Run/Stop Relay Circuit

Published:2013/3/27 4:22:00 Author:Ecco | Keyword: Run/Stop Relay

Safety is a major concern in a good many motor-driven applications. This is true in industrial applications where motion starts when power is applied and especially true when power is restored after an outage. In such cases, unwanted or unexpected motion is a risk to life or limb. The most simple solution to this problem is the simple, time-proven Run /Stop Relay Circuit. With this control circuit, motion cannot commence (or restart) without the operator’s specific pushbutton command. While simple, there are numerous variations and enhancements as you will see, and the benefits are clearly obvious.   (View)

Momentary Switch with 555

Published:2013/3/27 4:20:00 Author:Ecco | Keyword: Momentary Switch , 555

Based on NE555 this circuit turns on and off the IC output by a momentary switch. In other words it works as a mechanical latching relay, but the circuit backs to the start condition when you switch off the power supply. This feature is often required in automotive devices. No relay contacts are used, infact I connected the output to a led.   (View)

Arduino Panic Alarm

Published:2013/3/27 4:16:00 Author:Ecco | Keyword: Arduino Panic Alarm

Panic Alarm circuit consists of two equally important parts. The first part is the ready-made Arduino Microcontroller board, and the second part is an interface circuit which can be wired on a piece of prototyping board. You can use any standard 9V battery to power the whole circuit, and the Push-ON (push ‘n’ hold) switch (S1) to activate the alarm function. An additional Electro-Magnetic Relay (EMR) is also attached to the interface circuit.   (View)
