Creating an Embedded Fishing Tool for Work

Source | DF Maker Community

Sometimes slacking off is refreshing, but constantly slacking off is even better!

Who can withstand the “996” or “715” work model? Even the donkeys in the production team wouldn’t dare to do that; donkeys also need rest. Proper rest can recharge the brain, allowing us to face more challenges and complete work more efficiently.

When we surf the internet or take a break (uh, I mean relax the brain), we need a colleague to keep an eye on the boss. Even if the colleague is very reliable and reminds us in time, we still have to manually switch screens on the keyboard, which is not very smart and can be quite dangerous.

So, I realized that I should 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 an independent USB-Serial conversion chip, utilizing the single-chip Atmega32u4 for USB communication and control. The native USB support of Atmega32u4 allows the 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 (instantly upgrades the appearance).

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 to simulate pressing a combination of keys:

Keyboard.releaseAll();

Usage Testing

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

When the vibration sensor is tapped, the Leonardo simulates pressing the Enter key.

Watch the effect:

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

Slacking off at work, the boss is calling for dismissal!!! But I’m not afraid of being fired; I can go work in a factory and screw bolts, I have connections.
