The
remote controlled procesess are needed because in some applications, the
presence of the human is not possible or is not allowed. The control signals
are generated by a remote controll. An infra-red decoder, SFH506, transmits
signals to a microcontroller which, based
on the software inscribed, makes interpretation of the signals and
generates proper signals in order to actuate the process
As a controller we used a microcontroller from the AVR family, AT90S2313. These microcontrollers have Harvard architecture, with program memory and data memory. Most of instructions are executed in a single clock. The AVR microcontrollers include 83 instructions and 32 registers, all of them could be the accumulators. In the following figure is presented the electronic subsystem implemented. For programming the microcontroller we used the Bascom AVR software an extension of known QBasic for microcontrollers.
