The Serial Peripheral Interface (SPI) is a high speed, synchronous, serial communication standard. This communication protocol is basically a Master – Slave implementation where the master device controls the clock based on which the slave devices operate. The master communicates with a slave or a number of slaves in a system through the SPI bus. …

Led indicators for on off status 5. Can be Rf controlled 6. Can be serially controlled 7. All code Flow charts …
Powersupply and CRT deflection and microcontroller test circuit. I was lucky to purcase two used but working DG7 tubes and a transformator cheap, one from Mullard and one from Phillips. Other CRT Cathode Ray Tube types can be used, you can even rip one from an old and maybe dead oscilloscope, then you also get …
You can add this circuit to all sorts of projects that require on-off control. Our design allows up to 4 touch sensors using a PIC12F629. The output of each touch sensor is active LOW and this can be connected to an additional circuit to control a LED, motor or relay etc. The photo of the …
What This Is This project is for a small electronic unit that allows the user to sense the presence and relative signal strength of wireless hotspots. It can be worn as a pendant or carried in a pocket. It is “always on” and communicates the presence and signal strength of an in-range hotspot by way …

Control up to 8 devices by this easy constructable remote control. It can work as a radio or infrared remote control, depending on the components. Each device output can be configured to be momentary (turned on while you press the button) or latched. Latched outputs can be toggled on/off by one button per channel, or …
Which types of PIC microcontrollers and EPROM’s are supported? You can use this PIC-Burner for PIC12C50x, PIC12F62x, PIC16FFxx, PIC16F62x and EEPROM 24Cxx. This PIC-Programmer was tested with PIC12C508 (A), PIC12C509 (A), PIC12F629, PIC12F675, PIC16F84A, PIC16F627, and PIC16F628. The PIC-programmer is easy to build and compact. 3 LEDs indicates the state of the burning-process. Red: burning, …

Small LED dot matrix development board I was very busy for the past two months so this blog just didn’t move. As you may know, the LED dot matrix display is my favorite device. I have designed a small development board for testing my led dot matrix related programs. The PCB is single sided so …
Here you can find out how to drive an led matrix with 64 LEDs (8 rows by 8 columns – 8×8 display) or less e.g. 35 LEDs (7 rows by 5 columns – 5×7 dot matrix). It uses persistence of vision to let you drive the 64 led matrix with only 10 microcontroller outputs! Normally you …
