    Learn how TRIAC work and how to control AC voltage. Detect the zero cross and synchronise the firing pulse with it. Use DIAC to control the gate of the TRIAC. Finally we add bluetooth connection adn dim an 220V AC light bulb.

    Love your way of clarifying the concepts behind your project. You mentioned briefly that you can use step down trans say 230/12 volt. Is that mean that if I provide 12 volt to your circuit all the components will function with NO CHANGE. of course I will use an LED as a load instead of the 220 volt lamp.

    VERY IMPORTANT SAFETY ADVICE!!
    In english here! En español abajo!
    Good circuit men I built something similar in the past. I need to clarify one point that is very important. Take care with inductive loads (motors, CFL...) especially with heavy ones!!, because triacs and also diacs have dv/dt specs, it means that if you change the voltage very fast the triac (or diac) can be damaged or even worse, destroyed :S. (When you switch ON/OFF a inductive load voltage spikes can happen). Also if you connect a heavy load (which demands a lot of current) there will be more power disipation on the triac/diac because Power = Voltage x Current, this means that the triac/diac can get very hot quicky and this will cause the destruction of the component. Check the datasheet of the component and put a good dissipator to prevent this ^^.
    As bonus! ^^ To prevent problems with heavy inductive loads you should use a snubber circuit. Designing a snubber circuit requires more knowledge in electronics but if you are interested I invite you to search in google snnuber circuit for diacs/triacs ^^.
    I hope you, people, understand my explanation :), I'm from Spain too :P. See you!! and have fun with safety electronics!! ;D.
    EN ESPAÑOL!!! para los hispanohablantes! ;)
    Buen circuito tío! construí algo similar en el pasado. Tengo que aclarar un punto muy importante cuidado con las cargas inductivas (motores, CFL...) especialmente con las "pesadas" (bobinas grandes tipo transformadores, motores grandes...) ya que los triacs, (tambien los diacs) poseen especificaciones dv/dt lo que significa que si se cambia el voltaje bruscamente (muy rápidamente) el triac/diac puede resultar dañado, o aun peor, destruido :S. (Cuando conectas/desconectas una carga inductiva se pueden producir estos cambios rápidos de voltaje de los que hablo). Ademas de esto, si se conecta una carga que demande mucha corriente (no tiene porque ser de tipo inductivo), habrá mas disipación de potencia ya que Potencia = Voltaje x Intensidad, lo que hará que el triac/diac se caliente muchísimo y esto puede causar su destrucción. Recomiendo mirar el datasheet, mirar que potencia soporta el componente, que intensidad y que voltaje ^^. También una buena idea es poner un buen disipador para prevenir estos incrementos de temperatura en el componente.
    Como bonus!! ^^ Para prevenir problemas con cargas inductivas "pesadas" convendría usar un circuito llamado snubber, es como una especie de filtro que evita picos de voltaje, pero para diseñar uno hace falta tener conocimientos mas avanzados de electrónica, os invito a buscar en google snubber circuits for triacs/diacs (circuitos snubber para triacs/diacs).
    Bueno después de todo este pedazo de comentario, espero que nadie se electrocute, se cargue la instalación eléctrica de su casa... jaja Disfrutad de la electrónica, si vais con cuidado nada malo pasara! un abrazo gente! ^^.
    Para el Autor del vídeo! me identifico contigo yo también estudio ingeniería Electrónica y ya estoy casi acabando tengo 24 años! jaja Un abrazo sigue así y cuidado que no se te electrocuten los subscriptores! jaja :P

    Hi, I designed the same circuit but I am getting only positive pulses at output, the negative half is completely clipped. Can you please guide what the issue is. The output of MOC3020 provides pulses in both positive and negative halves at the output but as soon as I connect those with gate of TRIAC, only positive pulses are there. What would be the reason (I already have replaced all the components).
