It may help to reboot the Mac after installation. The installation of the driver was straight-forward and I did not experience any issues with it afterwards. CH34X driver for macOS (M1/Apple Silicon).Hence, I had to download the latest CH340 driver from a Chinese manufacturer. It requires additional drivers and those you mostly find for macOS don’t do it on the Apple Silicon or M1 chips. I had written some smaller Sketches with my other Arduinos, but the Nano is quite different. Installing the drivers on the MacBook M1 Pro You’d probably use a proxy API in a real-world example or an MQTT gateway. Given the limited storage space, the amount of root certificates it can carry are limited.
Especially since the Nina chip does not contain all root SSL certificates, the desired certificates need to be installed on the chip. There are some obstacles and preparations required. Check the specs of your IR receiver about what voltages it supports. The IR receiver is connected to the 3V3+ as it is sufficient for it. Depending on what power source you’re using, you might consider either putting the LCD on the VIN or on the 5V+. The Nano’s 5V power output doesn’t really produce enough when connected to USB, so instead of the 5V output, I connected the power to the VIN where the juice of the USB input is on. The Nina Chip is onboard the Arduino, so there’s no wiring required for the networking. With the IR remote SS-PIN connected to PIN 10 on the Arduino Nano. I found both of the diagrams relatively easy to understand and just merged them together. LCD wiring diagram for the LCM1602C LCD.
I focused on the more complicated circuit diagram for the LCD and just changed the PIN for the IR receiver. My board is essentially a combination of two different circuit diagrams. Wiring up the Arduino Nano and the breadboard Soldering the components into a pocket-sized case could make a nice portable RSS feed reader. However using the Nina chip onboard the Arduino Nano RP2040 Connect in combination with a battery, makes a final construction very portable and low-energy. Yes, there are examples of feed readers out there using the USB bridge to connect to the Internet. Advantage of the Arduino Nano RP2040 Connect But, I had the IR receiver and the LCD lying around, so I wanted to give them a try. It also doesn’t have to be a remote control, hardware buttons could also do the job. While my construction and my code are more of a proof-of-concept, there are some very interesting use-cases for the Nano in combination with Wi-Fi and connected displays like LCDs or E-Ink.
