TTL / PWM – how does it work with the laser.How to find a PWM pin on your board with a multimeter.Quite often we get questions about TTL and PWM. How does TTL works, how should it be connected, what voltage is needed to control TTL, what to do if you want to control the ...
How to Use a Multimeter Analog vs. Digital Alternating Current (AC) vs. Direct Current (DC) Video Basics of O-Scopes The main purpose of an oscilloscope is tograph an electrical signal as it varies over time. Most scopes produce a two-dimensional graph withtime on the x-axisandvoltage on...

Take a multimeter, put in continuity mode and check between motor signal and ground pins How to Check Motor Output You first want to check and confirm if the motor output is definitely faulty before attempting to fix it. The method I use to troubleshoot motor output is by measuring the vol...
HOW TO MAKE a PORTABLE WIND TURBINE: Generally when I want to get away from the city and camp, I take some kind of power source with me. Within my preferences are the Power Banks. With a small and light one, of approximately 40 Watt hours (Wh), I can cha
cable - a connector that my brushless motor needs. Note that your motor will likely require a different connector, or no connector at all. It is always a good idea to test an end-to-end integrity of the cable and its connectors. Lets buzz the wires using a multimeter. The cable is ...
Connect pin 3 from the Arduino board to the PPM pad on the Flight Controller. This is the Signal wire which will send all of the commands to the drone. And we're done with all the connections, now test that nothing is incorrectly soldered by using thecontinuity testeron your multimeter....
Take a battery, check its voltage using either a battery checker or multimeter. Then plug it in to the drone (remove propellers first!). If the reported voltage in the configurator (circle in red in the below image) is not the same as your measured voltage, then you should calibrate the...
IC1c decodes the 4013's Q outputs to provide a logic 0 output for one full mains cycle out of four. This is gated together with the mains zero-crossing signal in IC1d; using a couple of diodes and a resistor. IC1d acts as a NOR gate, allowing the transistors to switch on and ...
Oneshot and Multishot were introduced. These protocols are similar to PWM, but with much shorter signal width, they have much lower latency. Also they were designed to sync with the flight controller’s PID loop, enhancing performance by reducing jitter and delay in response to control inputs....
