• 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 …

  • 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 …
