What is an Industrial limit switch?

What is an industrial limit switch? The standard limit switch is a mechanical device that uses physical contact to detect the presence of an object (target). (opposite to Proximity sensors) When the target comes in contact with the actuator, the actuator is rotated from its normal position to the operating position. This mechanical operation activates contacts within the switch body. […]

What is PLC?

What is PLC? Control engineering has evolved over time. In the past humans were the main method for controlling a system. More recently electricity has been used for control and early electrical control was based on relays. These relays allow power to be switched on and off without a mechanical switch. It is common to use relays to […]

Speaker interfacing with 555 Proteus simulation

Hello Friends we are back with another proteus simulation. This is buzzer interfacing with 555 timer proteus simulation. Here a simple Astable multivibrator circuit is made with 555 timer IC and the output is given to the speaker. the frequency of sound is generated from the help of capacitor C2 and pot RV1 we can […]
