20210505· Hello, I am making a water sensor that turns on a speaker and LED when water is detected. That information will then be transmitted to a WiFi server, which an Android app will then read and notify the user. The WiFi server works how I want it to currently, but the issue I am having is with my speaker. What I want to be happening is, when water is detected, the LED and speaker will turn on. If ...

Some Arduino boards like UNO, MEGA and DUE, come with AC socket which can be used to power the boards and to supply additional voltage if needed. A power supply adapter that provides from 7 to 12V (Volts) of DC (Direct Current) is required. The adapter is plugged onto the wall socket and the other end goes directly onto the board''s AC socket.
20120728· 20210506· Hey guys I''ve been having trouble editing some code with arduino and I was wondering if you guys could help me. I am trying to hook up a PIR sensor so that it turns on an indicator light. The indicator light will then stay on until I use a pushbutton or a switch to reset it. Then the PIR sensor can sense motion again to turn it back on. I ...
You can reset your Arduino board, , start your program from the beginning. You can reset the UNO board in two ways. First, by using the reset button (17) on the board. Second, you can connect an external reset button to the Arduino pin labelled RESET (5).

In this project, we are going to implement CAN Bus communication with MCP2515 module to communicate between two Arduino for sending temperature data from DHT11 sensor. This module uses 5V as operating voltage and has pinout configuration as shown in the following table. The result is as shown below: YouTube. Arthur.
20200110· For example, we can use an Arduino microcontroller to receive the soil moisture readings, which can then automatically turn on sprinklers when moisture is insufficient. Soil Moisture Sensor: Principle of Operation. A Soil Moisture Sensor can either use resistance or capacitance changes to measure the water content of the soil. To further understand both working principles, we’ll take a look ...

There are two way to reset Arduino by coding: hardware reset and software reset Hardware Reset Arduino by coding Connnect an Arduino digital pin to RESET pin Config the digital pin as a digital output pin by using pinMode () function.
Heart Rate can be monitored in two ways: one way is to manually check the pulse either at wrists or neck and the other way is to use a Heartbeat Sensor. In this project, we have designed a Heart Rate Monitor System using Arduino and Heartbeat Sensor. You can find the Principle of Heartbeat Sensor, working of the Heartbeat Sensor and Arduino ...
20191022· So you first really need to "condition" the output of your sensor so that it gives a clean pulse that can reset the ESP8266. Then you need to "gate" that signal so it can only get through while the board is asleep. For conditioning the shock sensor signal I would be inclined to use a 55 timer in monostable mode.
Arduino Reset. You can reset your Arduino board, , start your program from the beginning. You can reset the UNO board in two ways. First, by using the reset button (17) on the board.

20210505· 1) It all works fine when it''s not reading the temperature sensor. Generic numbers can be sent to COSM all day and night with no issues. 2) Changed out the 10k ohm resistor to the recommended resistor with the temp sensor. Arduino still stops sending out put requests after an hour so. 3) Used the DallasTemperature library, along with the ...
20210506· I have interfaced a DHT11 temp and humidity sensor with the Arduino. It works fine, but always the first 2 readings are garbage values. How can I filter out or omit the first two readings so that I get correct readings every time? It is crucial that I get correct readings every time because my further calculations mess up if I get incorrect values!.
20210506· Hi Guys, I''m new at this forum. I''m building a motion sensor for my front door. Got a Partical Photon with an Grove Shield and a Grove PIR Motion sensor. I''m checking the highs for movement, but the wifi chip on the Partical interfere every 2/3 minutes (1 high). Googled a lot about this, but couldn''t find a solution (other than board with ethernet or a different sensor).
