After a long semester with nearly no time to tinker with the Raspberry Pi, I am back, this time experimenting with the Passive Infra-Red (PIR) Sensor to build a motion detector alarm. First let me explain briefly the working principle of the PIR sensor. All objects with a temperature above absolute zero (0° K or -273° C) […]
Electronics are very fun to play with but adding computer science to it makes it more fun. Following the previous post of using a breadboard, we are now going to control program LEDs to flow by a certain pattern using the C programming language on the Raspberry Pi. The Raspberry Pi consists of General Purpose Input/Output […]
As mentioned in my earlier post, I bought a Raspberry Pi 3. I also bought an electronic starter kit to use with it. The kit came with a breadboard, a board used for prototyping circuits. You might find it funny but I did not know how to use a breadboard. Breadboards come in different sizes and they […]
