Demo - Quiz Buzzer - www.kitronik.co.uk

Two people (or two teams) can used the quiz buzzer to show who pressed their button first. When the button is pressed the buzzer sounds and either the red or green light is illuminated to show who was fastest.

Instead of the red and green lights can I set it up to light LED Christmas lights?

I have soldered together the quiz buzzer kit, I am a beginner, and safety is first to consider and strongly apply,

I had to resolder a few times until i managed to solder the joints to a satisfactory level, I am worried that I might burn out components, I read the booklet about 5 times and took notes, on a sheet of paper, I drew out my version of the diagram, and detailed each component in my written form too, while observing the very useful literature that came with the kit,

I challenged this task, with not rushing to solder straight away, I was abit concerned about the size of tip on my solder iron, it being to wide, and could result in failed soldered joints, I checked this, but I did not have a smaller tip. any recommendations when soldering on a small pcb board and what size tips would be most ideal for these soldering tasks.

I have 3 pairs of glasses, and can't see well the pcb.
the pcb is too small for me to follow, this comes with a printed pcb. can you use a plain pcb a larger size and solder the components onto it,

the only problem is the traces of the wiring which must be soldered to have a circuit. Any suggestions if I want to use a plain pcb . with more space. thank you
