I have been given a task to build an attendance system for staff. The requirements are quite straight-forward. It needs to be standalone (without computer), fingerprint is preferred, record real time and the record should be in SD card. 1.0
The new cube servo, G15 from Cytron Technologies is amazing actuator. Beside the angle/position control feature (like a standard RC servo), it also offer continuous rotation :)[youtube]https://www.youtube.com/watch?v=yGuZDgbj4xI[/youtube] We are going to show a simple mobile robot construction using G15 as
In this tutorial, you will learn how to read and write files in a Micro-SD card using a microcontroller. Do not worry as you will be using Microchip’s Memory Disk Drive File System (MDDFS) libraries to help you to do all of these immediately. One thing about the library is, it requires a lot of microcontroller’s program space. The dsPIC30F4013 will be used in this project since it has 48KB of program memory.
Introduction GSM modem is a specialized type of modem which the wireless network is likely similar to our hand phone device. Now it can directly connect to our computer via COM port (serial port) and using the HyperTerminal (UART), we
Ever heard of an embedded electronic project called LED cube? Actually, this project had been done by many embedded electronic hobbyists due to its interesting display effects by lighting up LED Cube in certain patterns. The LED Cube lighting patterns can be controlled by microcontroller based on the program loaded into it. In this tutorial, user will be guided to build up a 8x8x8 LED Cube in step by step.
Introduction LSA08 is an Advance Line Following Sensor bar with build up with 8 pair of super bright green LED as the sensor’s transmitter. LSA08 is able to operate at various color surfaces with distinct brightness. The LSA08 has several
