Projek ini adalah berkenaan dengan kombinasi daripada perkakasan and perisian untuk sistem urut elektronik. Satu peralatan berprogram yang berkos rendah, berkuasa rendah dan saiznya kecil telah dibangunkan dan diselidikkan untuk menghantarkan bentuk arus yang berlainan. Dengan menggunakan PIC16F877A sebagai pengawal, peralatan itu boleh membekalkan julat arus (1-300μA) dan berbagai-bagai bentuk isyarat (arus terus, arus terus berdenyut, arus terus dwikutub dan arus terus berdenyut dwikutub). Arus boleh dikekalkan dalam julat yang besar dengan bantuan impedan dan tidak bergantung dengan bekalan bateri. Urutan asas itu mengandungi empat pilihan dan tiga masa bagi pengguna untuk memilih. Satu 1MΩ perintang boleh laras telah dimasukkan ke dalam litar untuk mengawal kekuatan daripada peralatan urut itu. Satu punat henti digunakan untuk membatalkan program itu apabila pengguna hendak memasuki isyarat baru. _________________________________________________________________________________________ This project is concerned with the combination of hardware and software development of an electronic massaging system. A low-cost, low-power, miniature, and programmable device has been developed and evaluated which can be programmed to deliver various current profiles for massaging purposes. Using PIC16F877A as a controller, the device can provide a range of current (1-300μA) of various signal waveforms (dc, pulsed dc, bipolar dc and pulsed bipolar dc). The current can be maintained over a wide range of impedance and is independent of the battery voltage. The basic massager has four modes and three timers for user to select. A 1MΩ variable resistor is inserted in the designed circuit to control the intensity of the basic massager. A reset/stop button is used to cancel the program when the user wants to key in a new input.
