Free Test Apps

On this page we have developed a number of free App Developer programs which are useful devices/systems in themselves. There are many uses of App Developer but to start with we have focussed on test: we want to provide you with a range of really great applications to allow you to create a superb PC based test environment for developing electronic products and for test on the factory floor and in the home.

You don’t need a copy of App Developer to take advantage of these apps. The Application Programming Interfaces and the Executable version of the programs allow you to run them from any Windows PC or tablet using the low cost hardware provided. Of course we would love it if you would buy a copy of App Developer and customise the applications for your own use.

Each one of these projects has a section in our Forum where you can post questions and improvements you have made.

Component tester - Arduino, USB

component tester
Hardware: Arduino Uno - Requires breadboard and several resistors

Connection: USB

Description: this fantastic project uses an Arduino Uno with 5 external resistors to provide you with a testing facility for resistors, capacitors, inductors, transistors and diodes. The programme will tell you the value, whether the component is working or not, and will even tell you the connections of the transistor or diode.
