Proteus simulation of a digital clock with hours/minutes/seconds setting buttons implemented with 74LS160 4-bit binary counters, 74LS21 dual 4-input AND gates, and CD4069 inverter circuits.
A distance measuring sensor is mounted on a RC servo motor. a microncontroller PIC 18F458 drives the servo motor turning the IR sensor for a scan of 180 degrees. The sensor generates a voltage proportional to the distance to the measured object. The PIC measures the voltage and draw a radar screen on the LCD display.
