In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...

While Arduino traditionally uses C++ like code, you can actually program and control Arduino boards using Python through a powerful protocol called Firmata. This comprehensive guide will show you ...

The TMP36 is an analog temperature sensor that provides a voltage output directly proportional to the temperature. It is simple to interface with the Arduino Uno and can measure temperatures from - ...

This sensor is built for detecting ppm of certain gas molecules, such as VOC, ethanol, ammonia, Hydrogen sulphide, etc. This sensor can't distinguish different gas molecules. Please use the table ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

Finally, the CO 2 , temperature and humidity sensors use Texas Instruments OPA2336 dual op amps to amplify the sensor signals for optimum dynamic range for the Arduino ADC inputs. See Figure 5 for a ...
