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

Smart Remote Atmega88 Circuit Copy the two buttons
The only control that are not in the market for copy and discontinued controls over tv, satellite receiver, etc. “smart control” to control such devices sold will be copied to the control as a simple smart control right lar and copying smart control signal mutual buttons to press.
Atmega88p made with one of the most fundamental examples of intelligent control circuitry for the control to follow the situation more clearly understood that the test video. the circuit diagram of the application and have the C codes CodeVision
