Microcontroller Programming
This page is a work in progress. The board and source files will soon be available for building and programming to play custom songs. After assembling the board, communication with the programmer was verified, and both the LED and switch...
measurement conductance cell constant
A small transmitter board interfaces with a microcontroller and conductivity probe to measure liquid conductance and conductivity. Precise equations and measurements are provided for this microcontroller-controlled conductivity meter.
The described circuit consists of a compact transmitter board that serves as an...
1300 Mhz Frequency meter with prescaler
Having found a u664b prescaler chip (Telefunken) from an old TV tuner, I decided to build a valid frequency counter using PIC16F84. The prescaler I use is able to divide by 64 every frequency from 30 to 1300 MHz. The...
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...
Cheap frequency meter by CA3130
This inexpensive frequency meter circuit is suitable for general use in small laboratories. It is cost-effective, easy to construct, and sufficiently reliable for most electronics enthusiasts. The frequency can be directly read from the meter, with a measurement range from...
Frequency meter with 10Hz to 2MHz
The 7208 seven-metric system counter is utilized as a frequency meter. It features a latch and multiplexing function and incorporates a direct drive circuit along with a display driver circuit. The 7207 IC divides the output frequency of a 6.5536...
Password Based Door Locking
Security is a prime concern in our day-to-day life. Everyone wants to be as much secure as possible. An access control for doors forms a vital link in a security chain. The microcontroller based Door locker is an access control...
Debounced Counter Made From Off-The-Shelf Chips
The true utility of the SR latch is evident during transitions of the input switch. Assume that the input switch is of the break-before-make type and starts in the up position. When the switch is up, the input values are...
digital counter circuit
The Digital Counter Circuit is an electronic project that converts digital numbers (0-9) to binary (0-1). For those interested in understanding binary code, a PowerPoint presentation on the topic is available. Below are the parts list, schematic, and additional information...
