PIC based IR receiving module

Chris from Pyroelectro have sent us hos latest project where he creates an Infrared receiver which is capable of receiving signals from TV remotes, decode them and then perform assigned tasks.

The heart of system is a PIC18F452 microcontroller which captures signals from IR Phototransistor. Along with full project, you can also find here a nice tutorial on Infrared theory and IR signals. So you can fully understand how your remote control transmits commands to TV or other controllable device. With IR signal receiver you can have more than enough channels to start controlling stuff around, the only limitation is that you have to see what you are controlling.

DIY Your Own Weather Station!

Do you have the interest to become an amateur meteorologist? Or, do you think that it’s impossible for you to be a meteorologist, since you didn’t have the basic knowledge about meteorologist?

Believe it or not, you don’t need to have the acquire knowledge for eligible yourself as an amateur meteorologist! All you need to do here is to construct your weather station inside a weatherproof box.


Have a closer look on the above weather station. This project is based on PIC18F452 that running at 4 MHz. It can displays auto-memory in all high and low values without any problem.

The reason why you should develop a weather station by your own, because it can be used to record:

  • Pressure reading,
  • Relative humidity,
  • Indoor and outdoor temperature display (Either in Celsius or Fahrenheit),
  • Mbar/hPa or mm Hg!

Beside that, it also included with calendar and clock, easy 3-button user-menu, 42 hour-history display and power saving sleep mode.

The best part about this weather station is it only turned on, when you’re really needed. Hence, you don’t need to waste many power consumption here!

The S.M.A.R.T. HVAC Monitor!

Many people always claimed how smart and intelligent they’re in electronics niche. If you’re one of those that have the talent, then would you dare try to create this S.M.A.R.T. HVAC monitor?

As it already mentioned earlier, HVAC monitor is a project that involved making an S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) Thermostat. It has the ability to access over the internet without any further modification!

Well, this project had already combined with several elements of embedded electronics, and it keeps on the theme of Home Automation.


By using the S.M.A.R.T. HVAC monitor, you’ll have the chance to control and monitoring the HVAC system via the web. Furthermore, it could be easily interface with most commercial and residential systems.

The project is based on a PIC18F452, where is capable of using the standard 2-wire hardware I2C. To be honest, you’ve to figure out the way overcome the small downside here, as these pins were not made available on the extension header, as the PIC-WEB uses I2C on-board to communicate with an EEPROM.

In overall, this S.M.A.R.T. HVAC monitor is a marvelous tool, and everyone should build one for himself/herself!

Don’t Be Menaced, You Wooden Menace!

Are you always fascinated about robotic arms and you’re wishing to build up your very own robotic arm? Well, if someone says that you can build an interactive robotic arm with only woods, then will you love to try it?

The main objective of this project is to develop a robotic arm, which can be used in most any direction like a humanoid arm. If you want to make this Wooden Menace a more useful, then you can adding a pair of grippers on the end. The grippers will be used to grip any trivial objects, such a piece of paper, pen, envelope, or any stationary items!

You can easily develop this project, as it is a simple design with a few moving parts. Thus, a PIC18F452 will be more than enough for it! This potentially limits the ability to control the arm with smooth movements.

Since this Wooden Menace robotic arm could be made out of generally cheap household items, the cost for creating this project won’t be too much.

So, if you’re curious about this Wooden Menace robotic arm project, then what are you waiting for? It’s time to create your own robotic arm!
