Digital Electronics Course Online

Digital Electronics Course


This Digital Electronics Course is designed to give practical knowledge of the type of electronic circuitry used in a modern Computer System or in any type of Computer Controlled equipment such as Photocopiers, Cash Registers, Tablets, mobile phones and many other types of IT equipment. 

Digital Electronics involves the use of Silicon chips (Integrated Circuits). The internal structure of a computer is to a large extent comprised of Digital Electronic Circuits.

Duration and Schedule

This Digital Electronics Course runs over 10 evenings (every Monday and Wednesday) from 7.00pm to 10.00pm with the next course commencing on Monday 2nd September 2024 at 7.00 pm.

A payment of €100 secures your place on your chosen course. The balance of the course fees of €700 can be paid shortly before course commencement.

Online Virtual Classroom – how it works?

The course will be delivered through 9 online virtual classroom sessions. The 10th and last session will involve the additional practical work for the course as well as the written examination (multiple choice for City & Guilds and written for Hi-Tech Training) which will take place at our training centre at 43 North Great Georges Street, Dublin 1 (completed online for non ROI learners).

During the virtual classroom sessions, trainees will have a live video feed with their instructor talking to them, doing practical live demonstrations on equipment being involved actively in the learning.

We will send out a practical kit so that trainees can complete assignments and practical work at home. The kit is the property of Hi-Tech Training and will be returned to Hi-Tech Training on the last day of the course.
(The kits may also be purchased by the learner….see the Kits Page Link for more details).
The kit consists of power supply unit breadboard, multimeter, cables, The kit consists of breadboard, multimeter, oscilloscope, battery and connectors, components including resistors, LEDs and ICs (AND, NAND, OR, NOR, X-OR, X-NOR, Inverter, Buffer, Latches, Flip-Flops, Timers, etc). Trainees will build various projects as part of the course. The kit forms an integral part of the course, so full course fees need to be paid at least 7 days prior to course commencement to allow time to ship the kit in time for the course.

* If attending the course from outside of Ireland the course practical training kit must be purchased via our online shop in time for delivery before course commencement. The equipment will then remain the property of the trainee.

In preparation for each course, we have a quick informal free 1 hr online meeting approx. 7 days prior to course commencement, to make sure that trainees get connected through Zoom properly, let them know what the virtual classroom will be like and go through any questions they may have. To join the virtual sessions, you will need a PC/Laptop or Tablet with an internet connection. Joining instructions (login IDs, etc.) will be sent before the Informal Induction session.


Learning Objectives
