最后,给UNO控制板插上电池就完成了(如图2.4所示)。 图2.4 完成安装 三、程序代码编写 点击打开“Arduino IDE”编程软件,输入下列代码(如图3.1所示): int buzzer=8; void setup() { pinMode(buzzer,OUTPUT); } void loop() { ...
Added Extended NEC Protocol macro to TinyIR by Buzzerb. Fixed sendSamsung() / sendSamsungLG() bug. Added functions stopTimer(), restartTimer() and restartTimerWithTicksToAdd(). Added rawlen and initialGap to IRData. Added ReceiveAndSendHobToHood example. Changed RECORD_GAP_MICROS default val...
The device uses an arduino uno R4 Wifi, a BMP180 pressure sensor which is on the GY-87 module. For your convenience, we present the circuit diagram used below:Schematic for the Portable Arduino Altimeter This is the code for this project, for your convenience. 1 2 3 4 5 6 7 8 9 ...
You could use something like a piezo buzzer to alert you if the temperature falls outside a certain range for example. Throughout this tutorial, I will show you the basics of connecting the DS18B20 to the Arduino correctly. I will also be adding some LEDs to demonstrate the circuit & code...
After you run out of numbers use letters, there are many and this method will allow you to control a lot of LEDS, or lights, or buzzers, or locks, etc. What if you want to control something that does not have a simple on/off status or send data that is not simple binary. In th...

For a project example, you can build a Parking Sensor with LEDs and a buzzer. If you are a beginner to the Arduino, we recommend following our Arduino Mini-Course that will help you get started quickly with this amazing board. If you like Arduino, you may also like: Arduino Step-by-...
hold the sensor in their hand. The buzzer was also great to test because we could change the pitch and the duration of the sound, and even make simple songs. You could even get fancy playing songs from this Github repository on the buzzer:https://github.com/robsoncouto/arduino-songs ...
