Just a couple of rainbow shield examples that will randomly light up the various LEDs with different colours [codesyntax lang=”cpp”] #include <Rainbowduino.h> void setup() { Rb.init(); } unsigned char…
The BMP180 is a new digital barometric pressure sensor of Bosch Sensortec, with a very high performance, which enables applications in advanced mobile devices, such as smart phones, tablet PCs…
The SHT21 has a capacitive sensor element to measure humidity, while the temperature is measured by a band gap sensor. Both sensors are seamlessly coupled to a 14-bit ADC, which then…
The MQ-2 is a fairly low cost sensor that can detect LPG, i-butane, propane, methane ,alcohol, Hydrogen, smoke. There are a wide variety of shields and modules that can be bought…
This example will read the temperature using the built in temperature sensor on the Arduino Esplora and display it on the LCD Code [codesyntax lang=”cpp”] #include <Esplora.h> #include <TFT.h>…
Recently I had problems getting my Arduino and ethernet shield working correctly, I found the following code which basically reports via the serial monitor whether the SD card is available…
I had one of the Rainbowduino/ColorDuino type shields in my box of parts, so I decided to throw up a quick example. The Rainbowduino can be use to drive 8×8…
In this example we connect a 16×2 LCD with an I2C backpack, this backpack allows us to only use 2 pins to connect our LCD to an Arduino, so if…
