This is a 3-wire Serial LCD Module example connected to an Arduino uno, I bought this as part of a kit there was an Arduino Uno and a couple of different LCDs but I always had trouble getting this one working. Its …

In this example I added an onboard 5v regulator and electrolytic capacitors to the existing no PSU design Assembly List Label Part Type Properties C1 Ceramic Capacitor package 200 mil [THT, multilayer]; capacitance 22pF; voltage 6.3V C2 Ceramic Capacitor package …

More info on the Arduino Yun can be found at the http://arduino.cc/en/Main/ArduinoBoardYun?from=Products.ArduinoYUN Arduino Yun pinout This is a fantastic pinout, I advise you to visit the site listed in the image and purchase the book with the pinouts Arduino Yun …

In this example I connect a TTP224 4-CHANNEL CAPACITIVE TOUCH module that I bought recently to an Arduino. This capacitive module offers 4 touch pads, here is a picture of this   Schematic We connect the 4 outputs to Arduino …

Recently I purchased a bunch of Arduino Nano clones that were labelled as DCCduino.Lets look at the board I decided to give one of these try, plugged it in and the device was unrecognised in Windows, I use Windows 7 …

In this example we connect a DHT11 sensor our Arduino, again we will display the temperature and this time the humidity as well on our LCD4884 shield. In this example we connected the data pin of the DHT11 to Pin …

In this example we connect an LCD4884 shield to our Arduino and then we connect a DS18B20 temperature sensor to Pin 9 and we will display the temperature in celsius and fahrenheit. Code Here is the code You need to …

A simple example to count to 10000 and display this on an LCD4884 shield Code [c] #include “LCD4884.h” #define MENU_X  10      // 0-83 #define MENU_Y  1       // 0-5 int counter = 0; char string[10]; void setup() { lcd.LCD_init(); lcd.LCD_clear(); init_MENU(); …

In this example we will connect a 7 segment display to an Arduino Schematic Code [c] const int  A = 4; const int  B = 5; const int  C = 6; const int  D = 7; const int  E = …

In this example we connect an LDR to analog 0 and depending on the value read in we then vary the brightness of an LED connected to Pin 9 using PWM. The input read from the analog pins will be …

A keypad is a nice simple method of accepting user input into your project. These come in a number of styles and generally there are 2 types a 3×4 keypad and a 4×4 keypad. The numbers stand for the rows …

Another TM1638 example, this time when you press a button a random sequence of LEDs will be lit The previous project is here for connection information Code [c] #include <TM1638.h> // define a module on data pin 8, clock pin …
