Automated Car Parking Sensor Circuit

Automated Car Parking Sensor Circuit, For people who are just learning to drive a car, parking is one of the hardest parts. Because when parking backwards, the driver must be careful and careful in estimating the position of the car to the parking space just by looking in the rearview mirror. Take it easy, because you can create an electronic circuit that can help you park your car backwards.

The working principle of this circuit is actually very simple. The sensor is only in charge of detecting the distance between the rear bumper and the wall or objects that block it. When the distance is too close, the sensor will issue a notice to the rear bumper of the car does not hit the wall and cause damage.

The series of parking sensor of this car consists of two parts, namely the transmitter and the receiver. Here is a complete car parking sensor circuit scheme that you can make reference to make your own simple car parking sensor.

Picture transmitter circuit scheme:

Picture receiver circuit scheme:

The output of this series is 3 pieces of LED. When the car and wall bumpers are 30 cm apart, then 1 LED will light up. When the car and wall bumpers are 25 cm apart, 2 LEDs will light up. And when the car and wall bumper is 20 cm away, 3 LEDs will light up, and the driver must stop the car.

That way the car and wall will not happen. Oh yes, both circuits use DC voltage of 12 volts. You can take it from a car battery or make your own power supply circuit. What is certain in the circuit using some of the ICs that are easy to find in the store electronics components around you.

Seven Segment Driver Series With IC 74HC595

The seven segment series is a series that serves to control the 7 segment display. Seven segment itself is basically a combination of several LEDs that form a digital number pattern. To turn seven segment in accordance with the desired number then it takes a series of seven segment drivers. The seven segment driver series is actually optional, can be used can not. If not using 7 segment driver circuit, 7 segment connection can be directly connected with microcontroller controller. A series of seven segment drivers is required if the display used is large enough, so the voltage required to power 7 segments is also large. For such cases a 7 segment driver is required as an intermediary between the microcontroller with 7 segments.

There are so many types of seven segment series that you can use. You can find references in google about this segment 7 segment driver. On this occasion I will discuss one of a series of seven segment using TTL IC type 74HC595. This IC is an IC shift register, its function is to change the input in the form of serial data into parallel data which will be connected to 7 segment display. But this series you can develop for drivers more than 4 digits once you understand the working principle.

IC 74HC595 has some input and output pins. The input consists of the following pins:

• SH_CP, is the clock input pin
• DS, is the input pin of serial data
• ST_CP, is the data latch pin
• MR, is the clear pin output. If this pin is low then the output will be all 0
• OE, Output Enable pin that serves to enable output

While the output of IC 74HC595 consists of pins Q0-Q7 and Q7 '. Pin Q0 - Q7 is a parallel data output that is inserted serially from the DS pin. While pin Q7 'is a serial output that can be connected with other IC 74HC595, as seen in the picture above 7 segment above.

Serial data inputted through the DS pin, every 1 bit of data must be accompanied by 1 cycle clock. The serial data entered as much as 32 bits, because the above circuit there are 4 pieces IC74HC595 where 1 piece of IC has 8 bits of output data. After 32 bits of data entered, to output the output in parallel concurrently pin ST_CP must be set high then low.

The seven segment series is quite simple and cheap to make. There is one more 7 segment driver circuit that uses IC MAX7219. The principle works more or less the same as IC74HC595.

Simple Power Bank Circuit

Power bank is one of the most important tools for now. This becomes a problem in itself when the smartphone features more sophisticated. Power bank is one solution offered to handle the problem. With the power bank we like to have more backup batteries and very helpful at all when traveling.

Maybe for you fans of the electronics world, see the power bank will certainly be curious. Actually like what is the inside of the power bank circuit? Or how the hell do I create a power bank circuit? Can we make our own power bank? Well, the answer I will explain in this post.

Power bank consists of several main parts, namely as follows:

1. Battery
2. Battery Charging Circuit
3. Charging Gadget Circuit

Battery, is a temporary power storage medium. Battery on the power bank must be a battery that can be charging or recharging. Not disposable batteries such as ABC batteries or Alkaline batteries. Although the battery can actually be used, but can not be re-charging. Batteries used in power banks are usually Ni-MH batteries.

