Circuit Diagram. Here the Nokia 5110 LCD is used to display the Light level and distance.The Nokia 5110 LCD operates at 3.3V so it can’t be connected with Arduino Nano digital pins directly. So add ...

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

Power up the ultrasonic sensor by the 5V of Arduino and common all the grounds. Upload the receiver code to the Arduino of the Receiver and the transmitter code to the Arduino of the transmitter. Now ...

This project uses an ultrasonic sensor to measure distances in centimeters and controls a set of LEDs based on those distances. The project is designed for Arduino boards, and you can use it to build ...

The circuit was simulated in TinkerCad. This circuit can be used along with robot wheels so that they robots can change directions automatically if they face an obstacle. The circuit components are 2 ...

Arduino Uno . A Touch Sensor is a very sensitive input device that detects physical touch or proximity. The advantage of this sensor is that a single sensor is used to carry out many operations like ...

Here is the diagram of my Arduino infrared close proximity sensor. As you can see, ... In this circuit, the infrared emitter IRED1 is modulated by connecting its anode (A) to ~38kHz signal yielded by ...
