The objective of this project is to illustrate a technique of implementing adaptive brightness control to seven segment LED displays. It consists of a closed loop system that continuously assesses ambient light condition using an inexpensive light-dependent resistor (LDR) and uses that information to adjust the brightness of the display. For the proof of concept, …
Temperature sensors are used in a wide range of electronic devices, including digital thermometers, home thermostats, ovens, and refrigerators. Figure 1 shows two devices with temperature sensors. Figure 1. Devices with temperature sensors. The temperature sensor provided in your kit is a precision analog sensor, whose voltage output is linearly proportional to the temperature. Configured …

Temperature and relative humidity are two very important ambient parameters that are directly related to human comfort. Sometimes, you may be able to bear higher temperatures, if there is a lower relative humidity, such as in hot and dry desert-like environment. However, being in a humid place with not very high temperature may make you …
In this post we will discuss about Green house intelligent control system: With the people’s living standards increasing, modern, a large number of agricultural production, such as vegetable using greenhouse to cultivate. The temperature and humidity monitoring are two key factors which used to control the growth of crops, due to different growth of greenhouse crops need …

When we are choosing PIC microcontrollers for projects on electronics or electrical, there are many options for us. Ranging from eight bit to Thirty two bits, diverse micro-controllers are accessible to go well with projects and products of different complications and cost restraints. But if we talk about student projects, it may be either major …
Design Goals DIY Friendly – Something that the Make audience could easily build Improve the reference design – Better measurement resolution, better timing, lower power, non-stop logging Minimal parts count – Lower cost and shorter build time Powered by a single 1.5 volt cell (AA, AAA, N or similar) and optional supplementary solar power Parts …

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 …

EEPROM is useful for storing long term data such as data logger information and this PIC microcontroller EEPROM project saves the temperature from an LM35DZ IC to the PIC’s internal long term data storage area. The project follows on from the last project using the virtually the same hardware. It stores temperature readings internally at …
