Simple DC Motor Speed Control Circuit Diagram using IC 555 ... The DC MOTOR SPEED CONTROL circuit is primarily a 555 IC based PWM (Pulse Width Modulation) circuit developed to get variable voltage over constant voltage. The method of PWM is explained here. Consider a simple circuit as shown in figure below. If the button is pressed if the figure, then the motor will start rotating and it will be in motion until the button is pressed. The Transistor Amplifier Talking Electronics Fig 1. NPN Transistor: Fig 1 shows an NPN transistor with the legs covering the symbol showing the name for each lead. The leads are BASE, COLLECTOR and EMITTER. The transistor shown in the photo has a metal case with a tiny tag next to the emitter lead. Automatic Washroom Light Switch Electronics Hub Introduction. In this project, I will show you how to design and build a simple Automatic Washroom Light Switch Circuit, which will automatically turn on the when you enter the washroom and turns it off when you leave. 101 200 Transistor Circuits Talking Electronics Kit for Transistor Circuits $15.00 A kit of components to make many of the circuits described in this eBook is available for $15.00 plus $7.00 post.

This is the most important piece of equipment for testing and measuring digital equipment. It is usually used in fault finding and testing but can also assist in design work and to find out how digital equipment works. LED Fade In Fade Out Dimmer PCB Heaven Some time ago, i made an LED fade out dimmer for my Men Of War game console.The circuit was ridiculously easy, using only one transistor and a couple more passive components. Now, i tried to make a similar circuit, but with a Fade In Fade Out cycle (the previous had only fade out). The Beaglebone for Embedded Linux Development | derekmolloy.ie Introduction. I have developed a full series of videos on the BeagleBone — an embedded Linux single board computer (SBC). The BeagleBone White retails for about €85 and all of the first set of videos are based on this board. ARM Cortex M The ARM Cortex M is a group of 32 bit RISC ARM processor cores licensed by Arm Holdings.They are intended for microcontroller use, and have been shipped in tens of billions of devices.
