ICStation Team introduce you this wireless transmission system based on ICStation Mega 2560 and UNO R3 compatible with Arduino. It uses DC5V working voltage. When there is someone pressing the keys, the sending system will send the value of the keys to the receiving system by NRF24L01 wireless data transmission module. The receiving system will display the value of the keys on the LCD1602. The main function of this system is NRF24L01 date transmission.We can design the wireless keyboard or wireless mouse by ourselves with this transmission function.
1.When the key in the sending part is pressed by someone, the 1602LCD will display the value of the key.
2.The value of the key will stay on the 1602LCD until other key is pressed. The 1602LCD will refresh and display the value of the new key.
