Procedure of assembly wiring
of a-stable multivibrator
It is necessary to do endurance to make a circuit. I describe an implemented procedure below. There are many paginations of the explanation, but it is not terrible work if the point can be understood.
The position of the hole is expressed in the figure and alphabet for convenience of explanation.
I decide the position of the part by the position of previous part. 2 holes up, 3 holes left from previous part like that. So, the mounting position of the first part is important. When you mistake first mounting position, it has mistaken all after that.
Up to here,
all the parts could be fixed on the printed board.
Next is the wiring that used tin coated wire.
Up to here
the assembly, wiring of the circuit finished.
Check of wiring
Next, confirm the normal connection of the complete circuit. The assembled circuit has the possibility that there are mistakes like loose soldering. Loose soldering does not find just it looked. There is a mistake to find when working a circuit, too.
It is OK rather than the way of my mentioning. Confirm in the appropriate way which you think of.
In case of connection check, confirm between each component lead as much as possible. When confirming with soldering part of the wiring side, loose soldering sometimes can not be found.
The check of wiring finished.
Next is an operation confirmation test.
Operation confirmation test
Yet, IC1 does not mount to the IC socket.
Are red and green LED flickering alternately ?
With over the assembly, wiring work of the circuit are completion.
