There are so many different circuits made with 16f84. A circuit with a display indicator that can measure inclination angle, the information received from the ADXL05 sensor is displayed on the 7 segment display with the microcontroller and 74HC164. The software has .asm and protel pcb schematic files prepared in assembly language.
An Inclinometer measures the angle of inclination that its sensor is leaning against. This project accomplishes this task using an Analog Devices ADXL05 Accelerometer. a PIC 16F84 as sensor and ‘brain’.
The analog signal is sampled from an Analog Devices AD7896 12-bit, serial analog-to-digital converter. The PIC receives digital data from this device and performs some conversions on the computer.
To be able to display the data, the result on 7-segment displays. A 74HC164 serial-to-parallel decoder is used because there are not enough spare pins on the PIC to drive 8 display segments
The circuit uses an ADXL05 Accelerometer to sense the tilt angle. this particular arrangement can read from 0.0 to 89.9 degrees. VR1 provides a small Gain setting and VR2 provides an Offset setting that can be used to ‘reset’ the reading.
BT runs from a 5 volt source so the PIC is happy to work alongside it. U2 is optional, but can be used as a buffer so that the output signal from the accelerometer is not loaded down. PCB is in Protel Autotrax format.
