From the Makers of Everything Great comes your ESTES or Water Rocket Parachute Deployment Circuit.This sale is for the complete KIT: Deployment Circuit,Lipo Battery, Servo & Instructions.
If you wish to just purchase the main Board see my other listings.What the unit does: Attach the 7.3 Volt Battery and the LED will blink showing the seconds delay.Here how it works:1. Upon power-up MCU will recall last delay setting used and will flash. Delay is equal number of flashes in seconds (six flashes = six second delay).2. After that MCU is in idle mode. LED is OFF.
3. Press button once - and MCU will go to ARMED mode. It will move servo to 0degree and will wait for G-sensor. In this mode LED is strobe-like state (100msec ON - 900msec OFF)4. Upon G-sensor activation MCU will start counting delay (LED will be flashing 4 times per second)5. After timer expires - MCU will move servo to 180 degree and go to idle mode again.6. If you press and hold the button for more than 3 second - MCU will go to EDIT mode. LED will be turned ON till you hold the button. You need to release the button - so MCU will be waiting for new settings. Then press and hold one more time- you have to hold button for desired delay time. MCU will be blinking twice per second (to assist you in counting seconds) indicating that delay is being counted. Once you release button - new delay timing will take effect and will be stored in the memory (first delay will be checked to be between 1 second and 10 second. If not - it will be limited to either 1 or 10 second - whatever is closer). MCU will flash several time showing new delay (one flash = 1 second delay). New delay will be stored in memory.After that MCU will go to idle mode again waiting to be ARMED again.
