Download the Raspberry Pi Imager:
Insert a SD-Card.
Start the "Raspberry Pi Imager" program.
Select:
Insert the SD-Card again, after creating of the Image on the SD-Card has finished.
The SD-Card should be visible in the File-Explorer as boot
.
To make the Zero able to connect to the WiFi, it must get some settings to get this done.
The easiest way is to create a text file locally named as wpa_supplicant.conf
with the following content:
country=DE ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev update_config=1 network={ ssid="<my SSID>" psk="<my PASSWORD>" key_mgmt=WPA-PSK }
Replace the "<my*>" values with the access information of the Access Point.
Copy an empty file named SSH
, and wpa_supplicant.conf
to boot
. (Under Windows mostly drive D:
)
to the boot partition of the SD-Card:
ssh pi@raspberrypi
The standard password is raspberry
sudo apt update sudo apt upgrade
ssh pi@raspberrypi sudo apt install python3-picamera
ssh pi@raspberrypi nano startcam.sh
Create the script "/home/pi/startcam.sh" with the following content:
#!/bin/sh cd /home/pi python3 cam.py
Make the script executable:
chmod +x startcam.sh
Add the line "@reboot /home/pi/startcam.sh" to the crontab:
ssh pi@raspberrypi crontab -e no crontab for pi - using an empty one Select an editor. To change later, run 'select-editor'. 1. /bin/nano <---- easiest 2. /usr/bin/vim.tiny 3. /bin/ed Choose 1-3 [1]:
Close the nano editor with ctrl+x After edit to save the changes.
Check if the changes are saved:
crontab -l # Edit this file to introduce tasks to be run by cron. # # Each task to run has to be defined through a single line # indicating with different fields when the task will be run # and what command to run for the task # # To define the time you can provide concrete values for # minute (m), hour (h), day of month (dom), month (mon), # and day of week (dow) or use '*' in these fields (for 'any'). # # Notice that tasks will be started based on the cron's system # daemon's notion of time and timezones. # # Output of the crontab jobs (including errors) is sent through # email to the user the crontab file belongs to (unless redirected). # # For example, you can run a backup of all your user accounts # at 5 a.m every week with: # 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/ # # For more information see the manual pages of crontab(5) and cron(8) # # m h dom mon dow command @reboot /home/pi/startcam.sh
Reboot the Raspberry Pi:
sudo reboot

Under specific network conditions, the following system option (sudo raspi-conf) must be activated, if the WIOpi or CAM does not start at boot:
