As we mentioned earlier, BH1750 ambient light sensor can be interfaced with Arduino through I2C bus pins such as SDA and SCL that are A4 and A5 pins of Arduino Uno. This schematic diagram shows the internal circuit of the breakout board: Connection with Arduino Uno To interface, this light...
Lecture 1.1 Arduino Shields A Arduino shields shield: a printed circuit board (PCB) that adds functionality to your Arduino Hardware: A circuit is pre-wired and sold on a printed circuit board Software: A software library is provided to interact with the hardware Benefits of Shields No wiring ...
Sending PulseThe HC-SR04 is a common sensor for interfacing with an Arduino. Using the code that is easily found in the internet didn’t work initially. I found out that a voltage divider is needed because the HC-SR04 sends 5V pulses from the echo pin to the 3.3V GPIO pins of the ...
In one of our previous tutorials, we have shown you how you caninterface LM35 Temperature Sensor with Arduinobecause it's cheap, easy to use, and requires minuscule power for stable operation. But one of the major disadvantages of the LM35 sensor is that it is analog in nature, so it's ...
