★★★★ circuit diagram for stepper motor driver using uc3717a

♔♔♔ Stepper Motor Drive Circuit Block Diagram The UC3717 has been designed to control and drive the current in one winding of a bipolar stepper motor. The circuit consists of an LSTTL-compatible logic input, a current sensor, a monostable and an output stage with built-in protection diodes. The UC3717A is an improved version of the UC3717. It has been modified to supply higher winding current, more reliable thermal protection, and improved efficiency by providing integrated bootstrap circuitry to lower recirculation saturation voltages. The circuit is equipped with a thermal shutdown function, which will limit the junction temperature by reducing the output current. It should be noted however, that a short circuit of the output is not permitted.

★★★★ circuit diagram for celsius to digital thermometer using ad590 temperature sensor

♔♔♔ Circuit Diagram for Celsius-to-Digital Thermometer The following circuit diagram is designed by Elana Lian and Chau Tran from Analog Device. The circuit includes T1, a low-cost AD590 temperature sensor; IC1, an AD8541 rail-to-rail amplifier; four resistors; a trimming potentiometer; and an ADC. The AD590 is a 2-terminal integrated circuit temperature transducer that produces an output current proportional to absolute temperature. The AD590 provides an output current proportional to absolute temperature (1 ??A/K). In this application, the circuit offsets and scales the output to provide a full-scale range of 0 to 5V with a scale factor of 50 mV/??C over the chosen temperature range of 0??C?

★★★★ home wiring fuses and circuit breakers diagram

♔♔♔ home wiring fuse and circuit breakers In terms of home wiring system, fuses and circuit breakers are safety devices located on your electrical panel to prevent over loading and fires. They stop the electrical current if it exceeds the safe level for some portion of the home electrical system. Overloading means that the appliances and lighting in the home regularly demand more electrical current then the home electrical system can safely deliver. If the demand for electrical current exceeds the safe level a fuse opens once and must be replaced to reconnect the circuit.

Cheap Car Alarms, Practicality at Its Finest

Car alarms are essential these days die to the growing number of car thefts. If you are looking for practical means to afford one, there are inexpensive car alarms sold in the market already. Make sure that even if it’s the cheapest car alarm, it is still of good quality.Body: Car alarms are electronic devices that are installed in a car or any vehicle in order to discourage thieves from stealing a car or a vehicle and its contents. Car alarms emit a high-volume sound when someone triggers the alarm. The sound of car alarms are usually like a klaxon, a siren, verbal warning, the own horn of the vehicle or a combination everything mentioned.
Listed below are some tips on how to buy an affordable car alarm with good quality. The tips will help you spot a good car alarm from the bad one. This will also help you find the best way to find an installer for your car alarm so as to avoid any problems from occurring.
• Most people search on the World Wide Web in order to look for a cheap car alarm. The internet is full of websites that sell car alarm accessories and car alarms. The internet is also the best place to find cheap car alarms. The newest model of car alarms are those that page the owner via its remote that can work even at a maximum of 3000 ft whenever there is an intrusion. There is also a model that is called a “GSM based car alarm”. This so-called GSM based car alarm will call the owner on its cellular phone if there is a possible intrusion to the car. This can even allow the owner to listen to the activity inside the car. With this new innovation, the owner can now shut down the engine and talk to the robber with just a push of a button from the owner’s cellular phone. Advancements in car alarms include the GPS feature where in the owner can track the car’s or vehicle’s whereabouts via cellular phone.
• Some people buy either directly from a dealer, purchase from a shop or via internet transactions. There are many kinds of alarms for your car and different brand names as well. In order to differentiate which car alarm is of good quality, check its wiring harness. The thicker the wire, the better. This is due to the fact that it can withstand the electrical current. Low quality car alarms use very thin wiring.
• Look at the diagram of the wiring. Most good quality car alarms use the same color coding. This is while car alarms of low quality use a different one. The idea of a universal color system makes an experienced installer install a car alarm in no time. If the color coding is different, the installer can have a hard and long time installing the car alarm. This can also waste precious time and money if ever the installer charges his services by the hour.
Below is a list of how the wiring must be coded.
The “RED” wire is equal to 12+ Positive
The “BLACK” wire is equal to Negative Ground
The “WHITE” wire is equal to Parking Lights
The “BROWN” wire is equal to Siren
The “BLUE” wire is equal to Shock Sensor or Sensor Input
The “ORANGE” wire is equal to Negative when Armed
The “VIOLET” wire is equal to Door Lock
The “PURPLE” wire is equal to Door Lock
The codes listed above are basically the wire connections on the car alarm’s main harness. Alarm systems have lots of wires but the ones listed above are most important ones that any customer must look for.
• When choosing a car alarm, buy the one that comes with or without the integrated immobilizer. In the United Kingdom, choose the Non Tatcham or Tatcham approved car alarms. Most cheap car alarms are easy to install or can be a DIY (Do It Yourself) type. The Tatcham approved alarms should be installed by a qualified and experienced installer.
• The cheapest car alarm that is of good quality is the Non Tatcham alarms that have no immobilizer. This car alarm is available via a do it yourself installation. The only thing that the owner will do is to connect the courtesy light, sensors, central locking and power supply. If the owner arms the car alarm, the “central locking technique” will allow the cars to lock as well as close the windows because of its automatic window closure technique.
• Most cheap car alarms cost only 100 dollars but their quality is superb! Listed here are two cheap car alarms:
1. Wrap Steering Wheel Lock: This car alarm is cheap and has a four-star rating. This kind of alarm covers the vehicle’s steering wheel so that the airbags will not be stolen. This steering wheel has a dual function since it works as a car alarm and a steering wheel lock. These are practically provided in one simple package. This is the reason why this car alarm has a high rating. The buyers of this product loved its results.
2. The so-called Crime Stopper: The “Crime Stopper” or the “CS2011DPII Deluxe Vehicle Security Alarm/Remote Start Combo” contains a siren that has up to 6 different tones. The tones of this car alarm is being projected at a high decibel level meaning no one will be able to ignore this alarm once it has been triggered. The “Crime Stopper has about 4 outputs where in 2 are programmable and the other 2 outputs are fixed. This car alarm also has about 30 diverse programmable options.

★★★★ circuit diagram for motor control sensor by jim lepkowski

♔♔♔ AC motor current measurement This Motor Control Sensor Feedback Circuit Diagram article is written by Jim Lepkowski from Microchip Technology Inc. Sensors in motor control are used to sense the current, position, speed and direction of the rotating motor. In most motor control systems, several sensors are used to provide feedback information on the motor. These sensors are used in the control loop and to improve the reliability by detecting fault conditions that may damage the motor.

★★★★ 2 watt amplifier circuit diagram

♔♔♔ 2 watt amlifier circuit diagram The following circuit diagram is made for a 2 watt audio amplifier. This amplifier has a wide frequency response, low harmonic distortion about 1.5%, and is capable of driving an 8 ohm speaker to output levels of around 5 watts with slightly higher distortion. The amplifier operates in Class AB mode; the single 470R preset resistor, PR1 controls the quiescent current flowing through the BD139/140 complimentary output transistors. This amplifier has a S/n ratio of 115dB at 1kHz. Overall gain is provided by the ratio of the 22k and 1k resistor.
