doorbel
This smart doorbell system is designed for use in industrial environments. It is microcontroller-based and controls a horn and a flashlight.
The smart doorbell system utilizes a microcontroller to manage its operations, making it suitable for industrial applications where reliability and...
pc based digital ic tester
Check the following ICs: 7400, 7402, 7404, 7408, 7432, 7486. A Visual Basic program is utilized to display the results on the PC. The microcontroller AT89S52 receives the IC number from the PC, verifies the logic gates with the truth...
Ultrasonic Reflectance Detector
This circuit detects motion within approximately 5 inches of a piezo-ceramic element ultrasonic transducer. The detection distance is much smaller than obtainable with other ultrasonic techniques; however, it only requires a single transducer, as opposed to the two-transducer arrangement typically...
The Application of TDC-GP21 in Ultrasonic Heat Meter
Enhancements include an analog front end, pin-to-pin compatibility for existing designs, an analog stabilized comparator, and simplified external circuit design. There is improved time and temperature measurement with reduced current consumption. The TDC-GP21 is ideally suited for designing compact and...
Ultrasonic Switch
Ultrasonic Switch. A circuit of a new type of remote control switch is described here. This circuit operates with inaudible sound waves.
The ultrasonic switch operates by utilizing ultrasonic frequencies, which are sound waves above the range of human hearing (typically...
Digital Step-Km Counters
This circuit measures the distance covered during a walk. The hardware is housed in a small box that can be slipped into a pocket, and the display is designed as follows: the leftmost display D2 (the most significant digit) shows...
Electronic TIC TAC TOE
This project is not to introduce Tic Tac Toe. Everyone knows this game. It is to introduce two features: bi-coloured LEDs, microcontrollers, and the skill of writing an ALGORITHM. You can use the project to learn the skills of creating...
Ultrasonic Parking controller
A series of five short pulses blasted by the microcontroller only has 5V amplitude, which will be attenuated down to less than 20 mV when received by the receiver circuit. Hence, LM311 voltage comparator was used for signal amplification before...
Password(code) Based Digital Locking System Using Microcontroller 89C52/89S52
Upon entering the password, the application, in this case "LED," will illuminate. In this digital locking system project, the interfacing of a keypad and a 16x2 LCD with a microcontroller will be explored, along with the accompanying code. This project...
