying and pasting is typically better for learning as you'll be better able to make out what's what, but if it's your code and mostly you're copying the boring stuff like a screen setup then you can't argue that it's bad. One cool thing you could do is creating a whole folder of "blueprints" for a specific function or component setup, all made by you, to copy and paste them in future projects. Be careful when copying someone else's code. Different people think different ways and if you don't understand what they've written you can hardly say you leaned anything (of course, learning might not be your goal and you can ignore this point). Check other people's code with the goal to understand their thought process, see how a peer tackled a certain problem, and only when you understand it you can feel free to copy, or maybe you had an epiphany while studying and you came up with a different solution that is more familiar and comfortable to you.

If you port the project to an arduino pro micro or leonardo, you can use the Joystick library to make it a functional game controller! also, wicked photoshop skills. I think i learned more about photoshop from this video than i did about arduino, lol

@upir_upir 2 месяца назад

That´s an intersting idea! Using Leonardo would be the easiest, as it shared the same pins with UNO. Unfortunatelly using this as a real shifter for a game is challenging, since the shifter does not stay in the place when it´s not connected to the transmission, so you would need to make some adjustments... but surely and interesting project to try!

@Flameancer 2 месяца назад

You make it look so easy. I’d have no idea where to even begin.

@upir_upir 2 месяца назад

Don´t worry; I did begin around a year ago by purchasing a spare shifter handle and then spending several months thinking about how to do that. It takes just 40 minutes in the video, but it took me quite some preparation time... that said, hopefully the video is simple enough to understand and shows the basic steps. If you can connect one hall sensor to arduino, you should be able to finish the project.

@Apfelloch Месяц назад

Using Hall effect sensors is ingenious! I've wanted to build a gear indicator for quite some time now for our 30+ years old camper van. Other tutorials used two potentiometers with pieces looking like tuning forks attached to them that "clamp" to the shifter handle. One is measuring the degrees from top to bottom and the other one from left to right. It's just another way to get input data but the rest is similar to your implementation. With Hall effect sensors I don't even need a 3D printer, which is nice (although I should get one anyway :D)

@upir_upir Месяц назад

Thank you for your comment. I have seen the other implementations using two "forks". I like that it only uses two analog input pins, and you can probably get a better and more accurate reading, but I don´t like that you are physically modifying the shifter handle, and there is a possibility that the shifting might not be that smooth. Worst case, it somehow gets stuck and you cannot shift at all. My solution is "non-invasive", and besides adding a small magnet to the lever, you are keeping everything intact. It would be probably better to make it more sturdy by adding some 3D printed enclosure, I might try that for a next version.

@SianaGearz 23 дня назад

Here's a silly thought. If you're building a sim shifter and are going to have a microcontroller in the knob, and if you're building your own shifter using hollow 10mm tubing, you can connect it to the master microcontroller (the one that does USB and position readings) with a mini-XLR connector, used as both quick release mechanical and electric connection. It can even be done with mere 3 pin connector, with gnd, vcc and data with data being either mono directional UART or bidirectional OneWire. I think bidirectional UART can work as well, if initially and after every transmission you HiZ (disable) the TX pin on the corresponding microcontroller, then connect all the RX and TX lines together via 1K resistors. You also need a robust M/S distinction where the S will only send in reply to M via polling, because you have no collision handling. Other connector pin counts are available as well, up to 6, to make life less difficult.

Need something similar to this for an ev project, keeping the old shifter and changing it to instead shift between drive modes (PRND, performance, range, normal) The idea of a pcb holding all the hall effect sensors is perfect, i was gonna mount some jank big hall effect clunkee sensors but this is waaaaaay cleaner

One trick I've found with these small OLED displays is that they have a very high refresh rate. High enough that you can blink the pixels quickly and rely on persistence of vision to generate greyscale. I managed black, two levels of gray, and white for a game I made for the Arduboy.

@upir_upir 2 месяца назад

That´s interesting idea, but the UNO is not fast enough to update the display that fast. I might try this approach with ESP32, but I also have some OLED displays that support 16 grayscale values. I haven´t decided yet as to which display to choose..

This is pretty cool. How would you setup the hall sensors when the gear box is 6 speed and the R & 1 gears are right next to each other ? Or R and 3 in some cases.

@jebova2301 2 месяца назад

If I had to guess, I would assume you would want the sensors in the middle of the gears. For example, if your top row is R, 1, 3, 5 and your bottom row is just 2, 4, 6, you would put a sensor between R and 1(sensor1), another sensor between 3 and 5(sensor3), then a sensor between 4 and 6(sensor4), and the final sensor to the left of 2(sensor2). Logic would be along the lines of "if sensor1 is a high value and sensor3 is no value, reverse. If sensor1 has high value and sensor3 has low value, 1st gear. If sensor2 has high value and sensor4 has no value, 2nd gear. If sensor1 has low value and sensor3 has high value, 3rd gear. If sensor2 has low value and sensor4 has high value, 4th gear. If sensor1 has no value and sensor3 has high value, 5th gear. If sensor2 has no value and sensor4 has high value, 6th gear. In that case, you would need to test it and observe the values reported in each position. "No value" wouldn't necessarily mean 0, but just a value that is significantly below the "low value" amount when in a position where it would be utilizing values from both sensors. That's just a rough idea at about 5 in the morning, though. Obviously it would take a little trial and error figuring out what values are being returned.

@BeatTheD3viL 2 месяца назад

@jebova2301 I had another idea of using the 12v signal from built in reverse trigger.

@upir_upir 2 месяца назад

There is always some movement between reverse and first gear, even when it feels in the same position. You should be able to differentiate between those with more hall sensors.

Nice project !! What about to implement a buzzer to advertise RPM below or above ?? This would be very useful. I used to read this singnal in the center pin of the distributor, hi voltage cable... just 3 or 4 turns of AWG22 and rectify with signal diodes to get the frequency. This is direct proportional to engine RPM... and cheap than use OBD...

Thank you for an excellent narration style. If we connect the ardino to the pc in this state, will it work in games?

@upir_upir 2 месяца назад

Thank you for your comment, I´m glad you like it! As for your question, the asnwer is yes, you can connect this directly to your PC and use that as a controller. The only requirement is to use an Arduino that could be used as an USB device - for example Arduino Leonardo. The connections and the sketch would be exactly the same, except now the Arduino would act as a keyboard/mouse/controller, and you can use it to play games. That said, the shifter when not connected to transmission will not stay in gears, so some adjustments to the actual hardware would be needed..

@@upir_upir I believe it would because the accelerometer under severe acceleration would go over the 1G mark in certain axis, so that can be addressed in the code and based off placement you should see only certain pre determined values.
