The HDC1000 is a digital humidity sensor with integrated temperature sensor that provides excellent measurement accuracy at very low power. The device measures humidity based on a novel capacitive sensor. The humidity and temperature sensors are factory calibrated. The sensing …

In this example we use an Arduino Esplora nad use the on board micropone and RGB led and create a sound level project, if the sound level is an acceptable level then the RGB led will be green, if the …

In this example we will create a Magic 8-ball using an Arduino Uno and an LCD keypad shield, when one of the buttons is pressed a random message will be displayed. The Magic 8 Ball is a toy used for …

The bar graph is basically a series of LEDs in a line, this is a common hardware display for analog sensors. It’s made up of a series of LEDs in a row, you simply treat these as you would do …

This example was just a modification our LM35 sensor example at http://www.arduinolearning.com/code/lm35-temperature-sensor.php. This time we will create an app to read the value sent rather than using the serial monitor. Arduino Code Slight change in that we removed some of the …

In this example we will connect an RGB LED to our Arduino and control it via a C# winforms app that will send commands down to the Arduino via the com port. In this example we keep the commands very …

In this example we will connect an LM35 temperature sensor to our Arduino The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The LM35 thus has an advantage over linear …

On one of my recent visits to an electronics website I saw this voltage sensor, intrigued I bought it and wondered how it worked, there didn’t seem much to it. As an Arduino is limited to 5v maximum on its …
