In this episode we take the TB6612FNG Dual H-Bridge motor driver and connect it to an Arduino & Raspberry Pi. We run two small gear motors that are great for small robotics.
DIY ATX Bench Power Supply
We build a bench top power supply from an ATX computer power supply. These bench top power supplies can provide quite a bit of current at 3.3, 5, and 12 volts. We 3d printed a panel that houses a switch to turn the unit on, a switch to silence the fan, an indicator LED and three sets of terminals for the three voltages mentioned above.
How to connect the MCP21017 GPIO Expander to an Arduino and Raspberry Pi
In this episode, we take a look at the MCP23017 GPIO Expander IC. With this IC, we can add 16 GPIO pins to the existing GPIO pins on an Arduino, Raspberry Pi, or any micro controller that has an i2c bus. They can be “stacked” for up to 128 additional GPIO pins! Bring on the LED’s!
How to connect the MCP3008 Analog to Digital Converter (ADC) to a Raspberry Pi and Arduino
In this episode we take a look at the MCP3008 Analog to Digital Converter IC. With this chip we can add Analog inputs to a Raspberry Pi, or extend the analog ports on an Arduino.
DHT11 and DHT22 Temp & Humidity Sensors on Raspberry PI and Arduino
Learn how to connect the DHT11 and DHT22 Temperature & Humidity Sensors to a Raspberry PI and Arduino. We cover all the connections for both sensors on both hardware platforms as well as provide and review the code to get them working!
How to Modify Servo for Continuous Rotation
Learn how to modify a standard servo for continuous rotation! In this video we cover removing the physical stop and replacing the potentiometer with static resistance. We also have a look at the code needed on Arduino & Raspberry PI, as well as how to calibrate your code for your newly modified Servo!
