Digital Electronics Course

This Digital Electronics Course is designed to give a 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.City & Guilds Diploma in IT Systems Support Available

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 4th September, 2023 at 7.00 pm. Course fee is €800 (€100 Booking Fee + Balance of €700)

The course will be delivered through blended training consisting of 10 virtual classroom sessions including assessments and examinations (multiple choice for City & Guilds and written for H-Tech Training). (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 consists of breadboard, multimeter, oscilloscope, battery and connectors, components including resistors, LEDs and ICs. Trainees will build various projects as part of the course. The kit will remain the property of the participant (please contact us for details of training kit cost). The kit forms an integral part of the course, so full course fees need to be paid at last 10 days prior to course commencement to allow time to ship the kit in time for the course.

In preparation for this, we plan to have a quick informal free online meeting on for about an hour just to make sure that people get connected in 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 (logon IDs, etc) will be sent before the Informal Induction session. Please let us know by email if you are available to attend the free sessions as this is an ideal opportunity for you to learn about attending the course and completing the assessments to obtain the certificates.
