Circuit Documentation
Summary
This circuit is designed to interface an Arduino UNO with a heartbeat sensor and a 0.96" OLED display. The heartbeat sensor captures heart rate data, which is then processed by the Arduino and displayed on the OLED screen. The MAHIR 12.0 power supply is used to provide the necessary voltage levels for the components.
Component List
Arduino UNO
- Description: A microcontroller board based on the ATmega328P. It is used for programming and controlling the circuit.
- Purpose: Acts as the main controller for processing data from the heartbeat sensor and sending it to the OLED display.
Heartbeat Sensor
- Description: A sensor that detects heartbeats and outputs a signal corresponding to the heart rate.
- Purpose: Captures heart rate data to be processed by the Arduino.
0.96" OLED
- Description: A small OLED display used for visual output.
- Purpose: Displays the heart rate data processed by the Arduino.
MAHIR 12.0
- Description: A power supply module that provides multiple voltage outputs.
- Purpose: Supplies power to the Arduino and other components in the circuit.
