RFID reader is device to read card and lock/unlock some kind of functions. General driver RFID is RC522 module. Microcontroler send information to alphanumerical display HD44780 and Bluetooth terminal HC-05.
The generator is based on LT6900 integrated circuit. In this situation, it is possible to build it easily and place it in small enclosure. Amplitude and frequency regulation is carried out on potentiometers. With the help of the switches, you can select the frequency control range and the power mode.
Precision regulated stabilized power supply has been constructed from modern integrated stabilizers. This device have fast impulse response, it is suitable for testing digital circuits. It will also facilitate work in the construction of low power systems, where precision and low noise levels are particularly important.
