Onboard signal lights all the way

but also found in other systems where a proximity card is desired

servo motors you can position the motor shaft at a specific position (angle) using control signal

The pin can also be attached to a digital output on the MCU and turned on/off when samples are being taken

Solid State Relay Module (4 Channels- 5V) Button Onboard signal lights all theIntroduction : This module is capable of switching AC voltages between 100 and 240V at up to a 2A current. The module can be controlled from a 5V Solid state relays, have several advantages over mechanical relays such as It has a longer life, with a much higher turn on off speed and no noise. It also has better resistance to vibration and mechanical shock and better moisture proof performance. It can be switched by a much lower voltage and at a much
