These modules come in different shapes and colours and can be purchased from the internet for 3 dollars only. They are therefore cheap enough to enable many Internet of Things applications like monitoring your home temperature and activity all year round (if you ever need to do that). And at this price, you’re actually better […]

Ultrasonic distance measurement, detection circuit pic16f876 microcontroller and ad605 (Dual Low Noise Variable Gain Amplifier singlesupply) integrated circuit diagrams used are C and asm software also Resimlerdede oscilloscope’s measurement. 40kHz ultra sonic transducers used as sensors. I2C Sonar Ultrasonic Range Finder In many embedded systems design, it becomes necessary to have the capability of discerning […]

This wireless project is a power transmission system, it works on the principle of magnetic induction. This Wireless Charging system works as the digital switched mode power supply with the transformer, which is separated into two parts: The transformer primary coil is on the transmitter, working as the transmitter coil, and the transformer secondary coil […]

Arduino needs no introduction; it is an easy-to-use yet powerful open source embedded system development platform that has gained huge amount of popularity in past few years, specially among hobbyists. The standard hardware consists of an 8-bit Atmel AVR processor with on-board headers providing access to its I/O pins. The processor is pre-programmed with a […]

CAM204 The CAM204 is a single-chip non-contact position sensor IC for resonant inductive position sensing. Features Resonant inductive position sensing engine Fully ratiometric measurements SPI communications (slave device) User IOs for position triggers and sample indicators Measures up to 4 sensors Can drive external DAC for up to 4 analog outputs Internal software upgradable over […]

Description This project is a Microchip PIC microcontroller with an RS232 serial interface on one side and an Infra-Red receive and transmit interface on the other. Important – All mention of RS232 on this page actually refers to RS232 waveforms operating at 5V TTL levels not +/-12V levels which would destroy the PIC device. An […]

Description Recently I got a new motorbike and on my second trip out, with only 50 miles on the clock the rectifier/regulator unit failed.  The battery on a bike is pretty small and with the head light permanently on and all the ECU, ignition and fuel injection stuff it didn’t take long to run the […]

This project is a miniature Audio CRO. For those not familiar with the abbreviation “CRO,” it means “Cathode Ray Oscilloscope” and this is sometimes shortened to “SCOPE or O-Scope.” A “CRO” is a piece of test equipment with a screen. It produces a visual indication of a waveform, via a probe, when the waveform is […]

Short Introduction: I have been following the Battle of the DreamBoards Championship with interest and I enjoyed the variation of functionality features put together in each of the dreamboards.  I especially had my attention attracted by the combination of audio inputs and outputs, analog to digital and digital to analog converters, and the microcontroller digital […]
