Although you can obtain Hall-Effect sensors that don’t require a connection to the circuit, the one we will be using does, as the conductor whose field strength it measures is internal to the IC chip on the sensor. Measuring DC Current with the Arduino We will use both methods, invasive...
Following is a pin mapping of with ESP32 devkit DOIT board. Although ESP32 chip ADC1 has eight channels, the Devkit DOIT board supports only 6 channels. But still, we have enough analog channels for analog sensor interfacing. ADC1_CH0 >>>GPIO36 ADC1_CH1 >>>Not available on this board...
We have written a basic Arduino library for this LSM303 carrier board that makes it easy to interface this sensor with an Arduino or Arduino-compatible board like an A-Star. The library makes it simple to read the raw accelerometer and magnetometer data, and it has a function for computing...
We have written a basicArduino library for the VL53L0X, which can be used as an alternative to ST’s official API for interfacing this sensor with anArduinoorArduino-compatible controller. The library makes it simple to configure the VL53L0X and read the distance data through I²C. It al...
More complicated sensors may transmit their readings using heavier serial interfaces, like aUART,SPI, orI2C. Many of those sensors operate at a relatively low voltage, in order to conserve power. Unfortunately, it's not uncommon that those low-voltage sensors are ultimately interfacing with a mic...
direction. Only thing that doesn't work well with this chip is i2c (because it uses strong pullups which confuse auto-direction sensor). If you need to use pullups, you can but they should be at least 50K ohm - the ones internal to AVRs/FOR Arduino are about 100K ohm so those are...
• Hardware Abstraction Layer (HAL): this layer provides the low-level drivers and the hardware interfacing methods to interact with the upper layers (application, libraries and stacks). It provides a generic, multi-instance and functio...
Raspberry Pi Pico W SMTP Client Send Sensor Readings via Email BME680 Web Server with ESP32 ( Arduino IDE) ESP32 with MPU6050 Accelerometer, Gyroscope, and Temperature Sensor (Arduino IDE) This concludes today’s article. If you face any issues or difficulties, let us know in the comment se...
What happens when a sensor and a microcontroller with two different voltage meets? Without the voltage leveled down, for example, directly interfacing a 5V logic output microcontroller to a 3.3V input sensor can cause damage to your 3.3V circuit. ...
We have written a basic Arduino library for the LPS331 that makes it easy to interface this sensor with an Arduino. The library makes it simple to configure the LPS331 and read the raw pressure data through I²C, and it provides functions for calculating altitude based on the measured pre...
