MOTOR DRIVER L293D FOR DIY ROBOT KITS MADE BY SDTECH ROBOTICS L293D MOTOR DRIVER FOR 5-12V motor

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

It's an elevator with automatic doors. The code has two FSM, one for the motor that makes it go up and down and one for the automatic door.

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

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

This code performs FFT with good accuracy.

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

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

Goodbye calibration! Digitization of pH test paper! This is a pH meter that reads the color of the pH test paper.

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

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

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

Program 6 ATtiny85/13A at the same time with this custom programmer board.

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.

Controlling power to the system using alarms based on voltages!

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

There are 20 predefined wire sizes to choose from and/or one can also enter in custom sizes including their bobbin size.

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... )

This is my version of a data logger using a INA219.

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

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!

Timer for Arduino pins controlled by Serial monitor
