Feb 20, 2013 · Hi everyone I'm somewhat new to coding software but am experienced in logic-style electronics. sleep (sleep_time) # Set a long timeout to complete handshake timeout = arduino. Arduino Scheduler allows you run many tasks, with delay without locking the processor. delay: The duration the timer should wait for . I would like to make a system which will output two pairs of independent pulse trains: Pulse train 1 has 2 channels, each channel must put out 1 pulse with a width of 200uS, with a variable time until the next pulse on that channel (as specified by an analogue input). The code Dec 22, 2015 · I am writing an Arduino sketch to read temp data from multiple DS18B20 sensors and then write it to serial. The problem is that because the beep1 function is not asynchronous and uses delay(), it needs to run the melody first then the rest of the script continues.
