This Project was inspired by Paul Carlson’s Video on how to test a relay using a pulse generator and a curve-tracing oscilloscope. The 9V Pulser is a simple circuit which uses a 555 timer to let an LED blink, very similar to what is shown in Chris Gammell’s Getting to Blinky series of videos. An additional load like a relay is attached in parallel to the LED, which then acts as an indicator of the pulses going into the load.
The load and the LED are not directly driven from the 555 timer but from the 9V battery itself. The 555 timer just activates a transistor which switches the power to the load and the LED on and off.
