Volume Meter can be considered as an Equalizer, in which LEDs will glow according to the intensity of the music. If music is loud then more LEDs will glow and if music is low then lesser number of LEDs will glow. Volume Meter (VU) is an indicator or representation of the intensity of sound level over LEDs and can also serve as a volume measurement device.
In this Project, we are building **VU M...
AC Fan Seed Controller with DHT22 (or DHT11) Temp sensor and LCD Display of Temp. UART or I2C options for 16x2 LCD diplay shown. Uses External 240V to 12V DC PSU to provide power to the Arduino Vin pin and the 5V output from the Arduino to provide power for the DHT22 and ZC Probe.
## Arduino drive the temperature and humidity sensor DHT11 ##
Available as both a plain component or an Electronic Brick.

## 10k pullup resistor needed ##
Needs 4.7K to 10K pullup resistor from +5V to Signal pin. Connect to Arduino MEGA 2560 Digital pin 3, not Analog pin.: When the connecting cable is shorter than 20...
## Arduino drives A single wire digital temperature sensor ##
DS18B20 fromMaxim (formerly Dallas) is a great chip to measure temperature in your project. Fortunately, the Dallas emperature library which makes use of the sensor is easy to Arduino.
In the latest version of the library can be found here
We used version 3.6...
## Arduino drive a LED blinkling ##
A light-emitting LED, a resistor. With hardware devices after (on-board resources), you need to install the software Arduino IDE (Integrated Development Environment) on your computer. In addition, you need to install on your computer and configure your Arduino board (by installing the device driver).
