Temperature Controlled LED Circuit
This small Temperature Controlled LED Circuit can feel the heat! When we place near warm thing, it sense temperature and LED glow and it work very simple using one diode and one transistor only. No microcontroller, no sensor IC, just few parts and also we can build it easy at home and see how heat […]
Automatic Light Control Circuit using LDR and LM3909 IC
This Automatic Light Control Circuit using LDR and LM3909 IC is small and smart light sensor circuit which can feel light and dark like magic; also it uses few circuit parts like LDR, LM3909 IC, capacitor and an LED. When dark come, LED turns ON and when light come, LED goes OFF, which is perfect […]
LDR Light Sensor Circuit using BC547
To begin with, this LDR Light Sensor Circuit using BC547 works by itself; when it is dark the LED turns ON and when light comes then LED turns OFF. LDR feels the light and controls the LED and there is no need to press any switch. Additionally, this simple and very low-cost circuit works well […]
Chirping Sound Buzzer Circuit
This simple circuit makes a normal buzzer produce a chirping or tweeting sound; it uses a 9 V battery, two push buttons, one capacitor, and a buzzer, also the circuit also does not need a microcontroller or IC. Also, it works on charging and discharging of capacitor and this Chirping Sound Buzzer Circuit is good […]
Make Sound with Arduino using Buzzer Circuit
This project shows how to Make Sound with Arduino using Buzzer Circuit; also buzzer makes sound when we send signal from Arduino pin. Here, we can use it for alarms, alerts, or simple tones; moreover, we use two versions here: one with individual components and another with a buzzer module. Arduino Code: Code Explanation: Parts […]
