From DIP, rotary DIP, and slide switches to tactile, rocker, push button, and toggle switches, there is a nearly limitless range of mechanical switches differing in size, shape, interfaces, and features. Although a relatively basic component in electronic design, each switch type has its benefits, drawbacks, and ideal use cases. Because all switches serve a…
Insight – How DIP Switch works
DIP switch can be defined as an array of simple two terminal On-Off electromechanical switches (Single Pole Single Throw) that are commonly used in electricity operations. The word DIP is an acronym for Dual In-line Package which means that the electrical contacts are in two rows. DIP switches are surface mountable and are used in those applications where multiple numbers of switches are involved in output generation. For instance, in a universal remote control, the DIP switch is used to set the frequency according to the device that is being operated. On a computer motherboard, DIP switches help in optimizing the clock speed and configuration settings according to the type of processor mounted.
555 Timer IC Tester
The NE555 timer IC is 8 pin DIP which performs a number of tasks in electronic circuitry. It is becoming very much popular among hobbyist as there is a huge list of circuits and experiments which can be performed using it. This project helps to test whether a 555 timer IC is properly functional or not.This IC testing circuit can test any of the 555 timer IC. This is done by testing whether it is oscillating or not. By using this tester it can be immediately tested whether the timer is functional or not. It also tells if it is shorted or oscillating. If both the LEDs are flashing, the timer is in good working condition and if both the LEDs are OFF or on solid then it is defective. It can also be used as a trouble shooter in 555 based circuits. In this project the IC is wired in the astable multivibrator mode. When the power is supplied, the LEDs starts flashing which shows IC is in good working condition.
