Counter timer VSM module in Proteus used to measure frequency of 555 timer IC

Hello friends, this is another Proteus simulation project. This is about the VSM Counter Timer module available in Proteus simulation  Software. You can see in the schematic below that a 555 timer IC is used in Astable Multivibrator mode to generate square wave of different frequencies, value of frequency can be changed by changing the value […]

What is Reed Switch?

What is Reed Switch? How does a Reed Switch work? Reed switches are very similar to relays, except a permanent magnet is used instead of a wire coil. When the magnet is far away the switch is open, but when the magnet is brought near the switch is closed. These are very inexpensive. With this device the […]