Battery charging circuit, is a series of electronics that serves to manage the charing process on batteries. Ni-MH batteries have special provisions for the charging process. Should not be in-charging. Arusa and voltage during charging process must be in accordance with battery specification. If the charging process is not correct, then the battery will be more quickly damaged. Or usually called baterei has leaked. Well, this battery charging circuit function to keep the current and voltage used to mencharging in accordance with battery specifications. So the batteries become more durable.

Charging Gadget Circuit, is part of the power bank circuit that serves to manage the voltage and current that will be used to mencharging gadgets. To charge the smartphone battery, it should not directly use the output of the battery power bank. Due to battery voltage and power flow of the bank does not match the battery that will be in charging smartphone. Therefore it is necessary gadgets charging circuit to adjust the voltage and output power of the bank.

To make the power bank circuit itself basically only needed 3 main component that I have mentioned above. May need additional switches and led lights as a flame indicator of the power bank. For batteries, you can use batteries used laptop.

For battery charging circuit and gadgets charging circuit you can buy the module in electronic component store. To make this circuit a bit more complicated because the range is quite complex. Therefore I recommend to buy it, because the price is also not expensive. Once the above components are complete, you can start to assemble your own power bank.

Picture scheme of power bank circuit below:

You only need to connect the cables according to the above sequence. And if so, please test to do charging to your smartphone. Make sure your circuit is correct before trying it!

Simple Power Supply Circuit Suitable For Beginners

Simple Power Supply Circuit is a must-have on an electronic device. Power supply circuit has the main function to supply voltage for other circuit. In electronic appliances such as TV, Computer, DVD or others need power supply. Power supply is also very needed for you who hobby in the field of electronics. To conduct experiments to make electronic circuits, surely need a power supply as a voltage source. Actually a lot of power supply is also sold in the market in a ready-made form. But maybe the price is somewhat expensive for you. Well, therefore in this tutorial I will discuss the topic about making a simple power supply circuit that you can practice at home. Make sure you understand basic about electronics if you want to practice how to make this power supply circuit.

Parts In Power Supply Circuit:

1. Voltage Reduction (Step Down)
2. Rectifier Circuits
3. Filter Range
4. Voltage Stabilizer Circuit (Regulator)

Voltage circuit is a circuit that serves to reduce the AC voltage from 220 volts to a lower voltage. As you know, the power voltage in our house is 220 volts AC. To make the power supply circuit, 220 volt AC voltage must be lowered first so that the voltage becomes lower. The voltage drop can use step-down transformer.

Rectifier circuit or commonly called a rectifier circuit, is a circuit that serves to make the AC voltage (back and forth) into DC voltage (unidirectional). This circuit uses a combination of several diodes. There are 2 types of rectifier circuit that can be used to make power supply. Among others are as follows:

1. Half Wave Rectifier
2. Full Wave Rectifier With 2 Diodes
3. Fullwave Waveguide With Diode Bridge

Voltage stabilizer circuit or commonly referred to as a series of regulators, is a circuit that serves to stabilize the voltage at a certain value. This circuit usually uses a special IC regulator. There are 2 types of regulator ICs that are usually sold in the market that is Linear Regulator and Switching Regulator.

Linear regulators are widely used to make simple power supply circuits. Because this type of regulator pretty much sold in the market. This linear IC regulator is usually glowing 78XX or 79XX. Where XX is the regulator output voltage. Example if the desired power supply with output voltage of 5 volts then linear IC regulator used is 7805. If desired is a power supply with 12 volt output voltage, then used is IC regulator 7812.

Image Simple Power Supply Circuit:

The power supply circuit above uses a step down transformer type zero transformer. While the rectifier circuit uses a full wave rectifier type with H-bridge. Then as filter circuit used electrolytic capacitor with value 1000uF and 1uF. For the regulator is used IC type 7812, so the output of simple power supply circuit above is 12 volt with the ability to supply current of 1 ampere. The above circuit you can make at home with plain PCB or PCB holes, so it can be used as a power supply for your experiment!
