This project shows how to decode IR remote controls which uses Philips RC5 protocol with microchip PIC16F84A microcontroller. You can find details about RC5 on Wikipedia Related topics: Philips RC5 & LG TV Remote Control Decoder IR Remote Control Based On PIC Microcontroller The RC5 protocols can be divided into 4 parts: 1-start bit, 2-Toggle […]

Why did I build a power bank? Why would anyone even try to build a power bank – i.e. an external battery for charging mobile devices – these days? These things are commodity, it’s impossible to compete. Right? Well, that is until you find out that the type of power bank for your application, namely

Back then, only several individuals and companies are very concerned about online safety and privacy. Thus, they consider installing and using a virtual private network (VPN) vital to protect their sensitive data and online activity from cyber-criminals. But as the years passed, online safety has become a priority not just to big companies, government offices,

This is the first post of a 3-part series about reading out an SMA solar inverter over Bluetooth and displaying some readings every few seconds. Long-time readers may remember the Solar at last weblog post from several years ago and the SMA Relay, based on a JeeNode v6. The Bluetooth readout code was derived from Stuart Pittaway’s Nanode SMA

So far, we’ve talked about the basics of SPI communication and UART communication, so now let’s go into the final protocol of this series, the Inter-Integrated Circuit, or I2C. You’ll probably find yourself using I2C if you ever build projects that use OLED displays, barometric pressure sensors, or gyroscope/accelerometer modules. I2C combines the best features of SPI and UARTs. With

When you connect a microcontroller to a sensor, display, or other module, do you ever think about how the two devices talk to each other? What exactly are they saying? How are they able to understand each other? Communication between electronics is like communication between humans. Both sides need to speak the same language. In electronics, these languages are called communication

overview There are three PIC source versions: PB12 is for 12-bit slave devices without interrupt PBUS is for slave devices with an interrupt, software UART implementation PB628 is for slave devices with an intterupt and a free hardware UART PBUS assigns a unique device ID in the range 1-f for every controller on the bus.

The mikroC PRO for PIC provides a library (driver) for working with the CAN module. The CAN is a very robust protocol that has error detection and signalization, self–checking and fault confinement. Faulty CAN data and remote frames are re-transmitted automatically, similar to the Ethernet. Data transfer rates depends on the distance. For example, 1

Philips invented the RC5 protocol for controlling electronic equipment such as CD players, VCR’s and audio amplifiers way back in the 1980’s. The RC5 standard has been adopted and used with great success ever since, which means it is probably the most common IR remote control format in your home today. We have recently been
