HC05/06 connection is as anytime (RX to TX, TX to RX) HC-SR501 connected to the D2 pin (Can use any other pin) The code: As you see, ony few line, the most basic serial connection, and one input pin. If the PIR sensor triggered on the pin2, the arduino send "1" with ser...
Step 1: Components! This project is very simple and we only need the following components: 1 X PIR Motion Sensor HC-SR501 An Arduino UNO and its USB cable for connection with the PC (type: A male to B male) A few male-to-male and male-to-female cables 1 X LED 1 X small or s...
/* Example code to create an alarm system with HC-SR501 PIR motion sensor, buzzer and Arduino. More info: www.www.makerguides.com */ // Define connection pins: #define buzzerPin 5 #define pirPin 2 #define ledPin 13 // Create variables: int val = 0; bool motionState = false; // ...
But, it can be done using the Universal Telegram Bot Library: https://github.com/witnessmenow/Universal-Arduino-Telegram-Bot And yes, you need wifi connection. Regards, Sara Reply Ronalene Romero August 31, 2019 at 2:55 am Hello! Is there any substitute for the 2n3904 transistor? Reply ...

The examples included in both the Arduino and Python libraries will freeze if the Qwiic PIR does not acknowledge on the I2C bus. The most common cause of this is a poor or incomplete connection either using the Qwiic connectors or PTH header. Check your Qwiic cables for a secure connection ...
Hc1030|Enhance your DIY projects with the HC-SR501 Adjust IR Pyroelectric Infrared PIR Motion Sensor Detector Module. Ideal for Arduino and Raspberry Pi, this sensor is a versatile addition to your kits.
Connection diagram The connection diagram of this device to the ESP32 is really simple, since we only need to connect the data pin of the sensor to a digital pin of the microcontroller, as indicated in figure 1. Figure 1– Connection diagram between ESP32 and PIR module. ...
green or blue so they work better with only the 3.3v output) and a 220 ohm resistor (any value from 100 ohm to 1.0K ohm will do fine) to theoutpin as shown. Of course, the LED and resistor can swap locations as long as the LED is oriented connection and connects betweenoutand...
