The Ultimate 555 Tester

An integrated circuit that is often used in hobbyist circuits is the venerable 555 timer. This little IC is used for many devices involving timing of all sorts, and is also used as an oscillator that can go from very low frequencies to a few hundred kilohertz. Here is a little device that can help remove any doubts when a 555 circuit does not work, a device that will help you figure out if the 555 is broken, or if the circuit was not assembled correctly. In other words, a 555 tester.
