XBee Based Temperature and Gas Monitoring System Using Pic Microcontroller
DsPIC33F microcontroller based pure sine wave inverter
In this post we will brielfy discuss DsPIC33F microcontroller based pure sine wave inverter. The majority of the technological devices used with the development of the technology use the network voltage (220V-50Hz). Conversion must be done to obtain the mains voltage from the DC storage voltage sources. This conversion can be done by inverter. In […]
MPPT Based Charge Controller Using Pic Microcontroller
In this post we will briefly discuss about MPPT Based Charge Controller Using Pic Microcontroller. Photovoltaic is one of the renewable energy resources that recently has become broader in nowadays technology. The electricity generations of photovoltaic (PV) panels are strongly related with insolation and temperature. The insolation and temperature are not stable, since the electricity […]
Heart beat pulse sensor interfacing with pic microcontroller
Heart Beat rate is most important parameter in monitoring any person’s health. In the modern era of wearable devices, there are lot of devices which can measure heartbeat, blood pressure, footsteps, calories burnt and lot of other things. These devices has pulse sensor inside them to sense the pulse rate. Today, we will also use […]
How to display 5×8 and 5×10 size font characters on 16×2 lcd with 8-bit microcontrollers
Character lcds can display character of font size 5×8 and 5×10. In 5xn, 5 represents number of coulombs and N represents number of rows. Character lcd’s especially which are controlled by Hitachi HD44780 controller can display 5×8 and 5×10 size font character. Some lcd’s can only display character in 5×8 font. In this project i […]
Interfacing LM35 temperature sensor with PIC18F4550 microcontroller
Interfacing PIC18F4550 with LM35 This small topic shows the circuit diagram and CCS C code of the interfacing of LM35 temperature sensor with PIC18F4550 microcontroller. The LM35 temperature sensor is three pin device (VCC, OUT and GND) with an output voltage linearly related to Centigrade temperature. Since the LM35 output varies with dependent to the […]
Wave player using PIC18F4550 microcontroller
Making an audio player (.wav files) using PIC microcontroller is not complicated especially when the MCU has a PWM module. This topic shows how to build an audio player using PIC18F4550 microcontroller where the the file is stored in an SD card with FAT16 or FAT32 file system. In this project I used a wave […]
Remote controlled USB mouse using PIC18F4550
Building a USB mouse using PIC18F4550 microcontroller and CCS C compiler is easy as shown in the link below: USB Mouse using PIC18F4550 microcontroller Also, it is not hard to add an infrared remote control to the previous USB project. This post shows how did I build a simple IR remote controlled USB mouse using […]
MMC/SD Card raw data read with PIC16F887 microcontroller
Interfacing MMC/SD card with PIC16F887 This small example shows how to read SD card raw data (bytes, sectors …). SD card raw data means that there is no use of system files like FAT16 or FAT32. Serial monitor is used to display the data after reading it and here the UART protocol is used. the […]
