Control accurate incremental voltage steps with a rotary encoder

Experimenting with an HF oscillator, I needed to control the varactor diode voltage in precise increments over a 2V-10V range. A buffered potentiometer was the obvious choice, and connecting two pots in series to give coarse/fine control (or using a multiturn pot) would offer improved control over the varactor voltage. However, this approach still didn’t […]

Control Loop Challenges of Wireless Systems

Electronics News Updates / Ibrar Ayyub

Though embedded modules can be used be used with Wi-Fi, the aim of recent protocols is providing wireless networks with more focused support for control loops. For tight control loops, devices supporting the IEEE802.15.4 ZigBee standard can be used in supporting the recent protocols. Below is a Microchip’s MRF24WB Wi-Fi module. For sharing a common

Control servo motors with potentiometers and Arduino

Electronics News Updates / Ibrar Ayyub

I needed to be able to control 3 different servo motors by altering the position of 3 potentiometers. There are lots of people out there doing things like this, but I couldn’t find an exact match for everything I needed, so I decided to post up this instructable to bring everything I learned together in

Freeze 75 – and you have a temperature under control

Electronics News Updates / Ibrar Ayyub

A device operates OK until it reaches stable operating temperature … a typical situation in praxis usually caused by a faulty component or faulty (cold) joint. Localization of such a fault is easy only if we can cool down (locally) a given component or a given joint. It´s often possible to suppose a source of

More awesome DoorBell control

Electronics News Updates / Ibrar Ayyub

My first DoorBell Mote prototype was working nicely and it allowed monitoring the door bell (while also triggering it remotely – toddlers love it). But I wanted more. On weekends the family likes to get a well deserved nap during the day and often those pesky solicitors ring the bell and wake everyone up. So naturally the doorbell has to be

Auto Intensity Control of Street Lights

Sensor - Transducer - Detector Projects / Ibrar Ayyub

treet lights are controlled manually in olden days. These days automation of street lights has emerged. But one can observe that there is no need of high intensity in peak hours i.e. when there is no traffic and even in early mornings. By reducing the intensity in these times, energy can be saved to some

Simple Single Motor Control using AVR ATmega16

Motor Projects / Ibrar Ayyub

Microcontrollers are good when it comes to brain, but to do anything in real world they need muscles too ! Their muscles are electromechanical actuators like motors. Their are several types of motor available to do various type of motion. The simplest of them are DC motors. They can generate rotary motion and when wheels

Radio Control Car using Mega32

Car Projects / Ibrar Ayyub

Introduction: We like car and we like to build our own Atmel Mega32 MCU based radio-controlled NSX. We set three goals in the initial project proposal and they are as the following: (1) Build a RC NSX with the same performance as the original car. (2) Add extra features such as headlights and brake lights.

An Introduction to Brushless DC Motor Control

Electronics News Updates / Ibrar Ayyub

The brushless DC (BLDC) motor is becoming increasingly popular in sectors such as automotive (particularly electric vehicles (EV)), HVAC, white goods and industrial because it does away with the mechanical commutator used in traditional motors, replacing it with an electronic device that improves the reliability and durability of the unit. Another advantage of a BLDC
