you can control Robotic Arm remotely using many wire and wireless methods to do many tasks such as holding things and can be used in a lot of medical applications like surgery and holding micro tools which can’t be controlled with human arm, what gives a great accuracy, and similarly in industrial and agricultural applications.
If you think to buy a robotic arm, it costs you about $300, but if you try to make it yourself in addition to gain more experience in fabrication, it’ll cost you about $150, which means you provide almost the half, and its fabrication isn’t a very hard process, so what’s your choice ?
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
