This code performs FFT with good accuracy.

Make your own mini oscilloscope at home. It’s simple and easy to do!

The soldering iron controller based on arduino that implements PID method to keep the temperature of the iron.

A simple to build, but very sensitive electromagnetic field detector.

Inexpensive to build but a very useful tool for every electronics laboratory.

A small device that will help you sorting resistors without wasting time with their color code.

Purpose of this project is to write a code to control coin acceptor with Arduino so it can be used in other projects

Showcasing our spot welder, which is controlled by an Arduino Nano.

This project uses a micro SD card to store a text file and print it out to a 16x2 liquid crystal display.

Build a 6x6 grid with an MPR121, expanding possible inputs from a mere 12 to 36!

A programmable, portable, rechargeable power supply based on Arduino featuring an OLED display for viewing V.I.P. of projects/prototypes.

A bit more accurate than __TIME__.

This micocontrollers laboratory is designed to speed up projects, and make easy and clean connections.

An Arduino Nano used as an IO expander on I2C for ESP8266. For example, add 8 digitals IO and 6 analog inputs.

Use the ATmega328P's 8-bit timer and prescaler to implement custom timed events, rather than relying on millis() or delay().

We will use our M.P.U. 6050 to control a Graphic unit or say Model Paper Plane, which is commonly known as Teapot, with our M.P.U. 6050!

Use Arduino, an OLED display and an AD9833 DDS module to create a useful wave generator for your lab.

Did your somewhat expensive ($50) soldering iron just die? Well then fix it with another one!

This project is all about making a power inverter using arduino. The Inverter produces 220VAC from 12V battery.

A guide how to control 7 segment display with Shift register as well as daisy chain them to create multi digit displays

Give 16-bit digital output or get 16-bit digital input from any Arduino pins.

AKA how to build your own laboratory vortexer without spending a lot of money.

Analyze the responses of a bandpass Butterworth and Chebyshev1 filter deployed to an Arduino Nano from the Wolfram Language.

This project is performing a faster frequency transform (FFT).
