Objectives of this experiment: This trainer uses a 555 timer to power an ultra bright LED. The output is a pulsating red light that can be projected using lenses. An ultra bright LED capable of 300 mA output is tied to pin 3 of the 555 timer. This IC is configured as an Astable multivibrator mode. This frequency is controlled by RC values. By adjusting P1 the frequency varies. The control changes the output from a slow blinking to fast pulsating light. This operates on 9V dc. This trainer precisely demonstrates this principle and operates on 9V DC
