[image] vikramjeetagam: This meter has 12 pin custom LCD. Examine the TDS meter and the LCD for all kinds of type-numbers. Search for usermanuals and datasheets with these numbers. Finding the datasheet of the LCD will save you between 50 and 500 hours of analysing which pin of the 12 pins …

I am a beginner in this field and working on a hydrophobics project. I want to develop a DIY hydroponics automation system usin Arduino or NODE MCU. [20230827_162204] This is the image of Tds meter pcb it has main ic with no any specification and another 8 pin ic having marking ATMLH904

There is this sniffer: [image] LCD 1602 (and similar) databus sniffer Exhibition / Gallery This is a basic sketch to demonstrate sniffing the data bus of an LCD 1602 display to interpret the contents of the display. This could be useful if, for instance, you are using a 3r…

Sir The circuit under question has a 12 pin lcd without any specification and pin description. On one side of pcb where lcd mounted P1 is written. So how to recognise pins.

[image] vikramjeetagam: So how to recognise pins. If you have no datasheet the left way to find out what pin is what will be by doing hours long tests using a 24 MHz 8 channel logic analyser to find out: which pin might be a clock signal which pins might be the datasignals. After having f…

[IMG_1195] Sir the lcd under discussion may be similar to this. Kindly check it

[image] vikramjeetagam: Kindly check it I checked it. Number of columms (12) is equal to the number of pins (12) as you described. I'm sorry not more checking possible as I don't have your LCD lying on the table. Any deeper checking would be similar to make you a very detailed list breath…
