You'll learn how to create an automation system to communicate 3 Arduinos via RS485.

This is a simple square-wave generator that basically uses the TimerOne library allow you to generate a PWM signal at pin 9.

Relay VS Transistor.

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

Discharge a fully charged Lithium-Ion cell through a resistor while measuring the current flowing through the resistor to calculate capacity

Program an AVR-IoT WG board externally instead of the onboard debugger. I had to workaround as I bricked my nEDBG debugger on my AVR-IoT WG.

A very simple but useful device for your lab.

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

Drop-in replacement for Arduino's serial monitor with variable watches.

This device serves for accurate measurement of small resistances in the range of 0.1 ohm up to 50 ohms.

In this tutorial I am looking at using millis function in the code. Describing the advantages it has over using delay function.

I was looking for ways to teach students the basics of PLC and found the OpenPLC project. Opensource, free and uses the IEC 61131 standard.

Another simple to build useful instrument in you lab.

Simple to build and useful instrument for your lab.

Rotary Encoder USB Control with single and double click action.

A small little console that allows you to quickly set, test, try many different actuators (e.g. servos, stepper, ultrasonic, DHT22, etc... )

Inexpensive, precision, autorange capacitance meter with a large range.

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

SNODE – is an open source library that allows to make it easy to build a multi-master serial bus network for hot-plugging nodes with sensors

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

This code performs FFT with good accuracy.

Standalone PC software to use your Arduino as an oscilloscope, supports up to eight channels, at rates up to 100 kHz.

If any of the projects you create are designed for portability or remote monitoring use, it usually requires the use of solar panels.
