Write a program for an Arduino Uno R3
Budget: $30 – $250 USD
Small project to program an Arduino Uno R3 to have to inputs.
1. A dry contact that is NC
2. A Ultrasonic Module HC-SR04 Distance Sensor or your suggestion for another component to do same job for proximity sensing.
Upon both 1,2 being met then send voltage or signal to close relay.
When either 1 or 2 are no longer true then drop voltage or signal to relay OR optionally wait “X” seconds then drop voltage or signal to relay.
Relay has control of 5v dc.
To let me know that you have read this far down into tue instructions please add the words “done it” at the end of your first sentence in the reply to me.
Will need Fritzing design and documentation for wiring etc.
Eventually will be replacing the Arduino for a atmega328 chip.
So will need to rehire for this later project.
