Car Speed Detector using Arduino and IR Sensor. That’s all; now we are in the final stage of testing our Arduino Speed Sensor project to measure the speed of moving objects. In the GIF below, you can ...

HCSR04-DistanceMeasurement: Demonstrates how to measure distance using the HC-SR04 distance sensor module with Arduino. Keypad-Example: Allows the use of a keypad module with Arduino. Programming ...

Next steps shows how the master (Arduino) reads from the slave I2C device. Wire.requestFrom(address, 1) command expects to receive 1 byte of data from the TC74 sensor. Wire.available() waits for data ...

This isn’t about connecting a temperature sensor in your Arduino. ... February 26, 2019 at 6:32 pm Nonetheless, this is really cool! Great job and keep it up. Report comment.

As much as we love the Arduino Uno, it's not the most powerful of hobbyist microcontrollers. Fortunately, the folks in Turin have just put the finishing touches on a 32-bit upgrade with buckets of ...

Note that the sensor's baud rate is 2400bps. Table: Output Voltage versus Dust Density. To get the output voltage value, the output of the sensor should be transformed by the following linear function ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...
