Temperature and Humidity sensor using Arduino display on I2C 16X2 LCD Library download link -  https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads NOTE: Some of this type board come with the A0 A1 A2 connections (See photo) that are NOT bridged with solder as in the photo. Those will have address 0x27 not address 0x20. For that version you need to change the sketch example below. LiquidCrystal_I2C lcd(0x20, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE); MUST BE CHANGED TO: LiquidCrystal_I2C lcd(0x27, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE); Completed project Schematics A quick video Code -  #include <dht.h> #include <Wire.h> #include <LCD.h> #include <LiquidCrystal_I2C.h> LiquidCrystal_I2C lcd(0x20, 2, 1, 0, 4, 5, 6, 7, 3, POSITIVE); // Addr, En, Rw, Rs, d4, d5, d6, d7, backlighpin, polarity #define dht_dpin A0 //no ; here. Set equal to channel sensor is on dht DHT; void setup(){   Serial.begin(9600

Simple LED memory game - (also known as Repeat after me!) LEDs light up with corresponding musical notes in a randomized sequence. Press the buttons in the same sequence to win a round. Starting difficulty level is configurable, as is the number of rounds you win before the difficulty level increases.
