Working with the 555 555 is used for producing a clock (square wave) at a desired frequency. It can be used in various ways like the astable mode‚ monostable mode etc. Here‚ we deal with the astable operation of 555. Astable mode ensures that the 555 is self-triggered & so‚ it acts as a multi-vibrator. Let us look into the working of 555 in astable mode: These are the connections needed to make the 555 chip run in the ‘astable’ mode. The pin numbers are given in circles. Note the

description of Electric Iron introduction: An electric iron is a small appliance‚a handheld piece of equipment with a flat‚ roughly triangular metal surface that‚ when heated‚ is used to press clothes to remove creases. Ironing works by loosening the ties between the long chains of molecules that exist in polymer fiber materials.
