Craft Your Own Wireless Frequency Meter with Arduino: A DIY Guide

This project details the development of a wireless Arduino frequency meter capable of determining the frequency of AC sinusoidal waveforms between 50Hz and 3kHz. Figures 1 and 2 depict the prototype hardware constructed for the transmitting and receiving functions. Figure 1 shows the transmitting circuit board which incorporates the frequency sensing components. Figure 2 presents

Other Projects / By Ibrar Ayyub

There have recently been a series of web query projects that use the miraculously tiny and affordable ESP8266 micro controllers. Most have involved the output going to a tiny screen with small graphics. The local YMCA in Anchorage just completed a beautiful remodel but lacked funds for decorative elements. I wanted to build them something

Blood Oxygen Heart Rate Meter

Metering – Instrument Projects / By Ibrar Ayyub

This instructables show how to use MAX30102, XIAO and a tiny display to build a blood oxygen and heart rate meter. Step 1: Sensor & Algorithm This project use Maxim Integrated MAX30102 Biosensor to detect pulse oximeter and heart rate. However, the official sample is not so accurate, so will use the MolecularD algorithm instead. Ref.: https://www.instructables.com/Pulse-Oximeter-With-…

Arduino Audio Sound Level Meter

Sound – Audio Projects / By Ibrar Ayyub

This is add-on of the audio amplifier project result which is introduced in other instructable. (https://www.instructables.com/PC-Speaker-Amplifier/) Usually many types of sound level meters are directly connected with input (or rarely output) signal lines of amplifier. But personally I’m thinking any electrical connections with amplifier circuit may surely degrade music playback quality by inserting some noises

Versatile Volt, Ampere, and Power Meter

Metering – Instrument Project Ideas / By Ibrar Ayyub

Multimeters are suitable for many purposes. But usually, they only measure one value at a time. If we deal with power measurements, we need two multimeters, one for voltage and the second for Ampere. And if we want to measure efficiency, we need four multimeters. Here we will build small and inexpensive meters to do

Arduino Energy Meter – V2.0

Metering – Instrument Projects / By Ibrar Ayyub

Hello friend, welcome back after a long break. Earlier I have posted an Instructables on Arduino Energy Meter which was mainly designed to monitor the power from the solar panel (DC Power) in my village. It became very popular on the internet, lots of people all over the world have built their own. So many students have
