This Transistor Flasher Kit by MitchElectronics will let you build a two-transistor flasher that flashes two LEDs similar to train crossing lights, excellent project for beginners and learners alike!
In electronics, it is sometimes required to have a signal that consistently creates a continuous pulse (like the second hand on a clock that ticks every second). Examples of where this would be useful would include:
A circuit that produces a pulse every so often is called an oscillator. Once powered, the output of an oscillator will turn on and then turn off. Once thiscycle has been completed it repeats itself indefinitely (so long as there is power). But how is an oscillator made? How do you get some componentsto keep on pulsing? In this kit, you will be creating a two-transistor oscillator that uses two transistors and a few other components to create anoscillator that generates a few pulses every second so that it flashes (that is why it is called a flasher).
