You need to download and LCD Assistant , now create a 84 x 48 pixel bitmap using a drawing program. I used Paint.net for windows to create this image Import this into LCD Assistant and save the output, this then is pasted …

In a previous example, we did a basic copy of the Arduino capacitance shield but hey outputting to the Serial Monitor is a bit boring, so how about we pick an LCD or LCD shield to try this out with. …

I fancied trying the https://www.arduino.cc/en/Tutorial/CapacitanceMeter , to look at the theory visit that page. I was wanting to see how accurate this is and also wanted to test this on other variants such as the Chipkit and the MSP_EXP430G2 to …

This was an app that interested me as it actually gives you the Arduino IDE on your Android device, so obviously a tablet is way better than a phone. One slight problem as the developer explains is that the app …

The Arduino Companion is an Android app which has been designed to help anyone getting into Arduino and electronics. The app contains the full Arduino Reference for offline use, as well as a very useful resistor calculator.   As well as …

The MQ-2 gas sensor module is suitable for detecting LPG, i-butane, propane, methane ,alcohol, Hydrogen, smoke. Code In this example we simply connect the AOUT to Analog pin 0 and read in the value and output this via the serial monitor …

Another example for the Arduino Esplora, we will read the value from the slider and play a tone based on that from the buzzer. You can see the location of these parts in the picture of the Esplora underneath This …

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 …
