This Homemade Robot with Camera projects illustrate the capability of some basic materials to build a robotic physical structure. The system is driven by Arduino boards with NRF24L01 wireless modules.

[Ralph] wasn’t satisfied with the required 5 control pins to drive his nrf24l01+ transceiver module, so he used this circuit needing just 3 pin using an ATtiny85. One of the key components was to ...
