Convert an int to a string with base examples [cpp] void setup() { Serial.begin(9600); } void loop() { int i = 524; Serial.println(“String(i) = ” + String(i)); Serial.println(); Serial.println(“String(i, BIN) = ” + String(i, BIN)); Serial.println(“String(i, HEX) = ” + …

This example will display the temperature on an LCD connected to an Arduino Esplora Code [cpp] #include <Esplora.h> #include <TFT.h> #include <SPI.h> char tempCelsius[3]; char tempFahrenheit[3]; void setup() { //setup the LCD EsploraTFT.begin(); EsploraTFT.background(0,0,0); EsploraTFT.stroke(255,255,255); EsploraTFT.setTextSize(2); EsploraTFT.text(“Celsius”,0,0); EsploraTFT.text(“Fahrenheit”,0,60); } void …

In this example we will show a basic stepper motor example, we use a driver board that can be bought on many sites which basically comprises of a ULN2003 IC and a few other components, you can use either 5v …

The Rainbowduino can be use to drive 8×8 RGB Led Matrices or a 4x4x4 RGB LED Cube in common Anode mode. Its a nice board for practicing some programming skills, in particular loops. The example below shows some randomised colors Here …

I bought a low cost motor shield and a cheap micro servo on ebay, in this example I will show the parts I bought, how to connect them and show some basic code on how to drive the servo. Here …

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 …
