So far with all my electronics circuits I have been using a DC wallwart so didn't have to think much about the current requirements of my circuits. Now I have a prototype that I would like to run ...
I'm in the process of designing a controller PCB for a 10x10 white LED matrix clock (inspired by the tutorial here). It's based off an ATmega328 AVR IC and Maxim DS3234 SPI RTC. However, I'm stuck: I ...
I have a problem with a relatively simple board which consists of an ENC28J60 Ethernet controller and an ATmega168. The circuit around the ENC28J60 is straight out of the datasheet and I have the ...
I'm building a serial servo controller to learn about electronics and assembly language as part of my hexapod robot project. Quite early on I decided that I needed more I/O channels than my ATTiny2313 ...
