Sewer Drain Shield – Circuit and Working Fig. 1 shows the circuit diagram of the proposed drain shield for smart cities. It is built around an Arduino Uno board (MOD1), GSM module SIM800L (MOD2), an ...

This repository contains the Arduino code and circuit diagram for an autonomous obstacle avoidance robot. The robot uses an ultrasonic sensor to detect obstacles and navigate around them.

Step 3: Making the Circuit Now, as we know how the components work, let’s go ahead and assemble theses components together and make a circuit as shown below. The Ultrasonic sensor is powered by 5V ...

An ultrasonic range finder is a useful tool in a variety of real-life and robotic applications, such as in obstacle-avoidance and distance-measurement systems. The ultrasonic range finder measures the ...

Arduino UNO circuit board [8] and an HC-SR04 ultrasonic distance sensor [9] were used for data collection and are shown in Figure 2. Arduino UNO was placed on upper face of top plate and ultrasonic ...
