BCD Counter Circuit
https://www.electronics-lab.com/article/bcd-counter-circuit/
BCD Counter Circuit A special digital counter called a BCD counter may count up to ten when a clock signal is supplied. As previously demonstrated, toggle T-type flip flops may function as separate divide-by-two counters. By joining many toggle flip-flops in a series chain, we may create a digital BCD counter that counts or shows […]
Bidirectional Counters
https://www.electronics-lab.com/article/bidirectional-counters/
Introduction A bidirectional counter is a binary counter that operates synchronously in both up and down directions. It is capable of counting both toward & away from a predefined number and back to zero. Any given count sequence can be counted by such bidirectional counter in either the up or down direction. It is occasionally […]
Asynchronous Counter
https://www.electronics-lab.com/article/asynchronous-counter-2/
Asynchronous Counter “Asynchronous counters” are those counters in which where various flip-flops are driven by various clock signals at their clock inputs. Only the first flip-flop in an asynchronous counter is externally synchronized using a clock pulse; all subsequent flip-flops in the counter use the output of the preceding flip-flop as their clock input. Asynchronous […]
BeanCounter is an “Affordable” SMT Parts Counter that operates on a CR2032 coin cell
https://www.electronics-lab.com/beancounter-is-an-affordable-smt-parts-counter-that-operates-on-a-cr2032-coin-cell/
As a part of the Microchip Get Launched design competition, Virginia-based Great Big Factory, an electronic device manufacturer, has designed SMT parts counter that runs on a CR2032 coin cell– BeanCounter. Yet to be launched for crowdfunding on CrowdSupply, the manufacturer has provided enough details to decide if this is a product you would want […]
100MHz Frequency Meter using ATtiny414
https://www.electronics-lab.com/100mhz-frequency-meter-using-attiny414/
David Johnson-Davies published a new project on his blog. This project is a simple frequency meter capable of measuring frequencies up to 100MHz with an accuracy of 0.002%. Based on an ATtiny414, it demonstrates the use of Timer/Counter TCD0 and the Event System: I recently wanted to design a frequency meter that would measure up […]
Arduino Compatible 2-digit 7-segment Display Board for Timer/Counter
https://www.electronics-lab.com/arduino-compatible-2-digit-7-segment-display-board-for-timer-counter/
The project presented here is an open source 2-digit 7 segment Arduino compatible display board. It can used in many applications that require 2-digit display and switches inputs. Possible application of this board is a 2-digit counter, 2-digit countdown timer, token display, score board etc. 2 x 7 segment 0.56-inch Common cathode displays are used […]

This counter is made only from an ATtiny13 and LED diodes. Did you ever need a cheap and simple (with one digit only) pulse counter? This is the maximum optimization and simplification. Thanks to Charlie Allen. The Cheapest and Simplest Pulse Counter – [Link]
YouTube channel IoT view counter
https://www.electronics-lab.com/youtube-channel-iot-view-counter/
Kenneth Finnegan built this YouTube channel IoT view counter. He writes: I’ve wanted an Internet connected read-out for some time now, inspired by the awesome shadow box IoT projects Becky Stern has been doing (weather, YouTube subscribers). I’m certainly not to the same level of packaging as her yet, but I’ve got a functional display working […]
MyPart, An Open Source Portable Air Particle Counter
https://www.electronics-lab.com/mypart-open-source-air-particle-counter/
One of the most harmful airborne pollutants with respect to human health is particulate matter. Air particle counters are used to determine the air quality by counting and sizing the number of particles in the air. This information is useful in determining the amount of particles inside a building or in the ambient air. It […]
