This post would provide a working example of how to make a simple Current Meter (DCM) using 16bit PIC microcontroller and a series shunt resistance. We have very precise ammeter current measurement with a 10bit ADC and with a tolerance of ±10mA. You may download code and Proteus Simulation from the download section at the […]

The STS3x is Sensirion’s newest high-accuracy digital temperature sensor series. The STS3x temperature sensor utilizes the industry-proven CMOSens® technology and wins over users with its increased intelligence, reliability, and improved accuracy specifications. The functionality of Sensirion’s new STS3x temperature sensor includes enhanced signal processing, two distinctive and user-selectable I2C addresses, and communication speeds of up […]

Any hobbyist can charge a battery quickly, but can you do it without an explosion, excessive heating or major degradation in battery cycle life? Well many companies have managed fast charging techniques  that typically use specialized algorithms. These algorithms take into account the chemistry of the battery and some sort of non-standard charging rate curve. […]

In some of our projects, we may want to measure the distance of an object from a point. Ultrasonic Distance Sensors are the best sensor which provides stable, accurate, precise, non-contact distance measurements from 2cm to 4m. Ultrasonic Sensors can be used to measure distance between moving or stationary objects. Being very accurate and stable, these devices […]

PIC32 ICSP Programmer v1.0 is based on a simple PIC32MX270F256B microcontroller basic circuit. It connects to a PC via USB 2.0 port and therefore needs no external power supply. It may be used to program a PIC32 microcontroller on a circuit via ICSP interface or you may add a programming header. It basically works similar […]

The Project is based on LV8727E IC from ON Semiconductor. The LV8727 is a PWM current-controlled micro step bipolar stepping motor driver. This driver can provide eight ways of micro step resolution of 1/2, 1/8, 1/16, 1/32, 1/64, 1/128, 1/10, 1/20, and can drive simply by the step input. This Bipolar Driver works with supply […]

Microchip has included a new power building block in a microcontroller aimed at LED lighting. Called the PIC16(L)F1769, the family has the first PICs to offer two independent closed-loop channels. The firm has steadily been introducing power control peripheral blocks over the last three years – so-called ‘core independent peripherals (CIPs), including for example its […]

Usually We need embedded systems inside devices, particularly the so-called intelligent devices, to communicate with a command/control/administrative center. Typical such situations could be a remote security camera that can send you video clips when queried, an embedded system that can send status when checked through a web browser or a vending machine that is capable […]
