AJMRTC lucky rotary DIY kit is a popular educational soldering practice suite built with NE555 and CD4017 chips. The NE555 generates adjustable clock pulse signals, while CD4017 decodes pulses to drive 10 surrounding LEDs to light sequentially. When you press the trigger button, the LEDs rotate rapidly like a fortune wheel. After releasing the button, the pulse frequency gradually decreases, the spinning slows down, and finally only one LED stays lit as the random lottery result. It helps beginners master soldering skills and intuitively learn astable oscillation, pulse counting and sequential decoding principles. All required components including PCB, ICs, LEDs, resistors, capacitors and push button are included. This listing contains 2 complete kits for student group teaching, spare backup and double fun assembly.
