Circuit HAMCOMM MODEM

The program only needs a simple “infinite gain” circuit to square off the input tones so that they can be read by the serial port. This is achieved using a 741 operational amplifier. The basic circuit of the unit is given below. The RS232 pins are given for a 9-pin serial port. A 25-pin port […]

How make a thermostat in the room – Thermistor

let us make a thermostat in the room, this circuit energizes the relay when the temperature rises above a specified level. The second series of energy in the relay when the temperature falls below a preset level. Both series are virtually identical. The only difference between them is the polarity of the transistor. Thermistor value […]
