1hz is only available on some watches. The f5, f5s, f5x, 935, and Q5, but if you support a bunch of different watches, you can easily have it on some and not others. 1hz happens by way of a …

2018年11月29日 · I would like to set a pwm output on my UNO to run at a 1 Hz frequency and then, by analogWrite, set it at 10% or 90% dutycycle. Can that be done? If so, how do I do it? …

2018年9月24日 · Hello, i am learning how to use I2C, speccially with ds3231 for starting, there are a lot of libraries to make ds3231 work but i want to learn from scratch, i´ve been readiing some …

2011年5月24日 · I am thinking about making a no-microcontroller clock/timer/stopwatch (74 series ICs only + passive components, preferably). To make it as simple as possible I want to have a …

2021年9月8日 · One is to measure mains grid frequency using a optocoupler and an external interrupt. The second code is to create a PWM on pin 9 with a frequency of 1Hz. I am …

2020年8月21日 · Hi, I can find lots of "hits" for MAX PWM Frequency, but I want Sub-Hz values (0.1 - 0.5Hz). Using this commonly found technique: int PWM_FREQUENCY = 1; // this …

2012年7月27日 · Like said in the subject what would be the easiest way to make an adjustable square wave(50% duty cycle) that can be adjusted from 1hz(doesn't have to be that low but …

2013年1月5日 · Hello everyone! I have been trying to use the Arduino Uno to create square pulses at the following frequencies, 10Hz, 5Hz, 1Hz, .5Hz, and .12Hz using PWM. I’ve been …

2017年7月25日 · I want the ATTiny85 asleep as much as possible, only really awoken on the tick of 1 second (1Hz) or when a button is pressed. The issue with a crystal on the attiny85 is it …

2016年3月14日 · Hello all. I'm using an Arduino Uno R3 to try and generate a 1hz timer interrupt with a 20% duty cycle to mimic a GPS 1PPS output. I can produce the 1hz interrupt (and a 2hz …
