Sample 8
This sample demonstrates how to
control the direction of a DC
motor using 2 relays. Braking is
accomplished by connecting both
motor terminals to a common
power connection (Faraday’s
Law). The capacitors shown may
not be required for small motors,
but if you experience problems
with relays shutting themselves
off, the inductions suppression
capacitor will be required. The .1uF capacitor helps suppress electronic noise if
the battery were to be used by sensitive devices (such as radios/amplifiers).
