Automatic Speed Controller for fans and Coolers: During summer nights, temperature is initially quite high. As time passes, temperature starts dropping. Also, after a person falls asleep, metabolic rate of one’s body decreases. Thus, initially fan/cooler needs to be run at full speed. As time passes, one has to get up again and again to adjust speed of fan or .… (added 10/05)

AVR microController makes improved motor Controller: 10/17/02 EDN Design Ideas / (added 1/05) The circuit in Figure 1 provides a novel method of reading pulse train using an Atmel (www.atmel.com) AVR processor, from a typical radio-controlled receiver, and to determine velocity of a motor. To capture pulse train from a typical receiver, you need an external interrupt that triggers based on a rising and a falling edge....
