Temperature Controlled Fan Circuit for Audio Amplifiers
Amplifiers make heat when working. Too much of heat make it work bad and can die soon. This Temperature Controlled Fan Circuit for Audio Amplifiers keep amplifier cool. Fan starts only when amplifier is hot. If volume is low and less heat then fan stays OFF and saves power. The circuit is made with LM311 […]
Adjustable Thermostat Circuit using IC LM56
Electronic adjustable thermostat control temperature and it is used in heating or cooling system. This Adjustable Thermostat Circuit using IC LM56 is a low power chip which switches temperature in two ways. It controls outside transistor for output load. IC LM56 give reliable, precise temperature control. It is good for many uses like check temperature […]
DIY Temperature-Controlled Fan Circuit with Arduino
Modern devices and homes need good temperature control and this circuit help gadgets live long and make place comfortable. One example is fan with temperature control, fan change speed by room temperature and this keep temperature okay, save power and with less noise. Furthermore, the LM35 sensor measures the temperature and when the temperature becomes […]
Arduino Temperature Controller Circuit using DC Fan
This article show how to make Arduino Temperature Controller Circuit using DC Fan Arduino UNO, LCD, transistor, DHT11 sensor and with few resistors.
