This home appliances control or home automation project also uses the same DTMF decoder circuit section with little modifications to control home and office electrical appliances. Just connect your cell phone headset (headphone) jack to the mobile phone and then mobile will control electrical appliances and electrical equipment through the DTMF key pad of your cell phone. Here for demonstrating, we are controlling an electrical bulb using this circuit project but you can extend this circuit to control many electrical devices with some modificat ....etc

The DC motors are applicable for effective speed control and high starting torque applications like traction, lift, etc. The Pulse Width Modulation twchnique of speed control can be used to obtain a a smooth speed variation without actually taxing in on the high starting torque of the motor. PWM technique also eliminate harmonics. Pulse-width Modulation is achieved with the help of a square wave whose duty cycle is varied to get a varying voltage output. As the average voltage output depends on the duty cycle of the square waveform, the actual ....etc
