Movable platform based on Arduino UNO
Movable platform based on Arduino UNO
This is a widely used open source microcontroller board based on the ATmega328P microcontroller. It includes everything you need to work comfortably with a microcontroller: 14 digital inputs / outputs (6 of them can be used as PWM outputs), 6 analog inputs, 16 MHz quartz resonator, USB connector, power connector, connector for programming inside the circuit (ICSP) and reset button. To start working with the device, simply apply power from the AC / DC adapter or battery, or connect it to a computer with a USB cable.
The operation of the module is based on the principle of echolocation. The module sends an ultrasonic signal and receives its reflection from the object. By measuring the time between sending and receiving a pulse, it is easy to calculate the distance to the obstacle.
