Introduction: Application Board of 555 Timer IC
The 555 timer IC is the one of the most useful and well known IC for everyone of us. My professional embedded Hardware carrier start two years back and in 2019 one my resolution is to prepare 45 different circuit using 555 timer IC for understanding the different [suggested By Team Leader :)]. I stated to work on it and by different resource available on internet specially by www.circuitstoday.com , www.circuitstoday.com and Texas Instrument I manged to learn about the 555 Timer IC and Understand the different concept related to time.
In this Instructable I am sharing different Eight application circuit of 555 Timer IC with some new approach. I prepared the Eagle Schematic and Layout Design with keeping the delivery of full understanding of 555 Timer IC with single standalone board.
So in the above design I have included the following circuit with Some information of 555 Timer IC and its Pin Configuration details. Also one 8 contact DIP switch is available to enable individual circuit where the basic information about the each application is available just below the circuit. Also I kept provision of pinhead and wire connector for testing output on different instruments.
Following are the Application circuit available on the Board:
1. Astable Multivibrator
2. Monostable Multivibrator
3. Bistable Multivibrator
4. LED Dimmer using PWM
5. Delay Generator before Turn ON
6. Servo Motor Driver
7. BJT Transistor Testing Circuit
8. Single Digit Counter
I hope all you will like my new approach for these 555 Timer IC Application Board where I always open for the suggestion from all you Techies.
