The miniscule event counter based on a microcontroller is built using the affordable Digispark Attiny development board. A benefit of this design is that it can be connected to its trigger input regardless of whether it is an active or passive switch. Every time the switch is turned on, the microcontroller will count the event […]
The following steps will enable you to build your own tweiger-counter! It searches in current twitter messages sent around the globe for the words like nuclear, calculates a sliding window average and pushes it to the arduino that will click for every incoming tweet like an original Geiger counter and will steer a servo as
Hey! Today i’m gonna share with you one of my lastest quarantine projects, i’m talking about this awesome NodeMCU based Youtube Subscriber and View counter! It’s a pretty simple project that can be done in an hour or less so let’s get started! Supplies NodeMCU LCD 16×2 with I2C Some wires Breadboard 3D Printer (This is optional) Step
Have you ever needed to count something? Sure, we all need to count change, count blessings, and occasionally count cards, but that’s not really the kind of counting I’m talking about. In this Instructable, I will elucidate how Counting ICs operate, and show how to connect one to a microcontroller so you can see exactly
This project originated from a request of a friend. He asked me to build a so-called smile counter for their college dorm – a segmented display which can show a number. This number must increment every time someone pushed a button and should be memorized even if power goes out. The counter was counting smiles:
Let’s start of with a question: What is a people counter? …. Well, it is a device, that counts the amount of people passing by. They are usually placed in doorways and can be used to see how many people are in a room or a restaurant or a store at any given time. The
This is a YouTube Subscriber counter built with an ESP8266. It uses the YouTube apiv3 to poll for changes. It’s made specifically for one of my favourite youtubers Henk Rijckaert. It was featured in his livestream where the goal was to get to 9000 subscribers. Step 1: Parts Needed – Electronics and Case The project is
Where the honeybee’s division of labor has stayed on a steady progression for 25 million years… our human superorganism has grown more complex and in all directions… hence the bee counter… By: thomashudson.org Live data from – June 25, 2012 I’ve moved away from live data… my version 2 has an SD card and I’m
Many times, we often use LCD as display equipment, from tiny temperature monitors to large industrial equipment. The funny thing in this project is that it combines two Red LED Matrices as display. You don’t need other devices except Arduino to drive it. This project is build for to counting the shipped with wifi support.
My previous Instructable covered the basics of detecting dart speed using an infrared emitter and detector. This project takes it a step further, using a printed circuit board, display, and batteries to make a portable ammo counter and chronograph. Additionally, we add some LEDs to simulate muzzle flash. Because, pew pew pew . . .
