Sometimes slacking off is refreshing, but slacking off all the time is even better!

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

When we are surfing the internet and relaxing our brains (not just looking at legs, ahem), we need a colleague to help watch the boss. Even if the colleague is very reliable and reminds us on time, we still need to manually operate the keyboard to switch screens, which is not only unintelligent but also very dangerous.

So, I realized that 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)

• NOR Gate

The Leonardo uses an independent USB-Serial conversion chip and a single-chip Atmega32u4 to achieve USB communication and control. The native USB support of Atmega32u4 allows Leonardo to simulate a mouse and keyboard.

Circuit Connection

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

Wrap it with stickers (instantly upgrades its style).

Connect the receiver to the computer:

Key Functions

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

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

Keyboard.releaseAll() Release the keys to simulate pressing the combination keys:

Keyboard.releaseAll();

Usage Test

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

When the vibration sensor is hit, Leonardo simulates the Enter key.

Watch the effect:

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

Slacking off at work, and the boss shouts to fire you!!! But I’m not afraid of being fired; I can go work in a factory and screw bolts, I have connections.
