Smoot Digital Servo with DRV 8833. ************** =9= *************** For example DIY construction of two digital servos using mini N20 or 050 motors and potensiometers. DRV 8833 is a dual H-Bridge, which is why there are two software inplementations, Channel A en Channel B. Now it has a "DEAD" Band Gap and Uses "RAW-ANALOG-READ " !

Node to drive a MC14511B 7 Segment IC.

Simple asynchronous web interface with four buttons

The node is designed to work with the miniature HC-SR505 motion sensor. It allows detecting movement of people and animals within the sensor's range. HC-SR505 Technical Specifications Supply Voltage: 5V - 20V (optimal 5V) Current Consumption: 50 μA Detection Angle: 100° Detection Range: 3 meters Frequency: 20 Hz Node Pins Input Pins: IN - digital pin number of Arduino connected to the sensor's OUT pin UPD - update pin (triggers reading from the sensor) Output Pin: OUT - boolean value: true - motion detected false - no motion detected
