int sensorValue = analogRead(A0); To change the values from 0-1023 to a range that corresponds to the voltage the pin is reading, you'll need to create another variable, afloat, and do a little math. To scale the numbers between 0.0 and 5.0, divide 5.0 by 1023.0 and multiply that by...

How does the INA219 sensor work? Before we can use the INA219, we have to make sure that we understand how the sensor is working. To describe the functionality of the sensor, we go step by step over the simplified schematic of the INA219 which you see in the following picture. The ...
const int ledPin = 13; // LED connected to digital pin 13 const int sensorPin = 0; // connect sensor to analog input 0 void setup() { pinMode(ledPin, OUTPUT); // enable output on the led pin } void loop() { int rate = analogRead(sensorPin); // read the analog input digital...
The workflow is flexible and intuitive. Start by designing the product hardware on the schematic by adding electronic shields, sensors and breakout boards via the peripheral gallery. Then use the controls gallery to create the front panel, adding and placing dials, buttons, charts, etc. in the ...
Introduction TheTCS34725 I2C arduino color sensorhas a high sensitivity, wide dynamic range, and includes an IR blocking filter making it an ideal color sensing solution for use under varied lighting conditions. The TCS34725 color sensor also includes four ultra-bright LEDs to allow the sensor to...
One lesson was that I could perform all sensor data computation and visualization in the browser, so I don’t need much in the way of microcontroller capabilities. The ESP32 I used for AS7341 web UI was overkill. All I needed was an I2C bus and WiFi, so I could easily drop down to...
