EMG detector is a bridge connects human body and electrical, the sensor gathers small muscle signal then process with 2th amplify and filter, the output signal can be recognized by Arduino. You can add this signal into your control system. Note: The sensor cannot be used for medical purposes. In standby mode, the output voltage is 1.5V. When detect muscle...
This small yet powerful 12V DC 2A Barrel Jack power module provides all your projects an easy to use power supply.
If you are in need of such a 4.0 BLE Bluetooth module, MCU can be set up,also can controlled by a remote Bluetooth device for setting,can transfer data, and can remotely control 10 PIO pins,so,the best choice is HM-10 bluetooth module. can replace HC-05, HC-06, HC-07 etc.
No goggles for use this toggle.
The very popular 595 shift register chip of the 74 series is used a lot by hobbyis because of its wide availability, good speed and simplicity. Just plug it on an arduino like shown in the tutorials and youi have 8 more outputs, put two and you have 16 more outputs ! (up to a lot of them actually, with only three pins !)
CD4021 is a cascadable 8bit parallel to serial shift register (basically the inverse of the 74hc595). Sometimes you'll end up needing more digital input than the pins on your microcontroller board can readily handle. Using a parallel to serial shift register allows you collect information from 8 or more switches while only using 3 of the pins on your...
Very useful and high quality 0.7mm 100g solder spool for all your needs. Ideal for all kind of work, even high precision ones as the wire is very thin.
A prototype AA battery case, it has on/off switch on the case, and it can be fully closed by cap and further screw it to close, so it’s very well protected.
