Automatic Street Light Dimmer Using Motion Sensor

Automatic_Street_Light_Dimmer_Using_Motion_Sensor_circuit

“Save Energy For Future” one of the most common motto which we we’ve seen or heard throughout our life, Well, here we will be implementing it through this simple circuit. The power loss from street lights can be reduced to a large extent by implementing an automatic dimmer, which will reduce and increase the brightness automatically. This…

Build Arduino Based Home Security System Using PIR Motion Sensor

home_alarm_systems

PIR sensors are widely applied in wireless residential security systems, home alarms systems and many more security circuits as motion detector sensors. A typical PIR sensor detects the infrared red (IR) waves from human body and so it is also known as ‘human sensor’. It would be wonderful if we interface PIR sensor to Arduino…

Simple Transistor Tester Circuit Diagram Using 555 Timer IC

Simple Transistor Tester Circuit diagram using 555

Recently I received a comment from Mr. Simran, one of our reader regarding Home Security Alarm. He said he ran into some faults while setting up the circuit. I suggested that the problem is most probably due to troubles in transistor. After two days he replied back saying he has problem with transistor. Most of the electronics…
