This example code is in the public domain. LCD D5 pin to digital pin 4 // change this to any digital pin you have left with no connection i used pin 6.LCD Enable pin to digital pin 11 // change this to any digital pin you have left with no connection i used pin 7.LCD RS pin to digital pin 12 // change this to any digital pin you have left with no connection i used pin 8.The SD library makes initialization, reading, and writing of the card very easy. An major advantage of the module is that it can be used with the SD library that comes with the Arduino IDE. This sketch prints “Hello World!” to the LCD In this tutorial, it is shown how to read and write SD cards utilizing the MicroSD Card Adapter module and Arduino Uno. There are many of them out there, and youĬan usually tell them by the 16-pin interface. Library works with all LCD displays that are compatible with the SOLUTION : edit liquid crystal example in arduino IDE. PROBLEM WAS : both uses pin 4, pin 11, pin 12 same time. Īnd the LCD uses below pins and what I did was I changed them. SD CARD MODULE USES below pins and I think we should not change them. Usually, the maximum identifiable capacity of these modules is 2GB for SD cards, and 16GB for micro SD cards. NoteThese modules can not handle high-capacity memory cards. This library is installed on the Arduino application by default. If there are newbies like me looking for help on this what i did was , To use these modules with Arduino you need the SD library. It was really a simple edit I needed to do, but of course I figured that out after the explanation by. The Nano is made for breadboard use and features soldered headers for all pins, allowing to attach the board easily on any breadboard. With a length of 45 mm and a width of 18 mm the Nano is Arduino's smallest board and weighs only 7 grams. Reference to Hobb圜 in your comments if you redistribute this code. The ATMega328 CPU runs with 16 MHz and features 32 KB of Flash Memory (of which 2 KB used by bootloader). If you have a Mega, the pins are different You’ll want to use digital 50 (MISO), 51 (MOSI), 52 (SCK), and 53 (SS). Usually this is pin 10 but you can actually use any pin you like. You will also need a fourth pin for the ‘chip/slave select’ (SS) line. You may copy, alter and reuse this code in any way you like but please leave For Arduino boards such as the UNO/Nano those pins are digital 13 (SCK), 12 (MISO) and 11 (MOSI). So I have the LCD and SD CARD MODULE but my problem is both modules use the same pins ( pin 11, pin 12, pin 4 ) ?Īccording to arduino site, the pin configuration for LCD is as below ,Īccording to SD CARD MODULE site, the pin configuration for SDCARD MODULE is as below , But i haven’t tried connecting both at same time as I have a problem. I tested the circuit with ONLY with the SD CARD MODULE and another time ONLY with the LCD MODULE. Also making a data log into a SD card is essential. Basically the sensed voltage / current is to be shown in a 16x2 LCD. My project is a simple voltage / current monitor device with ACS 758 sensor. txt files on an SD card.First, I’m a newbie to arduino so any help is highly appreciated ! The following image of the OLED shows the values recorded by the Power Logger. I was later able to extract the data from my SD card and graph it. This is why I ended up creating a power logger that recorded the voltage current and power produced onto an external SD card. I needed to create a device that would allow me to collect the data I needed. Because I didn't have access to an oscilloscope and it wasn't feasible for me to record data for all the sets of solar panels at the same time throughout the day. This allows the recorded data to be graphed and analyzed for your own purpose.įor one of my research projects, I needed a way to be able to record the voltage current and power produced by different sets of Solar Panels throughout the day. This device acts as a multimeter which stores the recorded data values on an SD card. NOTE: This project was completed in 2019 as a part of my science fair project
