Sometimes in embedded design you may want to go wireless. Might be you will want to log various readings of remotely placed sensors, or simply build a remote control for robot or car alarm system. Radio communications between two AVR microcontrollers can be easy when specialized modules are used. Lets try to run very well

Introduction The goal of our project was to develop a remote control whose buttons would be readily programmable by recording the signal from another remote control. After revising several standards on infrared signals, we determined that the approach to take was to record the signal by determining the width of the transitions in the waveform,

Concept The customer’s demands were to develop and build a kit, consisting of a small mechatronic system with educational concept. In particular, he asked for a driverless robot for training purposes abroad. The idea behind this is that our customer needs a kit for sending it to partner schools around the world to help the

Introduction With this circuit we can control up to 8 devices (4 devices in our example project), by sending a specific SMS message with any mobile phone. It’s very useful in the case that, at the place we have the devices, we have not a wired (fixed) telephone line. If you have an old ericsson mobile phone

Introduction How many times you needed some remote control to handle some electric device ? Many times. There are lot of remote controls like infrared, RF, SMS (like my other circuit) and more. The basic small-range remote controls are 2, Infrared and RF (Radio Frequency). One of the weaks of Infrared is that the signal
