Optoisolator220v
Gonzalez Ferreyra Oct 25,2017
### DESCRIPTIONUltra simple and easy way to detect mains presence and report to microcontroller of your choice.Optoisolated with very popular PC817 from Sharp. and output is pulled from uc power source. ### TECHNICAL DETAILS / COMPONENTSThe .01uf cap will act as a voltage reducer and diode in inverse will discard all negative cycles. 100R resistor has some power dissipation so should be of 1/4W at least. Has been tested for several months and works perfectly well with mains 220v . ...

SonicDisc - A 360° ultrasonic scanner
Dimitrios Platis Aug 24,2017
SonicDiscA 360° ultrasonic scanner that talks over I2C using an Atmega328P and 8 HC-SR04 ultrasonic sensors.OverviewSonicDisc is a sensor that allows you to sense your surroundings. It utilizes 8 ultrasound sensors (HC-SR04) placed at 45° angle from each other, that can measure distances from practically every direction. It can be used in hobby-grade automotive applications, e.g. autonomous driving, obstacle detection etc or wherever quickly determining surrounding distances is relevant.The sens...

Rotation Sensor Module
PCBWay Team Aug 17,2017
IntroductionSENZ001 Rotation Sensor is arduino compatible multi-ring rotation analog sensor. It is based on multi-turn precision potentiometer. It can rotate upto 10 laps. If the sensor input 5V voltage power, then the 5000mV will be divided into 3600 portions(10 laps). When you adjust the rotation of the 3 degrees and then the voltage will have 2mV change. So you can accurately achieve the effect of voltage with small changes. And it is easy to be connected to Arduino.S...
