A basic clock that self-corrects when timeslipping is detected. Also includes an alarm system that triggers a siren (after countdown) when motion is detected. User enables/disables alarm via code. no ...

IR Sensor Pinout. The IR sensor has a 3-pin connector that interfaces it to the outside world. The connections are as follows: VCC is the power supply pin for the IR sensor which we connect to the 5V ...

What do you need to build an Arduino Speed Sensor. Building an Arduino speed detector using IR technology to measure the speed of a moving object is much more cost-effective, and it is also very ...

Today I am sharing the Proteus simulation of my project, in which I have shown the working of three sensors with a single Arduino. These include a PIR sensor (digital), flame-detecting sensor (digital ...

Fig. 1: Author’s prototype Fig. 2: Block diagram of motion sensor alarm Circuit and working. The circuit diagram of the motion sensor alarm is shown in Fig. 3. It consists of a PIR motion sensor (MS1) ...

Sometimes, the best Arduino projects are the most ridiculous. Case in point, this motion-detecting squirt gun.The idea is simple: when it detects motion, the spray gun activates.
