The concept of this kit is simple and straight forward. The core of the
system is the IC U1, a 16F628 PIC microcontroller.
We have selected this processor because of the available in- and
outputs. The number of in- and outputs is convenient for our purpose
and, in addition, it features a serial interface.
We have pre-programmed the IC in such a way that it can process all
commands we send through the serial interface. Moreover, the proces-
sor can drive the Transistor switches and monitor the optocoupler input.
When a robot arm motor is activated by a transistor a red or green LED
will light up.
IC U1 (MAX232) handles the level change of the TTL and RS232
signals. The optocoupler IC U2 is required for galvanic seperation of
the sensitive circuitry from the inputs.
You can also completely reset the system at any time via the reset
switch.
When the kit receives data from the PC, the “Data” LED light up.
