The hot melt glue that covers the circuit serves multiple purposes: It helps to keep the temperature even among the three transistors (to minimize thermal drift), it protects the components from physical damage, and it holds the battery holder on the board. As I used this probe last nigh to determine if a 384 MHz […]

DTMF is an abbreviation of Dual ToneMultiple Frequency. When you press a button in the telephone set keypad, aconnection is made that generates a resultant signal of two tones at the same time. These two tones are takenfrom a row frequency and a column frequency. Theresultant frequency signal is called “Dual ToneMultiple Frequency“. These tones are identical and […]

The ATmega8 microcontroller-based Low-Cost Telemetry Device (LTD) is an efficient telemetry keyer. The LTD measures the voltage levels of up to four analog channels via its on-chip 10-bit ADC, converts the measurements to numbers, and then sends the data in Morse code to an external transmitter and to an attached RS-232 terminal. It can be […]

A well known L/C measurement circuit is pressed into service to make a bare bones measurement circuit. Download the AVRStudio assembly source: lgm031227I.asm Download the AVRStudio hex file: lgm031227.hex Left-to-right: The 5 volt regulator, the LM393 oscillator (a 0.047 uf capacitor is mounted on the LC circuit connector), the AT90S2313, and the serial connector to […]

Useful as a transmitter tune-up meter or an RF sniffer, this is an RF field strength indicator that is loosely based on the Broad Band RF Field Strength Probe, described elsewhere. It detects RF via a square law detector, basically its a crystal set with gain. For more detail: AVR LED RF Field Strength using […]

Once upon a time, though a circuit of this type of calling Searches Banim made with Microchip PIC Series devreydi 6 pcs rörele control pcb computer program code can be done via usb port usb drive and 9-12 volts AC regulated power supply section of the circuit’s schema files on the SPI and RS232 connections […]

DS1621 temperature sensor circuit digital thermometer to tell if using. Operation of the circuit is simple, as are as follows: temperature sensor from the numeric value being sent to the microcontroller and the microcontroller using the I2C serial communication protocol, this value will more basıyor.Biraz If the LCD tomicrocontroller interprets the sensor in the 16-bit LCD to the data transfers.

Microcontroller Microcontroller ‘s (MCU) is a kind of CPU (CPU) can be seen as. MIB MCUs from slower and less capable of addressing memory, but they are designed for the implementation of real-time control problems both cheaper and easier to use. The major difference between CPU and MCU are required to use external hardware. MCU, almost every time, […]

Animator is a device, rather 5 × 16 matrix LED , which are used to display simple animation. Initially, the device serves to something completely different and it was controlled directly from the parallel port for the program is written in Pascal. The idea has proved to be a bit pointless because the program does not provide an even […]

This color of the surface color to red when you bring to the surface, a sensor to read the LDR, yellow, blue.Red, yellow and blue lights in different surface finishes as a different yansıtmalarını works by taking a foothold. Will be reflected from the surface to send 3 ledlights, this ledlerin to read the value of LDR, […]
