Lifetime in the electronics (reason for word ‘old’ in username) world, but mostly in the repair end of the business. Very little experience in the ‘coding’ world (reason for word ‘beginner’ in username). Never could get my head ‘wrapped around’ actual ‘coding’. Tried various graphical programming (or is it called coding??) but not successful…except to light a led. Looking forward to learning how using XOD.
