The project shows you how to build a combination lock for your home door using PIC16F84 MCU and electro-magnetic lock. A 4×4 keypad, located outside the door, is used to enter key combination. The master combination will open the door, as well as allow programming of up to four transient combinations, the illumination duration, [...]
This imaging sonar project uses two PIC microcontrollers, PIC16F84 for the servo control and PIC16C71 for the sonar portion. It’s equipped with two 40 KHz ultrasonic transducers, one for transmit, one for receive. These transducers are steered by an R/C servo over 180 degrees of azimuth.
This project shows you how to implementing your own Web/WAP enabled home automation system. It will allows you to control the on/off state of up to eight 3A appliances via either a web browser or a mobile phone.
This frequency counter can measure frequency with range 100Hz-2.5GHz. The project features including LCD 16 chara.x 2 lines and TCXO 12.8MHz(1ppm ). The project main part is PIC16F84. The Voltage(0-510mV) of the input signal is also indicated on the LCD , therefore tuning of the coil can be conducted while checking the frequency.
