A simple clock simulation for Simplescratch There is a timing loop that puts out a message once per second. Each hand is set up to move the appropriate number of degrees per second: Second Hand: 360 deg/60 sec = 6 deg/sec Minute Hand: 360 deg/[(60 min)(60 sec/min) ] = 0.1 deg/sec Hour Hand: 360 deg/[(12 hr)(60 min/hr)(60 sec/min)] = 0.0083333 deg/sec The remaining code handles the setting of the clock.
