Hello,
I'm new here and this is my first post.
My name is Daniel and I'm an Automotive Electrical apprentice and a starting to delve into the smaller electronics such as circuitry, etc.
I have recently purchased a Jaycar Project book with small component kit to put all the projects together and am stuck on a few oscilating circuits atm.
Whether it's the alternating flashing leds, random dice or the siren circuit. The circuit will not oscillate properly.
I did manage to get the alternating flashing leds to run properly by swapping out a resistor for a potentiometer and tuning it down in resistance so they would flashing equally and slow enough.
But I am really getting sick and tired of these circuits not performing how they should, straight off the bat.
I am checking and rechecking my circuits and they are all wired correctly.
So I have just put the below circuit together and all I am getting is a constant tone from the speaker. That is it.
These are the first experiences I have had with transistors and I have always found them the most difficult part of electrical.
The main reason for me is that there are so man different explanations for them that it's hard to keep a solid theory in my head. I don't even bother with my trade teachers as my boss has probably forgotten more than they know and even my boss gets lost in his bullsh**.
If anyone here could help me out that would be great. I hate NOT knowing why something is performing the way it is.
I plan on getting through this project book and then once I have a good solid understanding, moving onto my arduino uno kit that I have sitting here.
