A TinyML model to predict the Lithium Ion battery's life cycle within shorter time using Edge Impulse.
Project tutorial by Manivannan
Another simple to build useful instrument in you lab.
This is a simple square-wave generator that basically uses the TimerOne library allow you to generate a PWM signal at pin 9.
This code performs FFT with good accuracy.
Purpose of this project is to write a code to control coin acceptor with Arduino so it can be used in other projects

Wireless data transmission with NRF24L01
Project tutorial by Team HiBit
This library controls and drives motion of all types of bipolar stepper motors with 2 phase (4 terminals).
Project tutorial by ambhatt
This device can also be called an EMF meter, as it can measure the relative strength of a field using a scale of 10 LEDs.
let's measure the smallest resistance ever posses by any wire or any shunt. The proper use of OHM's law with practical.

The basics of measuring the current. Making a own current sensor to measure the current using voltmeter. YES CURRENT USING VOLTMETER
A simple circuit with minimal components which allows you to test the Nrf24l01 modules, range and other parameters. Just for testing purpose
Project tutorial by Electro BOY
Test transistors, diodes, thyristors, resistors, capacitors and inductors. Also identify their leads and obtain their component value.
Project tutorial by John Bradnam
It is like a mini atom bomb, In a piece of single code you will get a lot of features and I fully respect the effort of the owner.
On this simple tutorial, we will explore how to discover colors using an Arduino and the TCS 3200 sensor, displaying it on an LCD.
