Wireless Communication: Interfacing 433MHz Transmitter and Receiver Modules with Arduino UNO
0 Comments
A 433MHz transmitter and receiver pair uses Amplitude Shift Keying (ASK) modulation to transmit and receive data wirelessly. The transmitter modulates a 433MHz carrier wave with the data signal using an ASK modulator, and transmits the modulated signal through an antenna. The receiver picks up the transmitted signal with an antenna, filters out unwanted...
Real Time Heart Rate Monitoring System Using Arduino
0 Comments
This project is an Arduino-based heart pulse sensor that uses an OLED display to show the user's pulse rate. The program uses an analog heart rate sensor connected to pin A0 of the Arduino board. The code reads the sensor values and maps them to a range between 0 and 45 to create a...
