🛠️ Components Used 🔹 Arduino Uno – Microcontroller for processing sensor data. 🔹 HC-SR04 Ultrasonic Sensor – Measures distance using sound waves. 🔹 LEDs (5x) – Visual indicators for different ...

Distance Measurement: Measures distance using an ultrasonic sensor. LED Indicators: Displays distance ranges using LEDs (Red, Yellow, Blue, Green). Buzzer Alerts: Provides audible feedback for ...

The sensor operates at 5V for Arduino and 3.3V for Raspberry Pi, ensuring seamless integration with these popular microcontroller and microcomputer platforms.

Instead of measuring light, we measure the ambient voltage field on pin A5 and use it to detect if someone is too close to our Arduino. A5 is used as a “floating input”, but unfortunately it is very ...

Likely applications are button designs and proximity sensing. The kit’s board also includes a proximity loop which can detect the presence of a finger or hand up to 30cm away. The CapSense MBR3 ...

Those sensors include a Waveform flame sensor module, a DHT11 temperature & humidity sensor, and an IR receiver. You can see the prototype in use below, picking up the flame from a regular lighter.
