Animator is actually a 5×16 LED matrix device used to display simple animations :). Initially, the device was used for something completely different and was controlled directly from the parallel port using a program written in Pascal. The idea turned out to be a bit wrong, as the program does not provide an even refresh…
The operation of the thermometer circuit: If I explain the digital thermometer circuit made using the DS1621 temperature sensor. The operation of the circuit is as follows; The numerical value taken from the heat sensor is sent to the microcontroller with the help of serial communication protocol I2C and the microcontroller prints this value to…
I had searched a lot once for this type of circuit, although my searches were a circuit made with Microchip PIC Series. 6 relay control can be done via usb port. There are computer program pcb code usb driver and schematic files. The supply of the circuit is SPI and RS232 connections on the 9-12…
I quickly was able to appeal to the network card via a 8-bit data bus. The connectivity of the network card and thus the RTL8019AS chip via two 8-bit ports of the processor and an ISA slots. On external components such as memory was deliberately omitted from the beginning to keep the replica easy and…
In this circuit, temperature information is obtained by using PIC16F84A microprocessor and DS18B20 temperature sensor. The temperature information obtained is displayed on the 16X2 LCD screen, giving an audible warning when the temperature value specified by the user is exceeded. It enables the fan to operate until the ambient temperature drops to the desired level.…
In this circuit, the PIC16F84A microcontroller and 16X2 digit counter 12 is made using LCD screen. SWITCH button LCD each signal sent from the values of a which provides enhanced. If the RESET button on the LCD allows the values reset. LCD Display Counter Schematic LCD Display Counter Circuit PCB top Counter Circuit picbasic pro…
In this circuit, 0-9999 counter circuit is formed by using 16F84A microprocessor and 7-segment displays. The plus (+) button increases the counter value and the minus (-) button causes it to decrease. The RESET button resets the value in the counter. Materials used in 0-9999 counter circuit with PIC16F84A; 1 PIC16F84A microprocessor 4 x 7…
Web site counts the number of inputs to the circuit .. Circuit attiny25 an interesting and MAX7219 section based on the indicators used for the 7-segment display 8 hunting and Delphi source code are six examples of how electronics applications with Delphi can USB Physical Hit Counter based on AVR ATtiny25 This is an USB…
Methods Used in Circuit Design After deciding what to do in circuit design, it is necessary to choose or seek the methods that will save the most time and cost the least. Since our age is home to a time when science and technology may be running horses, there are plenty of alternatives in this…
Speed Meter Circuit consists of four parts. These Supply solid floor Sensor sensor, microcontroller and microcontroller solid hexadecimal numbers we obtained from the 7-segment display technology with time code converter solid. Program Keil µVision3 AT89C51 microcontroller. Supply DC 12V working with solids. However, by 7805 we have achieved solid display technology and microcontroller is supplied…
