Ultrasonic Sensor Measurement: The HC-SR04 ultrasonic sensor measures the distance to an object by emitting a sound wave and measuring the time it takes for the echo to return. The sensor is connected ...

The ultrasonic sensor will emit sound waves and measure the time it takes for the waves to bounce back after hitting an object. By calculating the time difference between sending and receiving the ...

The Maker Uno RP2040 board can be purchased for $14.90 with some local distributors in Europe, India, Japan, and Egypt. They don’t sell the kit we’ve received directly, but you’ll find the Maker soil ...

What do you need to build an Arduino Speed Sensor. Building an Arduino speed detector using IR technology to measure the speed of a moving object is much more cost-effective, and it is also very ...

This Ultrasonic Sensor Circuit consists of a set of ultrasonic receiver and transmitter which operate at the same frequency. When something moves in the area covered the circuit’s fine balance is ...

In addition, you also get a matching motor controller board, a rechargeable battery and its charging circuit. Most hoverboard controllers use the STM32F103, so flashing them with your own firmware ...

For that follow the circuit below and connect the DHT11 sensor to the Arduino Uno R4 WiFi Board. Connect the power pins to the 5V and GND pins or Arduino and the signal pin to the D7 pin of Arduino.

Arduino Motion Sensor – Circuit and Working The circuit diagram of the automation device using a motion sensor is shown in Fig. 2. It consists of an Arduino Nano board (MOD1), a PIR sensor (S1), a ...
