Where to use NE IC. The NE IC is the dual version of NE IC, meaning the NE has two timers inside it. As we know ICs have. Also know about Timer, timer -pin description, features and applications. Timer IC is an integrated circuit used in a variety of applications like. The dual version is called It features two complete s in a 14 pin package. Only the two power supply pins are shared between the two.

A dual tone train horn simulator circuit can be made using two NE timers connected in cascade. Switch S1 can be used to start the horn.

NEN Dual Timer IC Pinout, Features, Working & Datasheet

The circuit is simple and low cost but works greatly. This circuit can be modified to make the train horn turn ON when the train is about to reach different stations, level crossings, single lane tracks and so on. In the circuit above, a Switch S1 is used to manually and momentarily turn on the two-tone horn. This horn can be turned ON automatically at certain points on the track by mounting a reed switches under the track at the lc where the horn is to be heard.


The reed switch will turn ON if the magnet is placed on nne556 bottom of the train and it passes through the track. All you have to do is place the reed switch in such a way that it faces upwards.

555 timer IC

Water Activated Musical Ci. Ideally we would like to output 12Vdc to activate a Pizeo Siren. Plus have the first tone triggered every 4 seconds preferably adjustable from 2 — 10 SecondsAfter 4 Beeps on the first tone a second tone is sounded but of a different sound level. Ideally the first Tone is to hook the hooks onto the line and the second tone is for the Ne56 to be hooked on to the line.

Willing to elaborate more if i am not understandable. Thanks and hope we can work together on this.

I built this circuit but get more of a convenience store door alarm out. The nw556 difference is I used two timers and they are not the same.
