The Arduino Weather Station / Thermostat using ATmega328 microcontroller

I've always been interested in monitoring my local weather, and noticed the difference between what weather.com and accuweather.com think my local weather is, and what I see out the window. I also wanted better control over my heating and A/C system. As a computer and electronics nut, I've been playing with the Arduino Microcontroller, and decided to to meld my interests. So here goes the documentation on m ...

Temperature Control For Kitchen Appliances

In this Instructable, I will step through controlling the temperature of most kitchen appliances. As an example, I will use an old Westbend Poppery popcorn maker (aka. coffee roaster), but these same techniques will be applicable to most hot plates, coffee makers, and waffle irons. This instructable puts you at risk of electrocuting or burning yourself. I will do my best to point out potential pitfalls, but ...

Numitron clock & thermometer using Microcontroller atmega48

I really like nixie and numitron clocks, but I never worked with them before. So I decided to give it a go. I choose numitrons because of 2 reasons: first of all nixies need a higher voltage than numitrons to work. Nixies need around 170V DC and numitrons only 4,5V so they are safer to work with and don't need a special powersupply. The timekeeping is done by a ds1307 I2C realtime clock and the temperature ...

DS1820 Temperature Controller using atmega8515 microcontroller

This project displays the temperature on an LCD display with an resolution of 0.06degrees. DS1820 is used for sensing the temperature. It can measure temperature range from -55deg to +125deg. But i take care of only the possitive temperature. There are 3 switches to change the alarm temperature, the user can increment the Alarm temperature by pressing the UP button and they can decrease the Alarm temperatur ...
