Working with Flame Sensor - Fire Alarm System

One of the components in our starter's kit is a photodiode which detects light. When fire burns it emits a small amount of Infra-red light, this light will be received by the Photodiode (IR receiver). The photodiode in most starter's kit is a YG1006 sensor which is a high speed and high sensitive NPN silicon

Working With Servo Motor

Servo motors are a special type of motor that don’t spin around in a circle, but move to a specific position and stay there until you tell them to move again. Servos usually only rotate 180 degrees (one half of a circle). Servo motors are a special type of motor that don’t spin around in a circle, but
