So [Todd] has set out to build an Arduino frequency counter for a Kenwood TS-520S HF ham radio. This post (and the video found after the break) doesn’t cover the entire project. It’s rather ...

Geiger counter, it's a word that most people have heard about. I'm sure everyone has seen at least one piece of media featuring the clicking box with a little dial that only tells you when you're ...

although the last pulse might be truncated. Within this, TCCR1A and B are the timer control register. The least-significant three bits of B an turn off the timer if that are set to 000. In the mode ...

Literally, ATtiny85 is a scaled-down version of the Atmega microcontroller on Arduino boards with just a few ... We get two 8-bit timer/counters, one high-speed, with four pulse-width modulation (PWM) ...

It’s something [FrankBuss] has approached with an Arduino-based counter that offloads the timing question to a host PC, and thus claims atomic accuracy due to its clock being tied to a master ...

Electronics designer Patrick Thomas Mitchell has returned once again to Kickstarter to launch his new Raspberry Pi and Arduino programmable timer aptly named the Ninja Counter. The programmable ...
