In this session we will see how to interface 16×2 LCD to PIC18F4550 microcontroller which is of family PIC18F. You can get information of 16×2 LCD in the session How to Interface 16X2 LCD with 8051 Microcontroller Features of PIC18F4550: PIC18F4550 belongs to the PIC18F family; PIC18F4550 is an 8bit microcontroller and uses RISC architecture. PIC18F4550 […]

Novelda, with its XeThru technology based on UWB microwave sensing, offers medical grade monitoring of respiration that can be easily used in everyday lives and homes. With its wireless measurement principle, and non-contact capability, users are not bound by wearing on-body sensors or keeping them charged every day. The respiration module will detect body movement, […]

From the block diagram given above you can see that this project has four major parts. The Power Bank Finding a good power source for this project was a challenge, the power supply should have to be mobile, so that we cannot use power adapters. Also it had to be rechargeable so that it is […]

Lasers have been one of the essential technologies used in industries. It is realized that light outperforms radio in terms of speed and density. It has been used for communications whether in scanning barcodes, reading CD’s and DVD’s. This design is a simple data transmitter that uses a DIP switch to support the transmission of […]

GPS satellites and GPS Ground Segment need extremely accurate timing to allow GPS users to know their own position on the Earth. Rubidium and Cesium clock generators are extensively used and maintained to synchronize and generate the signals that our inexpensive navigator gets from the GPS satellites orbiting at 20000 Km. Many commercial systems use […]

This project describes an easy and inexpensive way of adding a digital thermometer and data logging feature to a PC. It involves a PIC microcontroller that gets the surrounding temperature information from the Microchip MCP9701 sensor, and sends it to a PC through an USB-UART interface. The USB port of the PC is also used […]

Description The TPS61093-Q1 is a 1.2-MHz, fixed-frequency boost converter designed for high integration and high reliability. The IC integrates a 20-V power switch, input/output isolation switch, and power diode. When the output current exceeds the overload limit, the isolation switch of the IC opens up to disconnect the output from the input. This disconnection protects […]

Many of you may have seen the Adafruit PCB ruler (also used by the awesome Voltera). The design was actually adapted from my own design back in University! To improve on the original idea, I have created a reference business card.   Here is a computer render of the design: PS. The dots on the […]

Telit and SiTime say they’ve made the the world’s smallest and lowest power GPS receiver with extended hibernation periods at 15µA while maintaining Snap Start to less than one second. The receiver uses Telit’s Jupiter SE880 and SiTime’s MEMS SiT15xx oscillators. SiTime’s devices claim to offer offer area savings of 85%, cut power by 50% […]

Few months ago Microchip introduced smallest, lowest-cost PIC32 microcontrollers – new PIC32”MX1” and PIC32”MX2” families. PIC32 MX1 and MX2 MCUs include up to 32 KB of Flash and 8 KB of SRAM, two I2S interfaces for audio processing, 10-bit 1 Msps ADC, an 8-bit Parallel Master Port and serial-communications peripherals. MX2 MCUs also have USB […]
