The industrial name of this instrument is "Tachometer". It is an important measuring device in the field of electrical engineering & widely used in industries and laboratorial work.Mohaimenul Islam
I've also included a pipe diameter calculation mode, an inside corners mode (not in video above, see modes in Step 14), and a tachometer/speed mode (for low RPMs). The modes can be re-ordered or removed easily in the code. The brains of the DMW is an common Arduino Pro-Mini, whi...
6). Digital Thermometer using Arduino This project is mainly used for designing a digital thermometer with the help of an Arduino. This kind of thermometer is used to check the room temperature. This project can be built with LCD display, LM35 temperature sensor & Arduino Uno board. The contr...

[Glen Akins] came across a tachometer for a jet airplane, which he promptly turned intoa unique CPU utilization gaugefor his computer. Much of the write-up is concerned with probing the instrument’s innards to learn its secrets, although it was clear from the outset that his tachometer, ...
To drive 40 LEDs from one Arduino requires either a bit of jiggery pokery (Google “charlieplexing” if you’re interested) or, to cut the Gordian knot, simply buying a bit of extra hardware to do it. I opted for the latter given my lack of time. I went for the Maxim 7221 (from...
In this post I have explained how to test mosfets using multimeter through a set of steps, which will show help you to accurately learn the good or faulty
In a YouTube video, he shows how the whole setup works. It began with an Arduino circuit board with a Bluetooth link to a smartphone — in this case, an iPhone 6S Plus. An optical tachometer was fitted to the board, which cleverly monitors the amount of time it takes for a wheel to...
The tachometers have changed a lot due to rapid development of modern electronics. This article is for a contactless digital tachometer using Arduino. Here the speed of the motor is also controlled. The RPM, the duty cycle and other information are displayed on a LCD screen.Md. Masud Rana...
Arduino NanoE18-D80NK SensorLCDRPMTachometerA good and feasible centrifuge is needed in the world of health, therefore a digital tachometer is needed to calibrate a centrifuge. Digital tachometer is a measuring instrument used to measure the rotation speed of a motor. This tachometer will be ...
