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 ...

We can use the ADC of the Arduino to process the signal and we can light up some LEDs to show the intensity of the sound received by the microcontroller. The connection of the circuit is also very ...

While PIR sensors can be used with Arduino and other microcontroller boards, those best-suited for hobby use are smart enough to perform simple tasks without any programming.

Code uploadWe can now load our Arduino sketch to the RAK4631 development board.Selected the board in the Arduino IDE, as well as the correct port, and start the code uploading and flashing. You may ...

This code is designed to measure analog voltage input from pin A0 and calculate the corresponding voltage value using an Arduino board. Here's a breakdown of the code: int voltageV = A0;: Declares a ...

The ZMPT101B module is a compact single-phase AC voltage sensor module based on the minuscule 2mA/2mA precision voltage transformer ZMPT101B made by Qingxian Zeming Langxi ... You need to keep an eye ...

The supply voltage depends on the board, but the more popular ones use 9V. In contrast, you can't connect most batteries to a Raspberry Pi, as it needs 2.5 to 3A to power up (regular 9V batteries ...

Let’s use its function analogRead to measure some voltages with. AD Converters Are Not So Easy In this video we show how to configure an Arduino UNO board for precise voltage measurements. A ...
