Hi I have question, Arduino Uno R3 - Power pin (5V) from this single point I can take power for LCD & Hall Effect sensor? Hall sensor from hifi heaven need 5V or 3.3V? Thanks Raj
Yes, the sensor runs from 5VDC.
Sorry to inform late that I've been hospitalized for a intestinal growth already removed. I'm not able to help further. Sorry again.
To Coolmaster, Thanks lot, you given idea build cool Midas tachometer, Mr. Bill helped me to complete my Midas tachometer. Please take care your heath.
To Bill, thanks lot. Rajkumar
To Bill, thanks lot. Rajkumar
Hi find my tachometer completed, I have ordered ZeroZone linear power supply for my turntable motor, I build my tachometer (Midas LCD+ Arduino Uno) inside linear power supply. Thank you all helping build accurate turntable tachometer. Rajkumar

Great looking build; glad it worked out. The table looks great and appears to be very accurate.
Thanks Bill, this table originally direct drive, I have modified 2 in 1 direct belt drive. There was sound different in belt and direct. When I build belt drive never use direct. I love to listen belt drive. Rajkumar

That is a nice looking isolated motor housing, good job
Not trying to hijack the thread.
I just checked HiFi Heaven website to purchase another of the sensor module.
Glad to see they are still around.
I will however say, it is sad to see the Roadrunner and the Falcon still listed but, unavailable.
Glad I have them in my system.

I have been following this thread with great interest . Really great to see this come together and brilliant of Pyramid to share his code & expertise . I've built an RG4 so now on to this 🙂
I've got the Arduino , OSHPark Sensor PCB's (which I am just building) . and am about to buy these displays
MUZOCT IIC/I2C/TWI 1602 Serial Blue Backlight LCD Module for Arduino UNO R3 MEGA2560: Amazon.co.uk: Computers & Accessories
Do they look about right ? I just need to add that display type to the code ?
Thanks all

@raymondo- It's I2C so it should work, you just have to make sure you have the right address (use the Scanner script in post #307 to find the address if in doubt) and it doesn't need a negative supply like the Midas module; if it does, you will need to mod the display.
thanks bill - i'll order and give it a go . modification is no problem if needed - is there an easy way to spot if it needs a -ve supply?
An indication would be lack of range in contrast control. I was surprised to learn the Midas display needed this; usually it is only needed for extended temp operation.
ok great thanks bill - everything is ordered so I will give it a go in the next few days. do i need to do something to the line
LiquidCrystal_PCF8574 lcd(0x3f);
in the code once I have my display apart from change the address to whatever mine uses?

Hi,
I think for that type of display with the I2C adapter installed you need to do like this.
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x27, 16, 2)
The second line you must set the address that it maybe Ox27 or 0x3F. and how many characters and how many lines.

thanks a lot - as soon as the kit lands i will build it and report back .
Ok so I've got the display working and tested with a hello world sketch
But when I try and complile the tach ino i get this error
Using library LiquidCrystal_I2C-1.1.2 at version 1.1.2 in folder: C:\Users\braymond\Documents\Arduino\libraries\LiquidCrystal_I2C-1.1.2
exit status 1
expected ',' or ';' before 'const'
The line highlighted is the first one
const int TRIGGER=3; //* input on PB3
I'd post a screenshot but cant work out how to do that !
Any ideas ?
Thanks

Did you copy tach.ino from a file or from a screen shot here on DIYAudio. The screen shots will randomly omit characters.
The error may be at the end of the previous line; is there a semi-colon after the lcd declaration:
LiquidCrystal_PCF8574 lcd(0x3f);

you were right it now looks like this
LiquidCrystal_I2C lcd(0x27, 16, 2);
and compiles and uploads fine - but - nothing happens . I've not got the sensor built yet but figured it would still display something .
so for example if im running the hello world scrolling program and then upload the tach one it uploads but the display freezes and then nothing happens . It is definitely uploading fine.....
