BulletPoint1 : The Wheel of Fortune is a tool that first predicts where the spinning disc will stop when it stops. It can also be used as an estimate number game, electronic dice, lottery machine, etc.
BulletPoint2 : Circuit principle: The circuit is mainly composed of a pulse generator and a decimal counter circuit.
BulletPoint3 : Designed for Beginners：Special design for electronics starter to learn to solder electronics components. Soldering project kit will improve your electronic knowledge and soldering skills in practice
BulletPoint4 : Easy to Assemble： Electronic DIY kits uses safety materials, effectively avoid corrosion and wear out. Components’ names have been marked on the PCB board and the circuit design is simple. Even beginners can easily solder successfully
BulletPoint5 : Warm Reminder ：DIY electronic components kit requires buyer to assemble and welding, If you don't have any soldering experience, please read the soldering instructions and use soldering tools carefully to avoid safety problem

ProductDescription : The electronic lucky wheel achieves the same function electronically. This kit configures 10 LEDs into a circle. When the button is pressed, each LED turns light in turn, and the flow speed becomes slower and slower, and finally stops at a certain one. No more movement on the LED. If the last LED that lights up is the same as the player predicted, it means "winning". The pulse generator is composed of NE555 and peripheral components to form a multivibrator. When the button S1 is pressed, Q1 is turned on, and the 3-pin of NE555 outputs a pulse, then the 10 output terminals of the CD4017 output high level in turn to drive 10 LEDs to emit light in turn. After releasing the button, due to the existence of capacitor C1, Q1 will not be turned off immediately. With the decrease of the voltage across C1, the conduction process of Q1 gradually weakens, the frequency of the output pulse at pin 3 becomes slower, and the LED moving frequency also follows. slow down. Finally when the discharge of C1 ends. When Q1 ends, the 3-pin of NE555 no longer outputs pulses, and the LED stops moving. A "draw" process is thus completed. R2 decides the LED moving speed, and C1 decides the time to wait for the "draw".
