PIC16F877A (with LCD) not working

I have designed a PIC18F877A micro controller project to read temperature from an LM35 using ADC, display it on an LCD and transmit it to a serial port. When the program starts, sometimes it shows a startup message - sometimes it doesn't display anything. Also, the serial port connection is not working. Can anyone help - am I missing something? Are there any ground connections missing? My code: #include #de ...

Arduino powered temperature sensing RGB LED nightlight using PICaxe

About a year ago I started on a project to make a temperature controlled nightlight. I was inspired by seeing these lovely LED lamps styled as mushrooms growing out of pieces of wood. Those mushrooms were made out of glass, which was somewhat beyond my skills. However I then saw some had used translucent sculpey to make mushroom nightlights on instructables. So with that discovery it seemed like it would be ...

DHT22 (AM2302) Digital Humidity and Temperature Sensor Proteus Simulation

Like the DHT11, the DHT22 is a digital humidity and temperature sensor which has more benefits than DHT11 like: High precision and range. If we want to understand this topic we have to read the DHT22 datasheet and see how this device works and its characteristics. Note that the DHT22 is available only on Proteus version 8.1 or higher, version 8.0 or later will not work therefore you have to update your vers ...

Temperature controlled fan using PIC 16F877A

You might have come across several applications where we need to control a specific device based on analog parameter. This Embedded system works in a similar concept where we are about to control the speed of a DC motor using based on the external temperature. The rise in temperature will result in increase in speed of the motor and vice versa. These type of Temperature controlled fan systems can generally ...

A Beginner’s data logger project using PIC12F683 microcontroller

It is a very simple data logger project based on PIC12F683 microcontroller. The microcontroller reads temperature values from a temperature sensor on a regular interval basis and stores them into its internal EEPROM memory. The recorded temperatures can be later transferred to a PC through serial interface. I originally published this project on electronics-lab.com last summer. I thought this could be a ver ...
