I have configured it to run in normal mode and the Prescaler is set to clk/8 (the clock frequency of Arduino is 16 MHz). 3V and loaded the example Arduino code. While it is can be useful when building own RC equipment, it does not help much when one has to deal with PPM (CPPM) signal. 76 seconds"-device that would replace the arduino?. A jumper pin matrix labeled “PWM swizzler” on the baseboard allows these four pins to be connected to any subset of the six shield-header pins normally used for PWM. So I use Arduino Uno board, DHT 11 sensor, I2C LCM1602 or LCD1602 display, a few wires and batteries to get the temperature and humidity. This is my second pulse motor and it incorporates a few concepts I wanted to explore.
