An easy enough kit for practice or beginners. The battery box is for 3xAA so only gives a max 4.5v meaning that when you turn the potentiometer down it goes so dim it can almost disappear, using up to 6v will prevent this. The blue kit that I chose is a pleasant colour on the eye and the kit came with 3 extra LED's so some spares for the box as well. I've also uploaded a video of it in action and some pictures in it's different states. For the price it won't disappoint.

egyszerű áramkör, jó gyakorlás kezdőknek... az 5 éves kisfiam imádta, mikor összeraktuk anyák-napjára... azóta mégegyet akart össze-szerelni-forrasztani...

O kit estava completo. Instruções e esquemas estavam disponíveis através de um link do meu histórico de compras na Banggood. O projeto levou-me cerca de uma hora para montar. A fonte de alimentação não incluída não era um problema para mim e não era realmente esperada para o preço. Podia ter usado um bom conector fino para os cabos da fonte de alimentação... 3 LEDs adicionais na embalagem :) Quando defino a taxa de pulso e o tempo real do batimento cardíaco, os LEDs não escurecem muito. O tempo de pulso é diretamente proporcional ao brilho dos LEDs. Geralmente muito satisfeito com este produto. Tenciono usá-lo para um presente de namorados :) <3

Kit was complete. Instructions & schematic were available through a link from my purchase history in Banggood. project took me about an hour to assemble. Power supply not included was not a problem for me and not really expected for the price. Could have used a nice slim connector for the power supply wires... 3 Extra LEDs in the package :) When I set the pulse rate for and actual heartbeat timing, the LEDs don’t dim very much. The pulse time is directly proportional to the brightness of the LEDs. Generally pretty happy with this product. I intend to use it for a Valentines Gift :) <3

Fairly straight-forward child-friendly soldering project. We soldered a bunch with a group of children as father's day present. The only disadvantage is that the IC does not have a footer. They worked like a charm!
