Another illustration that demonstrate using rotary encoder. Rotary encoder is an electro mechanical device that convert the angular position or a motion of a shaft or axle to analog or digital code. Rotary encoder are usually used at the side
Wiring the Passive & Active Buzzer with Raspberry Pi
Another illustration that demonstrate how to use the buzzer both passive and active. The difference between an active and passive is. The active buzzer has a built in oscillating source that will make a sound when amplifying a power compare
Wiring The AX1838HS / VS1838 / NEC-IR 38K IR on Raspberry Pi
Another illustration demonstrating how IR Emission works on Raspberry Pi, for introduction how IR Emission works please refer to this link. IR (Infrared Receiver) is a device / component which receives IR signals and can independently receive IR rays and
Protecting your IO (Input Output) using Zener Diode
In a electronic system there are some inputs that controlled by the end user, these inputs are read by electronics and acted as an output. The inputs can come from a source, switches, buttons, sensors, relays, and communication device, etc.
