Hi, a good friend of mine's birthday is coming up and I'd like to make him a personal gift. I have a couple Arduino's laying around: a normal one and a Nano I think. I also have a soldering kit, and there's a 3D printing fab nearby me so I can even get something custom made. He really likes Pokémon and producing music with FL Studio — he also DJ's semi-professionally. I'd really like to make something personal instead of buying something, but I have no clue what. I can code, I have an Arduino and a starter kit, I can learn 3D modeling for a custom 3D print, I can learn Gerber files for custom ..read more

I'm new to Arduino and I'm trying to make a project using vibration sensor and gsm module wherein once it detects vibrations it will notify the owner through text message. The code below does not send a text message. Can you tell me what's wrong with this code and on how I can improve it? #include <SoftwareSerial.h> SoftwareSerial sim800l(2, 3); // RX,TX for Arduino and for the module it's TXD RXD, they should be inverted int vibration_sensor = 7; int Sensor_State =1; //#define Vibration_Sensor A0 // Vibration sensor pin, connected to analog pin A0 //bool Sensor_State; // Variable to st ..read more

I'm working on a network-connected sauna solution. The main board has an Atmega328P and MCP23017 for expansion (2 pins for I2C OLED, 4 input buttons for menu controls via oled, 4 temp/humudity sensor inputs, 5 relay outputs for heaters, 1 door sensor input and a few for different RGB leds) I want the board to be modular - so some saunas can be standalone (without the networking board), and they work with just an atmega and screen - full manual controls As an add-on I want to create a web UI for the client, so they can adjust the temperature, humudity, lights etc. I was thinking of adding a R ..read more

Hi, i recently bought some “360° servos”, which turned out to be modified servos without potentiometers. Can i use them by setting a time for which the would spin? If so how? And also do you guys have any recommendations for rather than buying 4 90° servos: i want to give my arduino side of world like south or east and for it to turn to this chosen side. Are there any real 360° servos? submitted by /u/grzechowiakofficial [visit reddit] [comments ..read more

I'm using 3 max31855 modules to read temperature. They all share the same voltage line, GND line, CLK line and DATA OUTPUT line. they each have seperate lines for CHIPS SELECT. when I try reading from the sensors I'm getting correct internal reading however the celsius readings make no sense (they should be room temp). Can anyone point me to my mistake? submitted by /u/HillelLandau [visit reddit] [comments ..read more

So i want to apologize if this has been answered before, but all tutorials I find are either for on/off switches but I'm looking for real-time push button function. What I want to achieve is, to connect a real arcade button to the Arduino, if I push the button and leave it pushed, the signal will remain like that, if I release the push button, the signal will turn off. Real-time on off. The code I'm trying to use, turns the relay on but not off once I release the button. Please help me out. I'm using an Arduino uno smd with a 5v relay. // setup pins const char BUTTON_PIN = 8; const int RELAY ..read more

My engineering team developed our own custom Arduino that enables us to put an RFM9x LoRa module directly into the female headers on the left hand side of the board. When trying to use it as a sender to communicate with an Arduino Uno as the receiver, we get LoRa startup failed printed in the serial monitor. However, when we use another Arduino Uno as the sender, we are able to transmit packets so we cannot seem to understand why our custom Arduino is not able to send packets. Any help would be appreciated. submitted by /u/jonarabo [visit reddit] [comments ..read more

I am trying to set up my esp8266 with Blynk. I got a sun founder 3 in 1 Arduino kit and I am following all the instructions online on how to configure it. I am positive I have it all wired up properly but when it asks me to open the serial monitor nothing is showing up. When I try to enter commands to the serial monitor all i get it little squares. For example if i enter AT then all i get back is two little squares and nothing else. Yes I have the correct baud rate. I dont know if its a code issue or something else. I just copy and pasted the code that the website gave me. These are the i ..read more
