Playing Simon On A Hacked Farm Toy

About My kids have a plastic farm toy. It neighs, it baas, and frankly, it grates. But since I tricked it out with a microcontroller brain, at least it can play Simon. One of the marvels of parenthood is the sheer volume of noisy plastic junk that gets thrown your kids' way. It makes tremendous hacking fodder. For a while I had been watching to see if either of my daughters still expressed any interest in t ...

Pull-up Resistors explained

What is a Pull-up Resistor Let’s say you have an MCU with one pin configured as an input. If there is nothing connected to the pin and your program reads the state of the pin, will it be high (pulled to VCC) or low (pulled to ground)? It is difficult to tell. This phenomena is referred to as floating. To prevent this unknown state, a pull-up or pull-down resistor will ensure that the pin is in either a high ...

Will the SMD resistors marking become a history?

Everything implies, that the situation with marking of chip resistors (0603/0805/1206) will soon be similar to chip capacitors - i.e. no marking on the top of the component. The reason for this step is to reduce unnecessary chemical usages for environmental protections. Naturally, to identify the product resistance value, each single reel will be labeled with all relevant data as so far. Performance, featur ...
