    Arduino controlled light dimmer

    yes, most likely. it has an RMS of 1.5 amps but it may be hard to put a hetsink on it so best not push it to its max

    if your load is not more than 220 Watt that should be fine. Make sure to put a heatsink on the TRIAC as well

    depends on your load

  • Send sensor data (DHT11 & BMP180) to ThingSpeak with an Arduino, using cable or WiFi (ESP8266) or use ESP8266 alone (UPDATED AUGUST 2016)

    where I say "try this code" the wrong link got inserted. Should be this one https://github.com/volca/cactus_micro_trial/blob/m...But again, I have some doubts on that code

    It has been a while, but as far as I recall I had the ESP on the hardware serial. The communication with the Serial monitor over pins 2 and 3 is through the softwareserial library.Now if you look at the program you see that you can switch the debug (i.e. what is being sent to the Software Serial) on and off. That is so that when it is all werking, you do not need that part of the code anymore.What you see in your 'Serial Monitor' depends on what port you choose. So suppose you would not connect the ESP8266 and connect an USB cable to the Arduino and subsequently look in your serial monitor, you would see what is being sent to the ESP8266, If you would connect your computer to the software serial port (e.g. with an FTDI) you would see what your arduino prints as debug messages (a long ...see more »It has been a while, but as far as I recall I had the ESP on the hardware serial.

It is the sign the ESP8266 comes back with a message, not the ArduinoAs I found and find communication with the ESP8266 via AT commands rather cumbersome and as the ESP8266 is a microcontroller in itself, I have given up on combining it with an arduino but I understand your reason why.Now one of the problems in having yr arduino comunicate with an ESP8266 is baudrate, in the early days supposedly there wereesp8266 modules that had different baudrates. Try change that.Also, make sure not to feed the ESP8266 from yr arduino, it needs a decent psu preferably with somewhat of a buffer capacitorIf you do not have an ftdi handy, remove yr esp8266 and attach a usb cable to the standard serial port and see what commando's are being sent.You said that if you "normally check' the esp with yr serial monitor... can I presume that you then have it connected to an FTDI cable? What speed are you using?Although it can happen that maybe Instructables corrupts the code, I copied it from instructables again and compiled and run it, that did fine (although I didnt have an esp connected to it). Nevertheless, it could be that somewhere a mistake slipt in so I'd say try this code. Mind you though that it is using different software serial pins. AND as far as I can see is using the software serial for ESP8266 comunication and I cannot garantee that code is actually working.Also, you will find some problems connecting to an ESP8266 discussed here.

    When is the Action figure coming

    indeed. i agree, I doubt they really would start brewing for say 700 guests.More like: "Hey they sell some cheap alcohol in this drugstore, it is even 40% m..me..meth..methyl, well i dont know what that is but here it says 'alcohol'. Fully agree, home made alcohol even if it would contain say 2% methyl alcohol would still contain enough ethanol (as antidote) to compete on receptors, though I wouldnt advise drinking that on a regular basis. Starting from water and sugar renders factually no methanol and lets not forget that your colon (well anybodies colon ofcourse) is pretty good at making metanol as well, there wld probably be more methanol in a 2 day old apple pie than in a sugar based worth destillate

    As an other reader pointed out the amount of methanol will be very small, well that is true as long as you start with a grain or sugar based wort, in a clean fermentor with a yeast culture from a well aereated source. That will result in small/no methanol formed. The reaction formula just doesnt have it.Until maybe you start using any ingredients that contain pectin. Fruits for instance. Pectin when fermented will yield methanol. Distilling it will not only increase the ethanol content but also the methanol content.Will that pose a danger? I dont know. Sure, the first distillate run off will be the most concentrated in methanol as methanol has a lower evaporation point but I have no idea if this would come to toxic levels. Also realise that ethanol is a natural antidote for methanol...see more »As an other reader pointed out the amount of methanol will be very small, well that is true as long as you start with a grain or sugar based wort, in a clean fermentor with a yeast culture from a well aereated source.

