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 ...

The project requires an Arduino Uno, an L293D motor driver, IR sensor modules, a battery, BO motors, and a hobby robot chassis. The circuit integrates sensors, motor driver, motors, and Arduino, with ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi.

Arduino project for Circuit Playground Express that automatically pauses your TV when you get up from the couch. The Person Sensor from Useful Sensors is a small, low-cost hardware module that detects ...

In this circuit, the infrared emitter IRED1 is modulated by connecting its anode (A) to ~38kHz signal yielded by D9 of the Arduino Uno (TP1) while its cathode (K) to a ~1kHz signal available at D8 of ...

Another kit called the ‘Sensor array’ contains various sensors plus an SD card module. You can use the Sensor Array to make environmental measurements and log the data on an SD card. These kits are ...
