PIC16F88 LCD Tachometer Circuit

PIC16F88Rpm analog voltage output that is, PWM signal so that only the output filter will depend on VDD. While there, press the switch, use the calibration and output voltage range equivalent to the rotation. 0-6000, for example when a voltage range of 4.8V to press on with this switch. Analog output voltage is 2.4V when you rotate 6000×2.4/4.8 = 3000rpm. ROHM detection sensors are made of reflective sensors RPR-220 was used. 6mm from the tip of the infrared focal point was set at an angle of LED (940nm) is now one of the phototransistor. It looks like some of 630nm light source PIC16F88 HI-TECH PICC software production has been created. CCS-C with a little modification should be transplanted. I am, I have an older version, most (at all) is not being used.

Tachometer Circuit Specification

Range: 17.9 ~ 99999.9 rpm (or so to about errors 20000rpm)
Sensor input: Voltage values. The reflection of the actual measurement is adjusted for RB0 interrupt edge
Analog output rotation: 8 range, 0 – full-scale :0-VDD (10bitPWM)
Analog output range: 300,500,1000,3000,6000,10000,30000,60000 rpm
HOLD switch: While the press, sensor input, to hold the rotating numeral
TEST switch: While the press, full-scale output voltage analog output
A-RANGE switch: Change the value of full-scale analog output

    ISD2560 Voice Recording Playback Project PIC16F84 Controlled

    ISD2560 to directly control the PIC16F84A, audio recordings and multiple block will be able to play. LSI can be driven directly speakers also, in view of the lack of volume, only added to the amplifier IC. This volume 10 minutes to drive the speakers. One LSI chip for voice recording playback “ISD2560” using a simple audio recording and playback unit prototype it

    ISD2560 is playing this voice recording, in the same basic configuration, the sampling frequency, Divided into the following series. The use of the series in the most wide-frequency band; Instead of recording time limited to 60 seconds.

    PIC16F88 LCD Drehzahlmesser Schaltung

    PIC16F88 analoge Ausgangsspannung, die, PWM-signal, so dass nur die Ausgabe-filter hängt auf VDD. Während Sie dort sind, drücken Sie die Taste, verwenden Sie die Kalibrier-und Ausgangsspannungsbereich entspricht der rotation. 0-6000, zum Beispiel bei einem Spannungsbereich von 4,8 V zu drücken, mit diesem Schalter. Die analoge Ausgangsspannung ist mit 2,4 V beim drehen 6000×2.4/4.8 = 3000rpm. ROHM-detection-sensoren werden von reflektierenden sensoren RPR-220 verwendet wurde. 6mm von der Spitze der Infrarot-Schwerpunkt war in einem Winkel der LED (940nm) ist heute einer der Fototransistor. Es sieht aus wie einige 630nm Lichtquelle PIC16F88 HI-TECH PICC-software-Produktion erstellt wurde. CCS-C mit einer kleinen Modifikation sollte transplantiert werden. Ich bin, ich habe eine ältere version, die meisten (alle) nicht verwendet wird.