    Arduino controlled light dimmer

    I think that if you have those normal classic xmas lights in series on a string, then it doesnt make much difference which one you are using. As long as you keep the TIC cool it can take quite a load. If it are lights that work with a transformer than the PWM circuit is not suitable.With a transformer the TRIAC circuit is not ideal but it will most likely do the job.Merry xmas

    then most likely a hardware problem. Please check and recheck all yr connections

    You mean that it is a 12 Volt halogen lamp that is attached to a PSU that goes into the grid? and that PSU is labeleld as 'dimmable'.If it is for a traditional TRIAC dimmer then you will have a good chance that this circuit will do the job

    looks good sureshmali. Obviously you added a bit too it :-)

    I think you mix up a couple of things a pwm dimmer has no zerocross detector.The circuit you were seeing was working with a TRIAC (it might have well be one of my other circuit I published here) and uses Phase cutting. That is why a zero cross detector is needed.This circuit here works completely different. I havent had any flickering

    Arduino controlled light dimmer

    well that strongly suggest indeed that the problem is in your hardware. I cannot see anything wrong with yr circuit. When you tried the original program, did you include the LCD that I see in your schedule? Or was it just the program without any additions? Could you recheck all connections and soldering joints?

    Well ofcourse the signal doesnt need to go through zero ofcourse, just be low enough to open the 4n25 and if you trigger on the rising or falling flank you would still get an interrupt, but you would only get an interrupt for half of the cycle

    Arduino controlled light dimmer

    circuit looks OK. I am not sure if I asked before but did you try the original dimmer demo from the instructable? did that work properly? That would be very helpful to see if the problem is in yr software or your hardware

    no I didnt have any of those problems. It is important though to have a clean PSU as the grid is full of noise whether Triac induced or not.Anyway, I never had any problem

    you would only have one phase and therefore you wouldnt have a zerocross, just a signal that lingers at zero for half of the cycle time.You can use 1 60k but it would need to be of the double wattage that the 30k resistors are. That is one reason, The other is that by using 2 resistors the full 220 signal would be kept out of the PCB as much as possible

    Good. I hope it is of some comfort that I also lost hours on that error :-)Be careful updating your libraries, I think the error is still present

    Pierce, let me start with yr last question. If you programmed any program in your esp, the AT instruction set is gone.With regard to yr 1st question: indeed you cannot upload anything to your arduino if you have something else attached to the serialport. It is not the intention to keep uploading the program. You upload it once.to be able to connect the esp8266 and being able to debug the program defines a software serialport as well.Having said this. Currently i would not attach an arduino to an esp8266 anymore as the esp can usually handle it alone

I saw prices of 1.84 USD. only need to add a 30 ct adapter plate.the price of 5USD at volume rate is even higher than the wemos d1 mini at aliexpress that includes an usb plus voltage regulator plus pin headers.So if you are new at this, check aliexpress, not just Volumerate.com

    you only need one circuit for the zerocross interrupt.if you want more lights you only need to copy the MOC3021+Triac part.have a look at my 3 lamp dimmer.

    it is not too much to handle for the arduino, but just know that the first program is a demo program that spends most of its time in a delay loop. If you want to do something else you need to replace he delays with some sort of timer function. Also in writing yr program keep in mind that there is an interrupt 100 times a second

    I think that if you remove it and do not use a regulator your chip will not get a Vcc voltage anymore. Mind you, if you do NOT use a voltage regulator, the Vcc pin is where you put your 3.3 volt and it goes directly to the V+ of the esp chip. When you solder in a regulator and put 5 volt on the Vcc that 5Volt still goes directly to the V+ of the esp chip, so you need to interrupt that connection so the 5V doesnt go immeditely to the espchip but first to the regulator in and from the regulator out to the chip. That interruption of the powerline is made with that 0 ohm resistor.Therefore it is not a matter of ' just leave it' but rather 'you must leave it'.It does connect to somewhere: it connects the Vcc pin to the V+ of the module.On the other hand... if you put in the regulator you ...see more »I think that if you remove it and do not use a regulator your chip will not get a Vcc voltage anymore.

    the connection between arduino and esp8266 is always TX-RX and RX-TXthe channel key should not have brackets around it.In al honesty, it nowadays is a bit of a waste to use en Arduino in combo with an ESP8266 as the ESP8266 can do it alone and in fact it is easier to program as well.

