The Smart Whole Home Information Awareness Will Keep Your Home Warm!

Some of the household is equipped with heating system to keep the whole house warmer, especially during the cold season. However, when the home get bigger, then it’s harder for the users to balance the heating system. Yeah, you might choose to close and open ventilation systems from time to time, but don’t you think it’s a very hassle, when you have to do it repeatedly? Get the rid of the trouble, by simply developing a “whole home information awareness” device. Well, this whole home information awareness device is actually an Arduino controller, which is monitoring sensors in all areas of the house. This is how the device works: At a high level, there’s a microcontroller in each room. When the temperature or humidity sensors reached a certain level, it instructs the microcontroller to open and close the ventilation in a specific way. The main objective of this device is that no room will be more than 1.5 degrees and 5% relative humidity different from any other room. This means, there’s no more hot guest bedroom or cold living room… Continue reading

The Combination of Laser Modem with an Arduino Microcontroller

Can you ever imagine that what is the combination of laser modem and Arduino microcontroller looks like? Well, you might think that it will be a hard task and requires many complicated steps to get these two different components assembled, but it is easier than you’re thinking of… Let’s cut the long story short and get this project started right away… You’ll need to apply the serial data transition from an Arduino controller using a standard red laser, photo transistor and an instrumentation amplifier. Before that, please do make sure that you’ve ordered an IR LED and phototransistor pair from the local electronic store with some spare ATMega168 microcontrollers. After that, is time to start the first experiment by simply using the IR LED to transmit 2400 baud serial to the phototransistor. Therefore, you have to program the Arduino Diecimilia with the sample serial program, which it’s altering the baud rate and will allow it to run in a continuous loop! This is surely an interesting and challenging project, hope you all will enjoy it and having fun with it! Continue reading
