Hello, good day. I congratulate you for the video, very well explained. My question is if the PIR sensor works well with 3.3v and according to the characteristics it works with 5v. Thank you very much and until next time, greetings. 🖖
I loved your video-it's fantastic! I'm new to this type of work and have been really frustrated with retail sensors. I want to create something just like what you did, but I need it to be battery-powered and able to communicate with Home Assistant. Can you show a project like that? Even if just battery powered would be very helpful. Your guidance would be invaluable!
i currently use several leo bodnar boards which are greeat but iv got too many switches. can i use a matrix with the leo boards? also i have several variable pot and rotary encoders too and also 8way hats and momentary buttons. how do i deal with them?
Hello. I am using a waveshare oled screen that has a different library. I try to generate an image but when i upload it, it displays the image 4 times in a single line. Do you know why it generates a code like that?
Hey bro, is there a way to get this to work without them doing this manually.....im not publishing the file to the Microsoft store..but i have a plan to distribute it, I don't want all my users doing it
#define sw A1 //name for analog pin A1 #define led1 12 #define led2 11 #define led3 10 #define led4 9 #define led5 8 void setup() { Serial.begin(9600); pinMode(led1,OUTPUT); digitalWrite(led1,HIGH); //setting led1 pin HIGH ie LED will be off according to our circuit pinMode(led2, OUTPUT); digitalWrite(led2,HIGH); //setting led2 pin HIGH ie LED will be off according to our circuit pinMode(led3, OUTPUT); digitalWrite(led3,HIGH); //setting led3 pin HIGH ie LED will be off according to our circuit pinMode(led4, OUTPUT); digitalWrite(led4,HIGH); //setting led4 pin HIGH ie LED will be off according to our circuit pinMode(led5, OUTPUT); digitalWrite(led5,HIGH); //setting led5 pin HIGH ie LED will be off according to our circuit } void loop() { Serial.println(analogRead(sw)); // reading and printing the values from analog pin A1 if(analogRead(sw) >197 && analogRead(sw) <207 ) digitalWrite(led1,LOW);// LED will turn ON else if(analogRead(sw) >248 && analogRead(sw) <258) digitalWrite(led2,LOW);// LED2 will turn ON else if(analogRead(sw) >333 && analogRead(sw) <343) digitalWrite(led3,LOW);// LED3 will turn ON else if(analogRead(sw) >509 && analogRead(sw) <514) digitalWrite(led4,LOW);// LED2 will turn ON else if(analogRead(sw) >1015 && analogRead(sw) <1023) digitalWrite(led5,LOW);// LED2 will turn ON }
Great Tutorial! I'm building this and i'm slightly new to Electrical engineering and ESPs. I'm using an ESP32 DevkitC to run a 24v LED Strip. I'm wondering which transistor to use? Will TIP120 work? Or should I get a MOSFET?
First of all. Thanks for an interesting video. I am new to Arduino and find this very useful. Second, the idea of building a keybord using this method contains a challenge. What if two contacts are pressed simultaneously. Then presumably only the contact with the lowest resistance will be read as electricity flows the path of least resistance.
@@iRicardoTM You shouldn't. Relays generate high reverse voltage spike which could/probably will fry the controlling board. At a minimum, you need a reverse diode between relay terminals. Ideally, there would be an opto-coupler isolation for control and transistor would energize the relay... and all of these are already provided on the relay module board for you.
"I'm very sorry, we have stopped accessing third-party ESP chips, we suggest you choose other chips or modules to use." just for you to know.. Tuya no more supports esp8266. Only their own chips
Hi I always get the matching function for call to 'HttpClient::HttpClient()' n error can you integrate a dfplayer that plays an mp3 during prayer times?
