This should be useful when burning any bootloader using an Arduino. But it does make us wonder if there isn’t an alternative method that would let you draw the clock signal from the Arduino itself?

Making an Arduino shield can be simpler than you think. This time I designed one to program Attiny and Atmega microcontrollers, that way I don't have to use a breadboard and make the wiring to program ...

The Arduino IDE provides access to these through a function in tools called ‘Burn bootloader’ (available in the Tools menu). In proper Arduinos, this sets appropriate non-volatile flags and downloads ...

Security is something that’s far too often overlooked in embedded devices. One of the main risks is that if the device doesn’t verify the authenticity of incoming firmware updates. [Walter Schreppers] ...
