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.
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

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

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.....
