I am new to electronics and have been trying to teach myself for over a year now, and one of my big hurdles is reading schematics. I have attached a schematic of a kit that I purchased and I am stuck. Here is what confuses me about schematics. Connections to multiple components, if it is simply connect pin 1 to ground I am fine. But when it shows pin 1 connecting to pin 8 which also connects to to +5v and a capacitor to ground I am lost.
If you look at the schematic that I attached my questions are:
If you look at the schematic that I attached my questions are:
- looking at IC on the left it shows pin 7 going to R1 which connects to C2 which connects to pin 8 which connects to pin 4 then it goes to 5v. this is where it gets confusing to me, I just don't understand the logic of how these components should be connected. I have a half dozen beginner electronics books but none of them explain how these multiple connections work.
- looking at the IC on the right same thing does pin 7 connect to 5v through R3? does VR2 connect to pin 7 and to R3 then to 5v? does pin 8 connect to pin 4? which then goes to C6 then to ground? and I am really clueless with the speaker connected to D1 which goes to 5v? and to Q1.
- but I am real clear on the IC555 on the left that pin 1 goes to ground, and pin 5 goes to ground through C3.
