You are most welcome. It worked fine on the breadboard.
After soldering, it beeps all the time.
The soldering was very difficult and stressful, but I learned a ton.
I used a 4x magnifier. Could have used a 10x.
I only had stranded wire to use for the connections.
I have copper tinned wire but was afraid it might short out the circuit if the wires got pressed down.
I am waiting for some Kester 44 solder. I used the wider Radio Shack solder.
I used to wonder why people use such narrow solder.
I wonder no more.
I am wondering if my knock off solder iron is really setting the temp correctly.
It was set to around 350 C. When I switched to a very narrow tip, about 1/3 of it melted off. ?
My regular tip does not melt off.
Later, after I have fully recovered, I will recheck my work.
