Smart Washroom: Experience Hands-Free Lighting with IR Sensors

Sensor – Transducer – Detector Projects / By

This Arduino Uno and IR sensor-based system automatically controls the lighting in a bathroom connected to AC mains power. The IR sensors detect when a person enters or exits the room. Upon detection of entry, the light bulb or tube light is immediately switched on. When the sensors no longer detect a presence, the lighting […]

Physical Computing and DC Motor Control

Arduino Motor Project Ideas / By

Managing a DC motor through an Arduino is a straightforward task. Beyond employing a basic electric switch, there are diverse approaches to engage with a motor. Moreover, the conventional electromechanical relay can be readily substituted with a carefully chosen transistor, enabling software-based speed control. This chapter will investigate multiple strategies for DC motor control, encompassing

Electronics News Updates / By

ROHM Semiconductor Ultra Compact MOSFETs & Bipolar Transistors have the smallest transistor package on the market which is optimized for thin, compact portable devices. The VML0806 case type measures just 0.8mm×0.6mm, with a height of only 0.36mm. As portable devices, such as smartphones and digital cameras get smaller and more sophisticated, thinner, more compact components

I was supporting a group of student on their graduation project. One of the difficulties they faced was on controlling an A/C unit with Arduino microcontroller. The first experiment we tried to work it out was by record the A/C remote control beam signal for each needed button by using the IRrecvDump code with IRremote

This week, we’ll finally be using the Arduino to control some motors! First up, we’ll control a standard DC motor running off a 9V battery with the help of an NPN transistor and a PWM (Pulse Width Modulated) signal from the Arduino.
