Here you can see my new bot:
some details: Ultrasonic mounted on a servo, front and back infrared sensors, at the bottom theres an optical mouse, on the front wheels there rotary encoders.
L298N Motordriverboard and bluetooth chip.
the brain of the bot will be the raspberry pi, he has to do all calculations, mapbuidling and so on.
the arduino at back will read the sensors and drive the motors. he will send messuremant data to the pi using usb cable and serial connection.
the bot shall drive autonomously also as driven via smartphone orientation sensor, which is connected via bluetooth using the amarino2 app.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