    thanksDepending on the load yes a heatsink is advisable.Snubber circuits indeed need to be able to deal with the spikes going through them.I am surprised you had to resort to the analog pin, you must have changed the program then as there is no interrupt on the analog pin, but ofcourse polling is always possible

    johsim in the time I wrote this instructable I thought it would be beneficial to people if I added some codes besides the basic program. But it is a long time since I tested that specific program as I didnt want to use any buttons. Now it is very well possible that in putting the code on this webpage something went wrong. I took a quick look and it seemed OK, but If you p, me your email address (or leave it in the comments if ok with you. I will send you the original code. That however also has an LCD section in it but you can just ignore that.

    the minimum load I tried was 40 watt and that was without problem. whether you can dim LED lamps largely depends on the LED lamp. Many dimmable lamps need dedicated dimmers, but if these are LED lamps that are for what is called a 'traditional' dimmer you have a good chance of it working

    Arduino controlled light dimmer

    That is good to know. The quality of the zerocross pulse is depending on the 33k resistors. If they are smaller in value the pulse will rise faster and be thinner. I am sure it is possible to calculate the width of the pulse, but I didnt. The full period is 10msec and I do recall on measurement the pulse was less than a milisec. Yet, in interrupt terms that still can be huge.I never encountered any problems, but noise on the powerline (or probably any other line) can cause flickering. A good start is a good quality PSU with good decoupling.Adding a fast schmitt-trigger is definitely an option too in certain cases

    when testing from another server I sadly get the message that Mosquitto_sub 'is not installed' yes, I amusing the proper ip after the -h option.Please help me understand: I need to type that command from another system and I add the ip from the system where i put the MQTT broker, but then isnt that error understandable, because it will first look at the current system (on which mosquitto was NOT installed) before it even gets to the ip on which it was installed, so am i really understanding you correct in how to run it from "another system"let me clarify, I have Mosquitto installed on a raspberry that hangs on 192.168.1.102.Then I go to my desktop and typ: mosquitto_sub -h 192.168.1.102 -t armtronix_mqttThen I get an error telling me mosquitto_sub is not installed, but ofco...see more »when testing from another server I sadly get the message that Mosquitto_sub 'is not installed' yes, I amusing the proper ip after the -h option.Please help me understand: I need to type that command from another system and I add the ip from the system where i put the MQTT broker, but then isnt that error understandable, because it will first look at the current system (on which mosquitto was NOT installed) before it even gets to the ip on which it was installed, so am i really understanding you correct in how to run it from "another system"let me clarify, I have Mosquitto installed on a raspberry that hangs on 192.168.1.102.Then I go to my desktop and typ: mosquitto_sub -h 192.168.1.102 -t armtronix_mqttThen I get an error telling me mosquitto_sub is not installed, but ofcourse i get that error coz it isnt installed on my desktop but on 192.168.1.102So I am a bit at loss what that command is supposed to do, or am i now completely misunderstanding it

    Good article. just a few remarks:mosquito_sub –d –t armtronix_mqttshould be mosquitto_sub –d –t armtronix_mqttif directly copied from your text it comes back with '–d' not being a valid parameter. That is because the '–d' should be '-d' same for the 't' parameter

    I am guessing your water pump is inside your PVC reservoir?

    looks great. it might be a bit overkill to use a raspberry and an arduino Mega just for irrigation but hey, who care :-)I have done many irrigation projects and I really like your set up

  • Send sensor data (DHT11 & BMP180) to ThingSpeak with an Arduino, using cable or WiFi (ESP8266) or use ESP8266 alone (UPDATED AUGUST 2016)

    Tnx, maybe i could split it in different projects, but I thought make it a one stop place for Thingspeak. I will see if maybe I can clarify the different sections a bit more

    AC PWM dimmer for Arduino

    it works with incandescent. In order to change my circuit: take out all the parts except the bridge and the optocoupler, get a MOC3021 a fet and a couple of resistors and build this: http://www.instructables.com/id/Arduino-controlled...That works with some LED lamps, usually the traditional dimer type. I am not sure if the giesberts circuit will work but I can see some complications
