Arduino from Scratch Digital Thermometer

I have loved making projects with Arduinos, but at $30 a piece your projects can get expensive. So I want to show you how you can make your own Arduino from scratch and save money doing it. Make your own Arduino for around $8. For this instructable I show you how to make one on a breadboard and with it make a digital thermometer. Step 1: Parts you need for the Arduino: Full Size Breadboard ($8 adafruit.com) ...

Arduino Esplora Temperature Sensor

This sketch shows you how to read the Esplora's temperature sensor. You can read the temperature sensor in Farhenheit or Celsius. Circuit Only your Arduino Esplora is needed for this example. Connect the Esplora to your computer with a USB cable and open the Arduino's Serial Monitor. Temperature to send data to your computer from the Esplora Code To send data to your computer, you need to open a serial conn ...

Multifunction Digital Thermometer using an Arduino

This instructable will show you how to create a multifunction platform with a thermometer, chronograph (count up timer), count down timer, and light display. It is also intended to be a platform for other analog sensors or any other functions you can think of. Multifunction_Digital_Thermometer.zip71 KB Step 1: Gather Materials To build the digital thermometer you will need: - Wire - Altoids tin - Breadboard ...

Smart Thermal + Arduino

Many times we are  faced with a heat containing coffee and don't  know if the fluid is at  the proper temperature and it is impossible to know just by looking at  the bottle ended up losing time with a coffee that is cold and we get  upset about it. This however  indicates maker by a graph LEDs if the liquid is hot, warm or cold. The LEDs gradually  connect the blue (cold) to red (hot), when there is a heat ...

House Temperature Monitor using Arduino

Recently a family member had his furnace fail while he was away from his house for a long period of time in the winter. His pipes burst and caused quite the mess. This project describes a temperature sensor that broadcasts the temperature in his house to the pachube data logging website. This allows him to check on his house from anywhere he has internet access. What is it? This project includes a temperatu ...

Temperature Displayed on 4 Digit 7 segment using Arduino

In this project I’ll display the temperature in a 4 digit 7 segment display (common anode). The sensor is the cheapest you can find so actually the temperature changes pretty easily which makes the display to show always different temperatures. But the idea is to apply this code to other projects with 7 segment displays that I might do later. if you want to learn a bit more of 7 segment displays you can rea ...

Temperature Sensor for Shower using Arduino

With this device you diminish the use of water in your house or work. Instead of waiting to see vapor in the shower to get in, this device help you to know when the water its at the temperature you want and you can instantly enter to the shower. In this way you don't waste the water by not knowing when its ready. This device shows the temperature of the water with a led bar (made from 10 leds). The leds get ...

Build a fully featured Arduino Thermostat

In this post I will attempt to describe the steps I took to build the arduino based thermostat shown in the following videos. The first video was taken when around just half of the coding of the menu system was complete, but gives you a basic run through of the features. This second video shows the completed thermostat with additional features implemented over the holidays, which includes a Total Heat Time ...

Arduino temperature controlled PC Fan

Oscar Gonzalez gives us a simple tutorial for speed controlling a PC FAN and reading a LM35 temperature sensor with an Arduino microcontroller. He covers the use of an optocoupler, PWM (Pulse Width Modulation) and reading analog voltages with the Arduino. He even has a video showing the fan speed control in action. This article was submitted by Oscar Gonzalez as part of the “Hobby parts for articles” progra ...
