You can then power the microcontroller from a 3.3V source (the 3V3 output on the board should work) and connect the sensor directly to the MCU. Look up "Arduino on Breadboard". Go to Tools -> Board ...

It combines an Arduino-compatible processor with a light sensor, a temperature sensor, a 3-axis accelerometer, a joystick, a set of pushbuttons, a slider, an RGB LED, and a buzzer.

NTE30116 Tinted Blue 5mm Infrared LED Emitter (940nm) SM0038 Photo Module for PCM Remote Control System (38kHz) The principle of this setup is somewhat simple and self-explanatory. In this circuit, ...

This project is designed to simulate the traffic light system used in Formula 1 races. It uses an Arduino Nano ATmega328P connected to a breadboard to control the LEDs representing the traffic light's ...

Before opening the Arduino software, wire up the Arduino according to the circuits page using the 8MHz minimalist breadboard circuit but with a 10k pull-up resistor on the reset pin (physical pin 1).
