Create an Embedded Fishing Tool for Work

Sometimes fishing is refreshing, and fishing all the time is even better!

Who can withstand the “996” or “715” work model? Even a donkey in a production team wouldn’t dare to do that. Donkeys need rest too; appropriate breaks can recharge our brains, allowing us to face more challenges and complete tasks more efficiently.

When we are surfing the internet and relaxing our brains (not looking at legs), we need our colleagues to keep an eye on the boss. Even if our colleagues are reliable and timely in reminding us, we still have to manually switch screens with the keyboard, which can be quite dangerous.

Thus, I realized I needed to do something…

Materials List

• DFRobot Leonardo & Xbee R3

• Gravity: Digital Wireless Switch (433MHz)

• Gravity: 3-80cm Infrared Digital Obstacle Avoidance Sensor

• Gravity: Digital Vibration Sensor (Arduino Compatible)

• NOT Gate

The Leonardo uses a dedicated USB-Serial converter chip and a single Atmega32u4 chip for USB communication and control. The native USB support of Atmega32u4 allows Leonardo to simulate a mouse and keyboard.

Circuit Connection

Put the sensor transmitter inside a box (you can cut the wires and re-solder them to reduce the size significantly).

Wrap it with stickers (instant upgrade).

Connect the receiver to the computer:

Key Functions

Keyboard.press() Select the keys you want to use:

Keyboard.press(KEY_LEFT_ALT);
Keyboard.press(KEY_TAB);

Keyboard.releaseAll() Release keys and simulate pressing a combination of keys:

Keyboard.releaseAll();

Usage Testing

When the transmitter detects someone passing by, the receiver automatically switches the screen.

When tapping the vibration sensor, Leonardo simulates pressing the Enter key.

Wake up, friend, you can’t really believe this, right?

Fishing at work, the boss shouts to fire you!!! But I’m not afraid of being fired; I can go work at a factory, I have connections.
