Circuit Schematic Main Voltage Wireless Tester using CD4033

Eltronicschool. - Do you want to build your self the tester instrument in this time like to measure main voltage? when you want to build it, in here i will show you one of the tester circuit schematic for measuring or testing main voltage wirelessly look like in Figure 1 below.

The main of the heart of the circuit component is CMOS IC CD4033. So, in here we will show you more about this circuit schematic of Main Voltage Wireless Tester using CD4033, and we will give you the component parts, and description of this circuit.

Circuit Schematic

Component Part
  1. Seven segment
  2. CD4033 IC
  3. Resistors
  4. Capacitors
  5. Battery
  6. Switch
Description

Circuit schematic like in Figure 1 above is named Main Voltage Wireless Tester using CD4033. The main component to build this circuit is CMOS IC CD4033 that we think it is easy found in the electronic component market in your country.

How it works

According Circuitstoday site that also published this circuit, describe that with this circuit you can test whether mains voltage is present or not without you having electric contact with mains line. As the main component, the CMOS IC CD4033 consists of a 5 stage decade Johnson counter and an output decoder for converting the Johnson code to a 7 segment decoded output for driving 7 segment LED display. A 10cm long insulated copper wire connected to the clock pin (pin1) of the IC serves as the sensor. The sensor wire has to be placed in the vicinity of the mains wire to be tested. When there is no voltage in the mains line, no voltage will be induced in the sensor wire and the display will show a random digit. When there is voltage in the mains line, a small voltage will be induced in the sensor wire due to electromagnetic induction and this voltage is sufficient enough to clock the CMOS IC CD4033. It will count from zero to nine repeatly in the display seven segment.

Description

Circuit schematic like in Figure 1 above is Non Contact AC Voltage Detector using NE555 IC. According Circuitdiagram site describe that this is a very easy useful project of a non contact AC voltage detector circuit. The circuit will blink an LED and make beep beep sound when it detects any AC field. The circuit can be used to check AC voltage in wires, switches, plugs, wall sockets, electronic devices etc. without making a direct contact.
It will also show the phase and neutral wire from the two AC wires by making beep and blink LED only on phase wire and being in off state on neutral wire.

The circuit is using a 555 timer IC, a 2N3819 FET (Field effect transistor) with some resistors and capacitors. The 2N3819 transistor is working as AC field detector and the beeper circuit is built around the 555 timer IC.

The circuit can be operated from 6 to 12 volt DC. If you are operating the circuit with lower voltage then change the LED current limiting resistor according to the operating voltage to brightly blink the LED. On six volt you can use a 270 ohms resistor, On 9 volts use 320 ohms and on 12 volt use 470 ohms.

Techno Teachers: Finnish School Tests Robot Educators by Reuters

Eltronicschool. - This is one of the information for you you who want to know the robot educator in this time with the article here titled with Techno Teachers: Finnish School Tests Robot Educators that published in Reuters online.

Elias, the new language teacher at a Finnish primary school, has endless patience for repetition, never makes a pupil feel embarrassed for asking a question, and can even do the "Gangnam Style" dance.

Elias is also a robot.

The language-teaching machine comprises a humanoid robot and mobile application, one of four robots in a pilot program at primary schools in the southern city of Tampere.

The robot is able to understand and speak 23 languages and is equipped with software that allows it to understand students' requirements and helps it to encourage learning. In this trial, however, it communicates in English, Finnish and German only.

The robot recognizes the pupil's skill levels and adjusts its questions accordingly. It also gives feedback to teachers about a student's possible problems.

Some of the human teachers who have worked with the technology see it as a new way to engage children in learning.

"I think in the new curriculum, the main idea is to get the kids involved and get them motivated and make them active. I see Elias as one of the tools to get different kinds of practice and different kinds of activities into the classroom," language teacher Riika Kolunsarka told Reuters.

"In that sense, I think robots and coding the robots and working with them is definitely something that is according to the new curriculum and something that we teachers need to be open-minded about."

Circuit Schematic Arduino-based Front Office Visitor Alarm

Eltronicschool. - This is one circuit schematic for you who want to implement your Arduino in this time. With this circuit schematic, now you can learn more to connect and program your project based on Arduino microcontroller.

In this time, eside we will show you circuit schematic, we also will give you the description of this circuit and the last we will give you the link to read more about this circuit schematic from original source.

Circuit Schematic

Component Part




Description

Circuit schematic like in Figure 1 above is Circuit Schematic Arduino-based Front Office Visitor Alarm. Electronicsforu site describe that Arduino Uno operates off a 9V DC power supply. It is based on ATmega328 microcontroller and has 14 digital input/output pins, six analogue input pins, a USB connection for programming the onboard microcontroller, a 9V-12V DC power jack, an ICSP header and reset button. It is operated with a 16MHz crystal oscillator and contains everything needed to support the microcontroller.

Reed switch S1 is connected to digital pin 2 of Arduino as the input. PZ1 and LED1 are connected to digital pins 7 and 8, respectively, as outputs. LED1 is connected through a 220-ohm resistor.

Initially, when the door is closed, the magnet on the door is close to the reed switch (normally-open type) on the door frame and hence the reed switch is closed. So pin 2 of Arduino is ‘high.’

When the door is opened, the reed switch opens and pin 2 of Arduino becomes ‘low’ through a 10-kilo-ohm pull-down resistor. This turns on piezo buzzer PZ1 and LED1. After a few seconds, PZ1 and LED1 automatically turn off.

The software (office_visitor.ino) for this project is written in Arduino programming language. Arduino Uno is programmed using Arduino IDE software. ATmega328 on Arduino Uno comes with a bootloader that allows you to upload new code to it without using any external hardware programmer.

In this time, eside we will show you circuit schematic, we also will give you the description of this circuit and the last we will give you the link to read more about this circuit schematic from original source.

Circuit Schematic

Component Part

  • Raspberry Pi 3 Model B
  • EM-18 RFID Reader Module
  • RS232 – to – USB Adapter (as my RFID Reader has only RS232 Output)
  • Few RFID Cards or RFID Tags
  • Power Supply for RFID Reader (my RFID Reader has a 5V Regulator)
  • 5V Supply for Raspberry Pi and RS232-USB Adapter
  • Connecting Wires
  • 680Ω Resistor (1/4 Watt)
  • 1.5KΩ Resistor (1/4 Watt)


Description

Circuit schematic like in Figure 1 above is Raspberry Pi RFID Reader Interface using the EM-18 RFID Reader. Electronicshub site describe that On Raspberry Pi, the GPIO14 and GPIO14 i.e. Physical Pins 8 and 10 are the UART TX and RX Pins respectively. As we have already enabled the Serial Port of the Raspberry Pi, you can connect these pins to the external peripherals.

It is now a good time to note that Raspberry Pi works on 3.3V Logic. Hence, the RX Pin of the Raspberry Pin must only be given with 3.3V Logic. In order to do that, we need to level convert the TX line of the RFID Reader to 3.3V using a simple Voltage Divider Network consisting to two resistors.

I have used 680Ω and 1.5KΩ resistors. The output of the voltage divider is connected to the UART RXD pin of the Raspberry Pi i.e. GPIO15. Make a common ground connection between the Raspberry Pi and the RFID Reader Module.
