I've been working very hard to make electronic block tutorials for my youtube subscriberes, as well as potential buyers of my electronics learning board. The board has many different blocks, and there are 11x tutorial videos that I have to show you how each of them work. Each tutorial has a theory and lab section, so that the user can work through the theory, and witness the result! This is a VERY simple, and introductory circuit. The upcoming instructables will get more complicated, and MUCH more interesting!
This project is the first of twenty (Minimum) that this project board is capable of. You can take the tutorial information learned in this instructable, and put it to use on your breadboard! We will be discussing the 7805 5v regulator IC, the 555 Timer based monostable multivibrator circuit, and finally, a transistor based piezo buzzer driver circuit. By using these three blocks, you will be able to create a buzzer doorbell that is activated by a button. You can change the duration of the doorbell by adjusting the values of passive components (A resistor and a capacitor) on the 555 timer monostable circuit. Each clock listed in this instructable will help you to create the following circuit. I demonstrate on the learning board, but you can do it all on your own with a breadboard!
