DIY Arduino Robot Arm with Smartphone Control

Posted on by

Hey peeps, Steve here 😀

Here’s a side project I’m working on in the Design FabLab to learn how to use mechanical electronics, Arduino microcontrollers and coding.

A pretty big endeavour for me as I don’t have much background in this stuff but thankfully I’ve found a great tutorial that I will be following along with to start with, then deviating and customising parts and coding later when I fully understand the workings of the default example.

Here’s a link to the website and tutorial – https://howtomechatronics.com/tutorials/arduino/diy-arduino-robot-arm-with-smartphone-control/

Below is a photo of the assembled 3D printed parts with the servo motors installed.
At this point the arm doesn’t do anything and won’t support it’s own weight but I will be working on the electronics soon enough and powering it up!

If you want to see more or get involved, maybe build one too, come and have a chat 🙂

Building a tilt control bluetooth car with processing and arduino

Remote Control Car

Overview:

This project makes use of an Arduino, a car chassis, a bluetooth module, and an android phone to make a Remote Control Car that is controlled by tilting the phone like a steering wheel. This post is a high level overview of the project and requires a solid understanding of coding.

RFID and Arduino

Posted on by

This is a basic access control project to read and use the unique IDs of RFID cards including the University of Auckland ID cards.

It uses an RFIDRC522 module that can read 13.56MHz cards and the code is based on the RC522 Arduino library found HERE. It can also write data to the sectors of blank types of these cards for offline data storage or counting, but for this project, we will just be reading the ID numbers of the cards.

Interfacing Arduino and sensors with Unity

Posted on by

Overview

For this project, we attempted to interface hardware sensors with Unity to manipulate virtual objects and give feedback to hardware.

Goals for this project; To use a sensor to control the camera position in a basic Unity 3D scene, and to turn on and off a LED, based on keyboard inputs.

This is based off a YouTube tutorial by inScope Studios.

Files used are available at the end of this post.
