  1. How is the current generated? The current is generated because of the positive and negative charges. The electrons are inside the metal conductor and actually flow from the negative electrode to the positive electrode. It can be imagined that there is a positive charge on the positive side of the power supply. Inside the metal conductor, the nucleus has little force on the electrons, and the electrons are easily separated from the nucleus. So the electrons in the metal conductor close to the positive electrode of the power source are first attracted by the positive charge of the positive elect
  2. The 555 timer is a medium-sized integrated circuit developed by Signetics in 1972 to replace mechanical timers. It is named after the input is designed with three 5kΩ resistors. This circuit later became popular in the world. At present, there are four popular products: two BJTs: 555, 556 (with two 555); two CMOS: 7555, 7556 (containing two 7555). The 555 Timer is a mid-scale integrated device that combines analog and digital functions. It is called 555, which is usually fabricated by bipolar (TTL) process. It is called 7555 by complementary metal oxide (CMOS) process. In addition
