Purpose: To verify the functioning of a servomotor for three standard pulses by designing the related hard-
ware and software and conducting experiments thereafter.
Problem
Prepare a hardware circuit to interface a servomotor and three keys with 8051. Develop a software so that
each key, when pressed and released, would generate only one pulse. e durations of pulses should be 1, 1.5
and 2 milliseconds, respectively, for keys K1, K2 and K3.
Solution
A circuit to meet above specifi cations would consist of three keys, one servomotor properly interfaced and
the reset circuit for the 8051-based ...
