I got my PC boards from OSH Park. The top boards are just some SOT23 breakouts to make breadboarding easier. Soldering wire legs onto SOT23s is a little difficult, and they don't hold up well to plugging and unplugging.
The bottom boards are my PIC10F322 general purpose board. OSH Park shorted me...
I was recently looking at Microchip's PIC10F322 microcontroller and thought it was a very capable little MCU for its price (and size). It has some really interesting peripherals onboard, like the Configurable Logic Cell (CLC), the Numerically Controlled Oscillator (NCO) Module and the Complementary...
In a recent Ebay China toy order I grabbed four HY-SRF05 ultrasonic rangefinder sensors to play with. Can't beat the price at $1.89 USD each with free shipping. They'd be dirt cheap at twice that price.
Here I'm controlling the SRF05 with a PIC18F2680 and displaying the results on my "Predko" 2-wi...
Jason at AtomSoft sent me a couple Nokia 7110 LCDs. Thanks Jason! They're nice cheap little 96x65 monochrome graphic LCD's if you can find them. In this project I build a breadboard connector for the display and write some PIC 18LF1330 code and some 18F2550 code to drive the display
I made a con...
To decode Sony SIRC codes output by my Harmony 880 remote control, I connected a Panasonic PNA4602M infrared sensor to P0.4 (CAP0.1). It's a 38kHz type sensor, so it works great with standard remote controls. Rather than work blind, I connected a 16x2 character LCD in 4-bit mode with busy flag check...
