This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno clones, has within it a watchdog timer that clicks over at a rate of ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

You'll need an Arduino along with a bunch of various sensors to get the project rolling, and once it's all set up you'll have a simple, but cheap system to monitor your home. Head over to ...

I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

A programmable temperature and process controller for use by the maker community has been designed to be Arduino-compatible. Called the SmartPID it can be programmed on a PC via the USB port using the ...

Using motion detectors and an Arduino you can trigger lights, fans, or even an pneumatically controlled cleaver-wielding clown to help add your house to the “if you dare” list. There are ...

When you think of Arduino projects, your mind likely goes straight to RFID door locks, weather sensors, or automated plant watering systems. While these are undeniably pretty cool projects, you ...

Programmer Mike Tsao has devised a clever method to program an Arduino board using sound. It’s called TribeDuino, and it uses the Arduino’s audio sensors to detect the time elapsed between ...

Users will need to provide their own Arduino Pro Mini and the hardware features a 1.4 W, 8 Ohms, Texas Instruments TPA2005D1, 14 bit ganged PWM, PWM 8 kHz low pass smoothing filter all powered by ...

Enclosed are the ultrasonic sensor, a temperature sensor and an LED indicating the power status. On the other side of the CAT5 cable can be found an Arduino compatible board with an XBee shield ...
