    Adjusting the speed of a motor or changing the brightness of a bulb can sometimes be a challenge without PWM. While a resistor can be used to reduce the current to such devices it results in large amounts of power dissipation as well as potential fire risks from the heat generator. The solution? Pulse Width Modulation! This kit will let you construct your very own pulse width modulation generator which can be used in many projects of your own!

    Nicely done. For future consideration, some early hobbyist servos had Vdd such that when a 3-pin connector is reversed, you destroyed the servo. Almost all hobby servos now have Vdd as the center pin, so they are relatively immune from connector polarity problems.
