Circuit introduction:
This circuit is a light-emitting diode automatic control circuit composed of digital integrated circuits CD4060 and 74HC138. CD4060 is internally composed of an oscillator and a binary counter with 10-level output. The oscillator can be connected to a crystal oscillator or RC. This control circuit is connected to RC. The oscillation mode is composed of R1-R10 in series and C1-C10 in series. The resistance of the resistance in series is the sum of the resistance of each resistance. The series connection of the same capacity capacitor is equal to the capacity of a single capacitor/the number of capacitors, 104/10,
After the CD4060 oscillating circuit starts to oscillate, the counter counts the oscillating signal, and each binary bit of the counter continuously flips along with the counting, so that a square wave signal with a frequency from high to low is output on the pins Q4-Q14, of which Q4-Q10 Each of the light emitting diodes L9-L15 is driven to make the seven light emitting diodes flicker at different frequencies. Q12-Q14 is connected to the input end of integrated circuit 74HC138, 74HC138 is a 3-8 line decoding circuit, only 1 bit is low level at the output end at the same time. As the data at the input end changes, Y0-Y7 turns to low level in turn, thus forming the effect of a running water lamp on L1-L8. After the CD4060 count overflows, it will become 0 and start counting again. So as to realize the automatic control of 15 LEDs.
The 15-way lantern controller SMD welding practice kit has the following 10 functions, which are preferred for training, examination and competition:
Interesting - After the circuit is installed, add 4-6V power supply to get 7-way binary counting lights + 8-way running water lights, which is novel and fun.
Training - a total of 76 components (excluding pin headers), 240 solder points, easy to train speed.
Comprehensiveness - the circuit has 8 types of commonly used components, and can be familiar with using more components.
Practicality - the circuit has specific functions, Yanran is an electronic work.
Simulation - equipped with instructions for use, which can be used as a reference for competitions, selections, and exams.
Savings - can be used repeatedly after desoldering to increase the utilization rate.
Flexibility——Each component has a number, no parameters are marked, and the parameters can be adjusted flexibly.
Intelligence - the circuit can intelligently judge whether the welding is normal or not when the circuit is powered on, and the fault point is indicated by a light.
Innovation——The circuit design is novel and the difficulty is moderate. It is an original creation of Juling Electronics. Please do not imitate it.
Technical - The circuit has a unique working principle, providing a complete schematic diagram, with 10 test points, which is convenient for various tests and is conducive to improving the theoretical level.
friendly reminder:
The color of the included components may be different due to batch issues, which does not affect the use, please consider carefully!
The installation and production of DIY kits (parts) requires a certain professional foundation and hands-on ability. There is a risk of damage during the production process. After the parts are assembled by yourself, there is no after-sales service. Please choose carefully!
