Controlling AC and blinds with Raspberry Pi

If anything can be automated then it should be. Chris has an AC which has to be turned ON and OFF with remote. Also he finds annoying task to roll the blinds by tugging a chord. So he found a better solution to get rid of those periodic tasks. Luckily AC and blinds are close to each other, so he put a Raspberry Pi which is connected wirelessly to network. In order to control blinds, he used a stepper motor attached to roller shaft. Motor is driven by using easystepper motor driver. Since Air Conditioner is controller with remote. He attached IR diode and IR receiver to Raspberry Pi. Receiver is used to record IR signal from original remote in raw format. Then signal is transmitter through IR diode when… Continue reading
