Thermometer Circuit is like a small detective for heat, as it has got special sensor which smells temperature and then show on the screen like digital thermometer. Also, these circuits come in many shape and size for the use in different way to feel temperature, but no matter which one all of them will indicate […]
Simple TV Remote Tester Circuit
Simple TV Remote Tester Circuit is small tool like a doctor for ones remote, as it uses one infrared sensor like eye for light which we cannot see and to check if remote give signal when one presses the button. If signal arrives small light turns ON or buzzer make beep sound which means remote […]
Simple Heat Sensor Circuit using a Single Transistor
To begin with, this Simple Heat Sensor Circuit using a Single Transistor and one special resistor like thermometer. When it get hot this resistor changes to how it work because of which the transistor sees this change; also the transistor work like a door and if temperature changes it opens or closes for electric. So […]
Squelch Circuit
Squelch circuits are like the radio peace assistant!; and this small smart circuit stops radio sound when no strong signal connects. So no more hearing of bad noises but only when signal is strong one can hear good sound or video; also the best thing about squelch is its very easy and works with many […]
Touch Controlled Potentiometer Circuit
This Touch Controlled Potentiometer Circuit one just need to tap it and it will start to work; also there is no need to turn knob or move the slider it just touches the sensor and it changes the resistance or voltage. Furthermore, it uses capacitive sensing which means that when one contacts it, the body […]
