Small electric organ circuits using NE556
Single IC Organ By IC NE556 When you will think to build Single IC Organ Circuit the some one. I begs for to advise this circuit , because use IC NE556 or LM556. Which within its structure is like have the integrated circuit IC 555 arrive at 2 together follow my circuit. Control by Keyboard contacts and SW1 Tremolo ON/OFF as a result can choose music pitch that can want.The detail about mini Organ Circuit the this. Can see in circuit picture sir.

Simple train whistle circuit using NE556
This is a simple train whistle circuit. We have many ways to generate a two-tone sound circuit. I love to collect a basic or small circuit. This circuit may be useful for you. When we press SW1, the speaker will emit the sound like a train whistle. It is suitable for sound alarms and other. The main component of this circuit is NE556, a great integrated circuit. This advantage of this circuit is small and cheap. Because it uses a single IC. Working out sound speakers directly. How this circuit works Simple train whistle circuit diagram When we take the …
Home burglar alarm with timer delay using one IC 556
This circuit uses IC 556 which have timer 2 the group in one. First group is moto stable and second group does in front is in a state of a signal goes out work to is unfinished although signal. From detect disappear already. But output a pin 9 still have voltage the tall when encourage from detect , which might be switch the door is model usual close the circuit, or be strip sticks at sheet window glass by detect every jigsaw serial puzzle all. When detect any one open the circuit. The circuit will encourage signal to warn immediately …
Car Burglar Alarm Timer Delay Using NE556
Car Burglar Alarm timer alarm system circuit , model to economize. This circuit convenients for to set up in an automobile. usually switch at set up keep with automobile door will the circuit closes. But in case of car owner opens in and out while note as a result have no result anything , because of the transistor model PNP to still don’t work. Because of 9 pin have high voltage. But when switch the door any one open the circuit exceed time delay keep 5 pin of IC NE556 have low voltage to fully drive transistor circuit give relay …
