Technical Specifications I want to make my home theater wireless. My home theater model is Sony SRS-D9 2.1 channel. […]
Make this DC CDI Circuit for Motorcycles
The circuit presented here is for a DC-CDI which are used in motorcycles. A DC-CDI is the one in which the high voltage (200-400VDC) is converted from 12V supply voltage. Researched and Submitted by: Abu-Hafss Studying the circuit, we see that it has two parts i.e. the CDI unit, enclosed in the pink box and […]
Microwave Sensor or a Doppler Sensor Circuit
In this article we study the microwave sensor IC KMY 24 and try to understand its main features and its pinout implementation details. How Doppler Sensor KMY24 Works The KMY24 microwave sensor module is designed and built on the concept of Doppler effect. When correctly configured it radiates a low power microwave signal of around […]
Blinking 3 LEDs (R,G,B) Sequentially Using Arduino Circuit
In this post I have explained how to run or blink three LEDs in sequence using Arduino. The post was written and submitted by: Jack Franko PROGRAM/* make RGB LEDs to blink in series one by one at intervalof 1000MS */ int R = 12;int G = 11;int B = 10;void setup(){ pinMode(R,OUTPUT); pinMode(G,OUTPUT); pinMode(B,OUTPUT);}void […]
